==Introduction to Task/Milestone Curtains in OnePager==

Illustrations used in this article are from OnePager Pro using data from Microsoft Project but the features, function, controls, and manual edits apply equally to other OnePager editions that '''import''' from data sources like Microsoft Excel, Smartsheet, Oracle Primavera P6, Microsoft Planner, Planisware Enterprise, Asana, and Wrike.

This article describes OnePager’s '''Task/Milestone Curtains''' feature.

==Overview==

'''Task/Milestone Curtains''' displayed in the '''Chart''' highlight '''timespans''' bounded by the '''Start '''and '''Finish '''dates of '''selected '''task bar/milestone symbols in a project that are relevant to a schedule conversation such as periods with critical schedule constraints, vacation periods, or project reviews. Strategically using '''Task/Milestone Curtains''' in the '''Chart '''is a way to focus on those '''timespans''' with your audience.

===Inserting Task/Milestone Curtains into the Chart===

'''Task/Milestone Curtains''' are inserted in an existing '''Chart''' by right-clicking on a '''selected''' task bar/milestone symbol and then clicking the '''Task/Milestone Curtain '''command in the right-click '''context menu''' shown below:

<center>[[File:P80-0_5_15-80-(1-1)-10242025.png]]</center>
<!--<center>P80-0_5_15-80-(1-1)-10242025.png</center>-->

Clicking the '''Task/Milestone Curtain''' command has the result shown in the illustration below:

<center>[[File:P80-0_5_15-80-(2)-09302025.png]]</center>
<!--<center>P80-0_5_15-80-(2)-09302025.png</center>-->

A '''curtain''' is placed from the '''time axis''' to the bottom of the '''Chart''' with the same '''color''' as the '''Foreground Color''' of the task bar/milestone symbol shown with 80 percent ('''%''') '''transparency''' by '''default'''.

===Using the Task/Milestone Curtains in the Chart===

'''Task/Milestone Curtains''' correspond to '''timespans''' for task bars/milestone symbols in the '''Chart'''.  Other '''periods of interest''' can also be '''inserted '''into the '''Chart''' and '''edited''' from the OnePager Pro, OnePager Express, or OnePager Bundle.

===Interaction Between Curtains, Time Cursor Shading, and Task/Milestone Curtains===

The '''Inserted Curtains '''feature, '''Time Cursor Shading '''feature, and the '''Task/Milestone Curtains''' feature can introduce '''Color''' into the '''Chart '''that may overlap other '''curtain graphs''' that you've previously or plan to '''Insert'''.  Depending on the '''properties''' you've established for these '''curtains''', some of your '''inserted Curtain graphs''' may be '''hidden'''.  If this turns out to be the case, you can adjust the '''Transparency''' controls for '''Time Cursor Shading''' and/or '''Task/Milestone Curtain '''or the''' Transparency''' controls for the other '''curtains '''to achieve the desired visual result.  '''Curtain '''controls also support moving the '''Curtains''' to different '''Z-Ordering levels''' using their right-click '''context menu Order''' commands

==About Task/Milestone Curtains==

A '''Task/Milestone Curtain''' is a vertical colored strip in the '''Chart''' that highlights a '''selected''' task bar/milestone symbol by '''default''' from the task bar/milestone symbol’s '''Start Date''' through its '''Finish Date'''.  For milestone symbols, given that they span a single day, the '''timespan''' of a''' default Task/Milestone Curtain''' is fourteen (14) days, seven (7) days on either side of the milestone symbol as illustrated for both task bars and milestone symbols below:

<center>[[File:P80-7_18_6-80-(1)-10022025.png]]</center>
<!--<center>P80-7_18_6-80-(1)-10022025.png</center>-->

'''Task/Milestone Curtains''' can be '''added''' to the '''Chart''', '''edited''', '''ordered''', '''deleted '''and propagated to '''all snapshots '''as necessary. A '''Task/Milestone Curtain''' right-click '''context menu''' is provided for accessing '''editing''' controls for individual '''Task/Milestone Curtains''' and for managing the appearance of '''Task/Milestone Curtains''' in some or all '''snapshots'''.  The full '''Task/Milestone Curtain''' right-click '''context menu''' with all the commands is shown below for a '''multi-snapshot Chart''':

