How can we create linkbuttons whose text is data-driven, but whose visibility is controlled from the front-end?

I've made a component based on a mx:TitleWindow that contains linkbuttons that I'm using as a context-menu.

The TitleWindow component c开发者_开发技巧ontains link buttons like this:

[Bindable]
private var _showEmailThis:Boolean = false;

[Bindable]
private var _showApproveThis:Boolean = false;

[Bindable]
private var _showReviewThis:Boolean = false;

<mx:LinkButton id="lnkEmailThis" 
               visible="{_showEmailThis}" 
               includeInLayout="{_showEmailThis}" 
               click="lnkEmailThis_click()" 
               label="Email this!" />

<mx:LinkButton id="lnkApproveThis" 
               visible="{_showApproveThis}" 
               includeInLayout="{_showApproveThis}" 
               click="lnkApproveThis_click()" 
               label="Approve this!" />

<mx:LinkButton id="lnkReviewThis" 
               visible="{_showReviewThis}" 
               includeInLayout="{_showReviewThis}" 
               click="lnkReviewThis_click()" 
               label="Review this!" />

This component contains a large number of links and is re-used by multiple modules in the same application.

Within each module, this component is used when a user clicks on a row in a datagrid.

The code looks like this:

In "Requests" module:

private function dgRequests_click(event:MouseEvent):void
{
    menu.showApproveThis = true;
    menu.showReviewThis = true;
}

In "Performance" module:

private function dgPerformance_click(event:MouseEvent):void
{
    menu.showEmailThis = true;
    menu.showReviewThis = true;
}

As you can see, the visibility of individual linkbuttons is controlled within each module by setting boolean properties.

If I alter this component to use a renderer, how can I control the visibility of the linkbuttons from the code in each module (there are over a hundred links with different functionality - not every link will be used in each module)? Note: it is not known from the back-end which grid within which module uses which link. This is set in the front end within each module's actionscript file.

e.g., if the XML looks like this:

<links>
   <link>
      <label>Email This</label>
      <visible>_showEmailThis</visible>
   </link>
   <link>
      <label>Approve This</label>
      <visible>_showApproveThis</visible>
   </link>
   <link>
      <label>Review This</label>
      <visible>_showReviewThis</visible>
   </link>
</links>

and I set the Email link to show in the module like this:

private function dgPerformance_click(event:MouseEvent):void
{
    menu.showEmailThis = true;
}

How do I make it take effect? Is there a way to control the visibility of a linkbutton within an item renderer in a component from the module that uses that component?

I'm not really sure I understand your question right. But if you have a component (or a group of 'em) sequentially repeating several times with different properties' values you should use mx:Repeater.

Adobe's docs on Repeater

There is also a live example in TourDeFlex (which I strongly recommend to install and use).

Looks like this is not possible.
