Question

I am having some difficulties binding a command (ICommand) to the MouseBinding of a ListView.
I used this piece of XAML code to test the different mouse gestures:

<ListView.InputBindings>
    <MouseBinding Command="{Binding OpenSOACommand}" Gesture="LeftClick" />
    <MouseBinding Command="{Binding OpenSOACommand}" Gesture="MiddleClick" />
    <MouseBinding Command="{Binding OpenSOACommand}" Gesture="LeftDoubleClick" />
</ListView.InputBindings>

The LeftClick and LeftDoubleClick gestures aren’t triggered, yet the MiddleClick mouse binding works perfect (I have tested the mouse bindings one at a time as well…).

Is there a difference in the way the LeftDoubleClick and MiddleClick Gesture is handled? And if there is, how can I bind my ICommand to the LeftDoubleClick gesture?

Thanks!

Answer 1

The default Click event for the ListView is marking the event as handled. Try using PreviewLeftClick and PreviewLeftDoubleClick instead

EDIT

Since MouseBindings does not contain a PreviewLeftClick or PreviewLeftDoubleClick, try using the AttachedCommandBehavior code found here which allows you to attach a Command to just about any Event

For example,

<ListView local:CommandBehavior.Event="PreviewMouseDown" 
          local:CommandBehavior.Command="{Binding OpenSOACommand}" />