<center>[[File:P80-7_18_6-80-(2)-10022025.png]]</center>
<!--<center>P80-7_18_6-80-(2)-10022025.png</center>-->

==Adding a Task/Milestone Curtain to a Selected Task Bar or Milestone Symbol==

All OnePager editions supports the '''new Task/Milestone Curtain '''feature whereby you can create a '''curtain''' on a task bar/milestone symbol by using a single command from the right-click '''context menu'''.  The new command is shown in the illustration below:

<center>[[File:P80-0_5_15-80-(1-1)-10242025.png]]</center>
<!--<center>P80-0_5_15-80-(1-1)-10242025.png</center>-->

Clicking the '''Task/Milestone Curtain''' command creates a basic '''curtain''' extending from the selected task bar’s '''Start Date''' to '''Finish Date''' with the same '''Color''' as the '''selected''' task bar/milestone symbol but with '''80% Transparency''' as shown below:

<center>[[File:P80-0_5_15-80-(2)-09302025.png]]</center>
<!--<center>P80-0_5_15-80-(2)-09302025.png</center>-->

Once created, the '''Task/Milestone Curtain''' is '''selectable''' with a left-click in the area of the '''curtain''' as shown here:

<center>[[File:P80-0_5_15-80-(3-1)-10032025.png]]</center>
<!--<center>P80-0_5_15-80-(3-1)-10032025.png</center>-->

When a milestone symbol is '''selected''' and a '''Task/Milestone Curtain''' is created for the '''selected''' milestone symbol, the '''Chart '''looks like this:

<center>[[File:P80-0_5_15-80-(3A)-09302025.png]]</center>
<!--<center>P80-0_5_15-80-(3A)-09302025.png</center>-->

Since milestone symbols, by definition, have a '''one day (1) duration''', to make the '''Task/Milestone Curtain''' visible, the '''default timespan''' for a '''selected''' milestone symbol’s '''Task/Milestone Curtain''' is '''fourteen (14) days''' which generally corresponds to the size of most OnePager milestone symbols.  For clarity, the '''Task/Milestone Curtain''' spans '''seven (7) days''' before and after the milestone symbol’s '''Start Date '''and '''Finish Date'''.

You have the capability to '''edit''' the '''default''' settings in the '''Task/Milestone Curtain Properties''' form where the '''default''' settings for a milestone symbol are shown below:

<center>[[File:P80-0_5_15-80-(3B)-09302025.png]]</center>
<!--<center>P80-0_5_15-80-(3B)-09302025.png</center>-->

As a further example, suppose the '''days before start date''' and '''days after finish date values''' for the milestone symbol in the illustration above are reduced to '''one (1) day''' each.  Doing so creates a '''Chart '''that looks like this:

<center>[[File:P80-0_5_15-80-(3C)-09302025.png]]</center>
<!--<center>P80-0_5_15-80-(3C)-09302025.png</center>-->

Reducing the '''days before start date''' and '''days after finish date values''' one more integer value essentially '''hides''' the '''Task/Milestone Curtain''' for the '''selected''' milestone symbol.

==Editing Task/Milestone Curtains in the Chart==

===The Task/Milestone Curtain’s Right-Click Context Menu===

Once a '''Task/Milestone Curtain''' is added to the '''Chart''', it may be '''selected''' with a right-click which assesses its right-click '''context menu''' as shown here:

<center>[[File:P80-0_5_15-80-(3-1)-10032025.png]]</center>
<!--<center>P80-0_5_15-80-(3-1)-10032025.png</center>-->

There are three commands in the '''Task/Milestone Curtain’s''' left-click '''context menu''' for a '''single snapshot Chart''' shown above:


:1) '''Delete:''' The '''Delete''' command works exactly like '''Delete '''commands for other objects in OnePager (e.g., '''Images''', '''Task Links''', '''Time-Axis Curtains''', '''Comment Boxes''', and '''Free Boxes''').  When the '''Chart''' consists of one '''snapshot''', the '''Delete''' command, when clicked, '''deletes''' the '''Task/Milestone Curtain''' from only the single '''snapshot'''.  In '''multi-snapshot Charts''', the '''Delete''' command gives you the option to '''Delete''' the '''Task/Milestone Curtain''' from the current '''snapshot''' or '''all snapshots'''.

