WPF ListBoxItem double-click?

Question

The WPF ListBox doesn't have a DoubleClick event, at least not as far as I can tell. Is there a workaround for this issue that would let me double-click on an item to have an event handler do something with it? Thanks for your help.

It is possible to bind commands with parameters to ListBoxItems without using code-behind or attached behaviors, simply by using InputBindings with a MouseBinding, as shown before in this answer.

Example ListBox with MouseBinding for LeftDoubleClick:

<ListBox ItemsSource="{Binding MyDataSource}">     <ListBox.ItemTemplate>         <DataTemplate>             <TextBlock Text="{Binding MySourceItemName}">                 <TextBlock.InputBindings>                     <MouseBinding MouseAction="LeftDoubleClick"                                   Command="{Binding DataContext.MyCommand, RelativeSource={RelativeSource AncestorType={x:Type ListBox}}}"                                   CommandParameter="{Binding MySourceItemId}" />                 </TextBlock.InputBindings>             </TextBlock>         </DataTemplate>      </ListBox.ItemTemplate> </ListBox> 

If the command is defined in the same DataContext as the ItemsSource of the ListBox, it can be bound by using the RelativeSource binding as included in the example.
