Silverlight Handle App MouseLeftButtonDown?

Question

In my silverlight project I have a Menu, that I want to close it if I click anywhere outside it. I add handler to the click event on App:

AddHandler App.Current.RootVisual.MouseLeftButtonDown, AddressOf HideMenu

But the problem that: it does not enter the Handler when I click on any other command, or click on the same control that have the context menu, it is enter only when I click on an empty area outside the menu.

Thanks.

I wasn't aware that was a signature of AddHandler that only takes 2 parameters, perhaps its a VB thing that you are getting away with it and its defaulting the third parameter to False. This parameter is the handledEventsToo parameter which indicates you want your handler to execute even when some other control has handled the event.

I guess the VB would look like this:-

AddHandler App.Current.RootVisual.MouseLeftButtonDown, AddressOf HideMenu, True

Edit

Lets ditch this VB code which is wrong anyway. Here is what the code should look like in C# (you must be fairly familar with translating since the vast majority of code examples on the Web for silverlight will be in C#).

 this.AddHandler(UIElement.MouseLeftButtonDownEvent, HideMenu, true);

Where this code is in the code behind of the containing UserControl and HideMenu has this signature:-

 void HideMenu(object sender, MouseEventArgs e)
 {
 }
