Question

I have a collection of objects which I bind to a ListBox, but I actually only want to display the selected element, and not the entire collection. What’s the best way to go about this? Use a different control?

I think I can do a Visibility ValueConverter which checks the IsSelected attribute — and if not selected collapses… but I’m still interested in other ideas.

Since the entire purpose of a ListBox is to display multiple items and provide the user with a way to select them, yes, I’d use a different control.

Or you could do this, which is getting into the territory of stupid:

<ListBox.ItemContainerStyle>
   <Style TargetType="ListBoxItem">
      <Style.Triggers>
         <Trigger Property="IsSelected" Value="false">
            <Setter Property="Visibility" Value="Collapsed"/>
         </Trigger>
      </Style.Triggers>
   </Style>
</ListBox.ItemContainerStyle>