:2) '''Order:'''  The '''Order''' command works exactly the same as other '''Order''' commands available in OnePager.

:3) '''Properties…:'''  Clicking the '''Properties…''' command access the '''Task/Milestone Curtain Properties''' form shown below:

<center>[[File:P80-0_5_15-80-(4)-09302025.png]]</center>
<!--<center>P80-0_5_15-80-(4)-09302025.png</center>-->

When a '''Chart''' consists of '''multiple snapshots''', the task bar/milestone symbol right-click '''context menu''' has an added command as shown below:

<center>[[File:P80-0_5_15-80-(5)-09302025.png]]</center>
<!--<center>P80-0_5_15-80-(5)-09302025.png</center>-->

Clicking the '''Put at all snapshots''' command tells OnePager to place a '''Task/Milestone Curtain''' for the''' selected''' task bar/milestone symbol, if it appears in any additional '''snapshots''', in the '''Chart'''.  If the task bar/milestone symbol does not appear in a '''snapshot''', neither does its associated '''Task/Milestone Curtain'''.

===Using the Task/Milestone Curtain Properties Form===

You have the capability to modify a '''Task/Milestone Curtain''' after it is created in the '''Chart''' in either of two ways:

:1) Accessing the '''Task/Milestone Curtain Properties''' form by right-clicking in the '''Task/Milestone Curtain area''' to access the right-click '''context menu''' and then clicking the '''Properties…''' button. 

:2) After the '''Task/Milestone Curtain''' for a '''selected''' task bar/milestone symbol is '''created''', you can right-click on the task bar or milestone symbol to access the task bar’s right-click '''context menu'''.  With the right-click '''context menu''' accessed, again click the '''Task/Milestone Curtain''' command and the '''Task/Milestone Curtain Properties''' form is accessed for''' editing'''.  Actually, the first method is the easiest.

After accessing the '''Task/Milestone Curtain Properties''' form, the form looks like this for a '''selected''' task bar:

<center>[[File:P80-0_5_15-80-(6)-09302025.png]]</center>
<!--<center>P80-0_5_15-80-(6)-09302025.png</center>-->

====Task/Milestone Curtain Color and Transparency====

As shown in the illustration above, there are two control groups provided in the form.  The top control group provides control over the '''Fill color''' and '''Transparency''' of the '''Task/Milestone Curtain''' created for the''' selected''' task bar/milestone symbol.  By '''default''', the '''Foreground Fill Color''' selected by OnePager for the '''Task/Milestone Curtain''' is the '''Foreground Color''' of the '''selected''' task bar/milestone symbol in this case and the '''default Transparency''' is set to '''80 percent''', a value you can also change.  After the '''initial Fill Color''' selection for the '''Task/Milestone Curtain''', based on the selected task bar/milestone symbol’s '''Foreground Fill Color''', future '''edits''' of the '''Fill Color''' for the '''Task/Milestone Curtain''' are '''independent '''of the '''Foreground Color edits''' for the '''selected''' task bar/milestone symbol and vice-versa.

Clicking the '''Fill color''' dropdown arrow accesses the Standard OnePager '''Color Chooser''' form used throughout OnePager.  You can use the up and down arrows in the '''Transparency''' control to change the '''Transparency percent''' value of the selected '''Task/Milestone Curtain'''.

====Shading Extent Controls-Begin and End Shading====

The second control group provides controls over the '''timespan extent''' of the '''Task/Milestone Curtain''' where you have two options for where to '''Begin '''the '''Task/Milestone Curtain''' with respect to the '''selected''' task bar/milestone symbol and where '''End''' the '''Task/Milestone Curtain''':

:1) '''Setting Days Before Start Date and Days After Finish Date:'''  The '''default '''setting for this control group is shown in the illustration above where the '''radio buttons''' are set for '''Begin Shading''' and '''End Shading''' at zero (0) '''days before start date''' and '''days after finish date '''for a task bar.  For a milestone symbol, the two '''default settings''' are seven (7) days. The result of these '''default''' settings as shown in the '''Chart '''illustrations above.

