How can I trigger a control event when a ListViewItem is selected?

Question

I have an image that I want to show only when a ListViewItem is selected. The code I have isn't working, but I think it illustrates what I want to accomplish.

<GridViewColumn>
   <GridViewColumn.CellTemplate>
      <DataTemplate>
         <Image Height="20">
            <Image.Style>
               <Style TargetType="{x:Type Image}">
                  <Setter Property="Visibility" Value="Collapsed" />
                  <Style.Triggers>
                     <DataTrigger Binding="{Binding RelativeSource=
                           {
                              RelativeSource 
                              Mode=FindAncestor, 
                              AncestorType={x:Type ListViewItem}
                           }, Path=IsSelected}" Value="True">
                        <Setter Property="Visibility" Value="Visible" />
                        <Setter Property="Source" Value="/Russound.Windows;component/Resources/2leftarrow-64.png" />
                        <Setter Property="ToolTip" Value="Selected" />
                     </DataTrigger>
                  </Style.Triggers>
               </Style>
            </Image.Style>
         </Image>
      </DataTemplate>
   </GridViewColumn.CellTemplate>
</GridViewColumn>

Answer 1

Simply change the default Visibility to Hidden instead of Collapsed.

Apparently, if you use Collapsed, the element is removed from the visual tree and the RelativeSource no longer works.

Answer 2

When dealing with binding issues, I generally search through the Output window to find any binding errors. They all start with System.Windows.DataError. So, are there any errors in the Output window?
