Expander Control

The Expander Control provides an expandable container to host any content. You can show or hide this content by toggling a Header.

You can use these properties :

  • Header
  • HeaderTemplate
  • IsExpanded (define if the content is visible or not)

You can also use these events :

  • Expanded (fires when the expander is opened)
  • Collapsed (fires when the expander is closed)


<controls:Expander Header="Header of the expander"
    <Grid Height="250" Background="#FFF5F1D9">
        <TextBlock HorizontalAlignment="Center"
                   Text="This is the content"
                   VerticalAlignment="Center" />