:2) '''Setting at Left Edge and at Right Edge of Chart:'''  As an alternative, you can extend the''' selected''' '''Task/Milestone Curtain''' from the '''selected''' task bar/milestone symbol’s '''Finish Date''' to the '''left edge''' of the '''Chat''' or from the '''selected '''task bar/milestone symbol’s '''Start Date '''to the '''right edge''' of the '''Chart''' as shown in the two illustrations below:

<center>'''Selected Task/Milestone Curtain Extended to Left Edge of the Chart'''</center>
<center>[[File:P80-0_5_15-80-(7)-09302025.png]]</center>
<!--<center>P80-0_5_15-80-(7)-09302025.png</center>-->

<center>'''Selected Task/Milestone Curtain Extended to Right Edge of the Chart'''</center>
<center>[[File:P80-0_5_15-80-(8)-09302025.png]]</center>
<!--<center>P80-0_5_15-80-(8)-09302025.png</center>-->

As shown above, the '''Task/Milestone Curtain''' always spans the '''Start/Finish Dates''' of the '''selected''' task bar/milestone symbol.

====Shading Extent Controls-Days Before Start and Days After Finish====

The controls for '''Days Before Start''' and '''Days After Finish''' with the settings '''defaulted''' to zero (0) are illustrated above.  You can set any '''number of days''' using the up and down arrows in the control to '''timespan extent''' of the '''Task/Milestone Curtain '''to the left ('''days before start date''') or to the right ('''days after finish date''') up to the '''Start''' and '''Finish Dates''' of the '''Chart'''.  The controls only process '''positive integers'''.  '''Negative numbers''' are changed to zero (0).  The '''Task/Milestone Curtain''' for a '''selected''' task bar/milestone symbol won’t extend beyond the '''Chart’s Start Date''' or its '''Finish Date''' no matter what the values placed in the '''days before start date''' or '''days after finish date''' controls.

Here’s an example for a '''Task/Milestone Curtain''' established on a '''selected''' task bar/milestone symbol extending '''fourteen (14) days before''' the task bar’s '''Start Date''' and extending '''fourteen (14) days''' after the task bar’s '''Finish Date''':

<center>[[File:P80-0_5_15-80-(9)-09302025.png]]</center>
<!--<center>P80-0_5_15-80-(9)-09302025.png</center>-->

==Deleting Task/Milestone Curtains==

'''Deleting Task/Milestone Curtains''' is similar to '''deleting''' other shapes in the '''Chart '''such as a '''Comment Boxes'''. First, right-click in the '''Task/Milestone Curtain area''' to access the '''Task/Milestone Curtain’s''' right-click '''context menu''' and click the '''Delete''' command in the '''context menu''' shown below:

<center>[[File:P80-7_18_6-80-(3)-10022025.png]]</center>
<!--<center>P80-7_18_6-80-(3)-10022025.png</center>-->

The illustration above shows the '''Delete '''command in the '''Task/Milestone Curtain’s''' right-click '''context menu''' where the '''Chart '''contains only one '''snapshot'''.  The '''Delete '''command for a '''Task/Milestone Curtain’s''' right-click '''context menu''' is altered when the '''Chart''' contains two or more '''snapshots''' as in the illustration shown here:

<center>[[File:P80-7_18_6-80-(4)-10022025.png]]</center>
<!--<center>P80-7_18_6-80-(4)-10022025.png</center>-->

The illustration above shows the '''Delete''' sub-commands which appears in the case where the '''Chart''' has '''two or more snapshots'''.  When the '''Delete''' command is clicked in a '''Chart''' with only '''one snapshot''' no '''Delete''' sub-commands are shown.

Using the sub-command '''Delete From this snapshot''' this command '''deletes''' the '''Task/Milestone Curtain''' from the '''current displayed snapshot'''.  '''Task/Milestone Curtains''' that remain in other '''snapshots''' are treated as a single entity with respect to their '''properties'''. The sub-command '''Delete From all snapshots''' '''deletes''' all '''Task/Milestone Curtains''' from '''all snapshots'''.

