  • Article

3/26/2014

You can use the RemoveElementAction behavior to easily remove an element from a logical tree in a XAML for Windows Embedded application. For example, the following XAML example shows you how to create a button that will be removed from the application entirely the first time the button is clicked.

<!-- This collection element might exist if you have already added other behaviors. -->
<i:Interaction.Triggers>

   <!-- Specify the name of the object (button) whose event will cause the property change.
      Also specify the event name (Click). -->
   <i:EventTrigger EventName="Click" SourceName="button">

      <!-- Specify the name of the object (button) which will be removed.-->
      <ei:RemoveElementAction TargetName="button"/>

   </i:EventTrigger>
</i:Interaction.Triggers>

Important

Subsequent invocations of the action will have no effect, because the element has already been removed from the tree.
