DoubleTap Event from Silverlight in WPF

I am building a .NET 4.0 WPF Application with items that the user can both drag and drop and execute.

  1. For the drag and drop, I am using the Tap and Slide (aka Tap and a Half): Microsoft Surface Touch: Tap, swipe, and beyond

  2. For the execute, I am using a Double Tap

Ran into conflicts between the two, since the tap and slide involved two TouchDown Events. I have a workaround, but it feels hacky (changed it to look for TouchUp Event) for the Double Tap.

What I really need is a DoubleTap Event.

I found Silverlight UIElement.DoubleTap Event.

However, it seems that this Event is not there for WPF, unless I am just plain missing something.

Is there any sort of alternative for WPF? Does anyone know why they would provide this event in Silverlight's UIElement, but not in WPF's UIElement?

Thank you,

Philip

  • As far as I know wpf doesn't have an explicit double tap event. But you can use single tap event (detect it as SystemGesture.Tap) and check if it's happened twice in a row.