==Z-Ordering Task/Milestone Curtains==

'''Task/Milestone Curtains''' can be '''Z-Ordered''' in the '''Chart''' from '''front to back''' in the same way that '''Free boxes '''can be '''Z-Ordered''' using the same right-click''' context menu''' command and sub-commands. 

For more information on '''Z-Ordering Free boxes''' in the '''Chart''', please see this section at the article at:  

<center>
{| class="wikitable"
| [[Creating and Managing Free Boxes for Version 8.0#Ordering Free Boxes | Ordering Free Boxes]] <!--14.0.1-80-->
|}
</center>

When the '''Z-Order’s''' sub-commands are used, the results with respect to the '''Z-Order Level''' positioning of the '''Task/Milestone Curtain''' are shown in '''all snapshots''' where the '''Task/Milestone Curtain''' is showing.

==Putting Curtains in Some Snapshots==

When a task bar/milestone symbol’s right-click '''context menu''' is used to '''add''' a '''Task/Milestone Curtain''' to a '''multi-snapshot Chart''', the '''Task/Milestone Curtain''' is '''added''' in '''all snapshots'''.  

===Displaying Task/Milestone Curtains in Some Snapshots===

There is no '''Attach to all snapshots '''checkbox in the '''Task/Milestone Curtain Properties''' form as there is in the '''Create or edit comment box '''form because all '''added Task/Milestone Curtains''' are placed in '''all snapshots''' by '''default'''.  The recommend way to display a '''Task/Milestone Curtains''' in '''one '''or a''' select set of snapshots''' is to use this two-step procedure:

:1)  First create the '''Task/Milestone Curtain''' with its desired '''properties''' making the '''Task/Milestone Curtain''' appear in '''all snapshots''' as the '''default''' result.

:2)  Then,  going to each '''snapshot''' where you '''do not''' want the '''Task/Milestone Curtain''' to appear, use the '''Task/Milestone Curtain’s''' right-click '''context menu's Delete''' command to '''individually delete''' the '''undesired Task/Milestone Curtain''' from that '''snapshot''' where the '''Task/Milestone Curtain''' should '''not be''' showing.

Repeat this process for each '''snapshot''' where the '''Task/Milestone Curtain''' should '''not''' appear.

===Reinstating Task/Milestone Curtains in the Future===

Subsequent project demands can require that you later need to put the '''Task/Milestone Curtain''' back in '''all snapshot''' or into a specific '''snapshot'''.   To do this, just follow these steps. 

:1)  To put a '''Task/Milestone Curtain''' in '''all snapshots''', use the '''Put at all snapshots''' command found in the '''Task/Milestone Curtain’s''' right-click '''context menu''' for the existing '''Task/Milestone Curtain''' in the '''snapshot''' where it is showing as done below:

<center>[[File:P80-7_18_6-80-(5)-10022025.png]]</center>
<!--<center>P80-7_18_6-80-(5)-10022025.png</center>-->

:2)  After clicking the '''Put at all snapshots''' command, the '''selected''' '''Task/Milestone Curtain''' is shown in '''all snapshots'''. 

:3)  By using the first procedure above, you can now selectively '''delete Task/Milestone Curtains''' from '''snapshots''' where the selected '''Task/Milestone Curtains''' are '''not''' desired.

===Editing Task/Milestone Curtains in Snapshots===

Whenever you '''edit''' the '''properties''' of a '''Task/Milestone Curtain''' in any '''snapshot''', the '''edited Task/Milestone Curtain''' is '''updated''' with these '''edits''' in '''all snapshots''' where the '''Task/Milestone Curtain''' appears. This being the case, a '''Task/Milestone Curtain''' is never considered as a '''maverick''' because once its '''properties''' are '''set''' or '''edited''' it appears the same in '''all snapshots''' where it is showing.

