ListBox does not fire MouseRightButtonUp event

Question

Is there any particular reason why ListBox does not fire the MouseRightButtonUp event?

<ListBox x:Name="Users"
             ItemsSource="{Binding Users}"
             MouseRightButtonUp="MouseRightButtonUp" />

@kayboardP not really. I can use the MouseRightButtonDown event, which is fired, but not MouseRightButtonUp. — Fitzchak Yitzchaki, Jun 13 '11 at 13:56
Hi.I guess the problem is like Murven said, that the RightButtonUp event is handled by another control and is not getting to the ListBox. But if you add a MouseRightButtonDownHandler and just set e.handled = true in this handler, the MouseRightButtonUpHandler is called... Xaml: CodeBehind: private void downHandler(object sender, MouseButtonEventArgs e) { e.Handled = true; } — TerenceJackson, Jun 13 '11 at 18:02
@TerenceJackson interesting. I'll test this and let you know. — Fitzchak Yitzchaki, Jun 13 '11 at 18:17
@TerenceJackson yes, it's works. That's interesting. You should have added this as an answer. — Fitzchak Yitzchaki, Jun 14 '11 at 07:05

When a routed event is not fired in your control it means a control which is deeper in the visual tree is "eating" the event by marking it as handled in the event chain. In your case I suspect it is the ScrollViewer inside the ListBox eating the event.

Probably. Is there any suggestion for a solution? – Fitzchak Yitzchaki Jun 13 '11 at 18:16

here the answer taken from my previous comment ;)

I guess the problem is like Murven said, that the RightButtonUp event is handled by another control and is not getting to the ListBox. But if you add a MouseRightButtonDownHandler and just set e.handled = true in this handler, the MouseRightButtonUpHandler is called...

XAML:

<ListBox x:Name="Users" MouseRightButtonDown="downHandler" MouseRightButtonUp="upHandler"...>

Code Behind:

private void downHandler(object sender, MouseButtonEventArgs e) { e.Handled = true; }
