Hi,

I try to use the drag and drop of the TreeViewAdv.
I have different types of elements in the treeview and not all could be drop the each other.

Therefore I try to set the Data object of the DragTreeViewItemAdvEventArgs in the DragStart event.
In the DragOver event I want to read this information and set the correct Drag.Effect.
But the e.Data is null.

Is there a small example that shows the correct handling of the DragTreeViewItemAdvEventArgs
in the DragStart, DragOver and DragEnd events?

regards
Thomas

I too would like to know how to do this, because I need to drag a treeViewItemAdv onto a tabItemExt.

As far as within the treeview itself though, binding to the Entity Framework using a HierarchicalDataTemplate seems to have taken care of this automagically?  I noticed that if i drag a child onto its parent item, it will duplicate the child : |