==Task/Milestone Curtains On Virtual Summary Tasks (VST)==

===Making a Virtual Summary Task with Task/Milestone Curtains===

'''Task/Milestone Curtains''' can be created on '''Virtual Summary Tasks''' ('''VST''') using the steps associated with '''making''' and '''unmaking virtual summary tasks''' as shown in the illustrations that follow:

:1)  Select the task bars/milestone symbols to become part of a single '''VST''', right-click on the task bar/milestone symbol to access the '''right-click context menu''', and click the '''Make into virtual summary task command''':

<center>[[File:P80-7_18_6-80-(5A)-10132025.png]]</center>
<!--<center>P80-7_18_6-80-(5A)-10132025.png</center>-->

:2) After creating the '''virtual summary task, the '''Chart''' looks like this:

<center>[[File:P80-7_18_6-80-(5B)-10132025.png]]</center>
<!--<center>P80-7_18_6-80-(5B)-10132025.png</center>-->

:3) After creating the '''virtual summary task''', right-click on the '''VST''' to access the '''right-click context menu''' and click the '''Task/Milestone Curtain''' command to create a '''Task/Milestone Curtain''' on the '''selected VST''':

<center>[[File:P80-7_18_6-80-(5C)-10132025.png]]</center>
<!--<center>P80-7_18_6-80-(5C)-10132025.png</center>-->

:4) The resulting '''Task/Milestone Curtain''' created for the '''selected virtual summary task''' looks like this:

<center>[[File:P80-7_18_6-80-(5D)-10132025.png]]</center>
<!--<center>P80-7_18_6-80-(5D)-10132025.png</center>-->

===Unmaking a Virtual Summary Task with Task/Milestone Curtains===

'''Unmaking''' a '''virtual summary task''' with a created '''Task/Milestone Curtain''' '''unmakes''' the '''virtual summary task''' and restores the original task bar/milestone symbols to their original configuration.  However, the created '''Task/Milestone Curtain''' is retained with the '''start/finish dates''' associated with the created '''virtual summary task''' as illustrated below.

:1) To '''unmake the virtual summary task''' right-click to '''select the VST''' and access the right-click '''context menu''' and click the '''Unmake virtual summary task''' command as shown here:

<center>[[File:P80-7_18_6-80-(5E)-10132025.png]]</center>
<!--<center>P80-7_18_6-80-(5E)-10132025.png</center>-->

:2) Clicking the '''Unmake virtual summary task''', containing a '''Task/Milestone Curtain''', restores the members of the '''VST''' to their to their original configuration and retains the '''Task/Milestone Curtain''' with the '''start/finish dates''' of the previously selected '''VST''' as shown below:

<center>[[File:P80-7_18_6-80-(5F)-10132025.png]]</center>
<!--<center>P80-7_18_6-80-(5F)-10132025.png</center>-->

After '''unmaking the virtual summary task''' you have the option to retain the '''Task/Milestone Curtain''', change its '''properties''', or '''delete''' it from the '''Chart'''.

For more in depth information on '''Virtual Summary Tasks''', please see the article listed in the table below:

</center>

==Task/Milestone Curtains Created on Absorbed Tasks==

Creating and managing '''Task/Milestone Curtains''' on '''Absorbed task bars''' is essentially the same as described in the previous sub-section.

For more detailed information on '''Absorbed tasks''', please see the article listed in the table below:

</center>

==Multiple and Overlapping Task/Milestone Curtains in the Chart==

'''Task/Milestone Curtains''' are applied to a task bar/milestone symbol in the '''Chart''' from its '''Start Date''' to its ''' Finish Date'''.  When there are task bars/milestone symbols in the '''Chart''' with overlapping '''Start/Finish Dates''' there are situations where the application of '''Task/Milestone Curtains''' overlap in the '''Chart''' as shown in the illustration below:

<center>[[File:P80-7_18_6-80-(5G)-101142025.png]]</center>
<!--<center>P80-7_18_6-80-(5G)-101142025.png</center>-->

In the illustration above the '''Task/Milestone Curtains''' are different '''colors''' which make it a bit easier to use the mouse left-click to select the '''Task/Milestone Curtain''' or the mouse right-click to access the '''Task/Milestone Curtain''' right-click '''context menu'''.  Accessing the desired '''Task/Milestone Curtain''' right-click '''context menu''' allows you to '''Delete''' the selected '''Task/Milestone Curtain''', '''Order''' it in the '''Chart''', or access it's '''Task/Milestone Properties''' form to make '''edits'''.  

