How to Cancel DragInitialize Event in RadTree using MVVM

[Tayyaba]

Hi, 

I want to cancel the drag start of a node in treeView. I have seen this link for cancelling drag start. But I couldn't find a way to do it in MVVM. In ViewModel we dont have those DragInitializeEventArgs which I can set data to null to cancel the event.

Please let me know how can I achieve this.

Regards,
