OnDragQuery Not triggered by Touch

[Pat Tormey]

Ok So here's the deal.
 VS2010 WPF Telerik 2011 Q1

The sample code runs just fine for Drag & Drop with either mouse of touch.. ViewSonic MultiTouch Monitor and HP Slate 500.

BUT my own code works with with the mouse and not Touch.. the OnDragQuery event never fires for Touch..

Any ideas??

Thanks

I've been fighting this for the last few days. This appears to be a bug. For me the solution was to apply a theme. I

added telerik:StyleManager.Theme="Office_Black" to the ListBox. Then touch started to work. Good luck...

WOW.. Apply a theme to get Drag and Drop Touch working?

It Worked! I own you a beer.. or several..
Alright that might be hard to do.. So I'll send $50 to Japan Relief

How did you ever figure that out?? I would never have guessed.....

THANKS!