To highlight a '''Task/Milestone Curtain''' to distinguish it in this '''overlap''' environment, you have the option to change it's '''Order''' position, it's '''color''', or it's '''transparency''' value.  This may be more difficult when all '''Task/Milestone Curtains''' in the '''Chart''' are the same '''color''' and '''transparency''' as shown in the illustration here:

<center>[[File:P80-7_18_6-80-(5H)-101142025.png]]</center>
<!--<center>P80-7_18_6-80-(5H)-101142025.png</center>-->

OnePager keeps track of all '''Curtain''' types and the list can be found in the '''Chart Properties''' form's '''Time Axis''' tab's '''Format''' sub-tab's '''Curtains and Timespans Grid''' covered in the next sub-section.

==Task/Milestone Curtain Properties When Task Bar/Milestone Symbol Representations Change==

With all task bar/milestone symbols in the '''Chart''' you always have the option to change their '''representation'''.  For example, a task bar can be '''represented''' by a '''Milestone at start''' or a '''Milestone at finish'''.  If a task bar with a '''Task/Milestone Curtain''' associated with it has its '''representation changed''' to a '''Milestone at start''' the associated '''Task/Milestone Curtain's days before start date''' and '''days after finish date''' values are changed from zero ('''0''') to seven ('''7''').  This convention was discussed earlier and is done to make sure the '''Task/Milestone Curtain''' remains visible on the new milestone symbol.  

There may be a requirement to change the '''representation''' of this newly created milestone symbol now associated with a '''Task/Milestone Curtain''' back to a task bar '''representation'''.  When you make the '''representation''' change, OnePager retains the value of seven ('''7''') for the '''days before start date''' and the '''days after finish date'''.  This is done to give you the option to change these two values to specifically meet the needs of your schedule conversation by accessing the '''Task/Milestone Curtain's right-click '''context menu''', clicking the '''Properties...''' command, and making the change in the '''Task/Milestone Curtain Properties''' form.

As an example, the three illustrations below show (1) the addition of a '''Task/Milestone Curtain''' to a task bar, (2) the change in '''representation''' of the '''selected''' task bar to a milestone symbol with a '''Task/Milestone Curtain''', and (3) the change in '''representation''' of the milestone symbol back to a task bar with its associated '''Task/Milestone Curtain''':

==Keeping Track of Curtains in the Chart==

In any '''Chart '''where '''curtains''' of various types are used for multiple purposes, it may become necessary to consult a list of '''curtain entities''' that are in the '''Chart''' or '''snapshots'''. The '''Time Axis Levels and Cells''' feature of OnePager provides a location where all '''curtains '''in the '''Chart''' are listed. Whenever you '''add''' a '''curtain''' to the '''Chart''', regardless of the method used, an entry is made in the '''Curtains and Timespans Grid '''found in the '''Chart Properties''' '''form's Time Axis''' tab's '''Format''' sub-tab as shown below for the example used in this article thus far:

<!--<center>P80-7_18_6-80-(6)-10022025.png</center>-->

The '''Grid''' entry for the '''Task/Milestone Curtain''' provides access to the Standard OnePager '''Color Chooser''' form for the '''Task/Milestone Curtain''' which can be '''edited''' in the '''Grid'''. Because task bars/milestone symbols have their '''Start/Finish Dates''' fixed in OnePager these '''dates''' cannot be '''edited'''.

Using the illustration from the pervious section where there were three (3) '''Task/Milestone Curtains''' with the same '''color''' and same '''transparency''', the '''Curtains and Timespans Grid''' looks like this:

<!--<center>P80-7_18_6-80-(6A-1)-10142025.png</center>-->

==Summary==

The new '''Task/Milestone Curtain''' feature is provided to give you additional capabilities to highlight task bar/milestone symbol related issues in schedule conversations.  Controls are provided for you to '''edit''' the '''Color''' and '''Transparency''' of the '''Task/Milestone Curtain''' associated with the '''selected '''task bar/milestone symbol.  Additionally, controls are provided for extending the '''timespan''' of the '''Task/Milestone Curtain''' around the '''selected''' task bar/milestone symbol to suit the goals and objectives of the schedule conversation.  Further, '''Task/Milestone Curtains''' can be shown in some or '''all snapshots''' as required.  Finally, when desired, '''Task/Milestone Curtains''' can be '''deleted''' from some or '''all snapshots'''.
