We are using the Radtreeview to show some virtual folders. We have a require ment to drop files inside the treeview.

ie, the end user can drag and drop the items from the windows explorer to the RadTreeView. But the treeview items does not automatically expands when the user drags the file over the treeview item. 

We just like to do the same of windows explorer treeview drag drop functionality. The windows explorer (win forms) treeview automatically expands while drag over an item .

How to achive that in RadTreeview?

Which build you mentioned?

We are using Rad Controls for WPF 2009.1 (2009.1.0424.35).
We checked the RadControls_for_WPF_2009_1_612_trial.zip (2009.1.0612.35). We got the same problem.

hai,

I think the fix doesn't work for the external items like files dragged from explorer on to the treeview item.
It seems to work fine for dragging same treeview items.

oh.

So the rad treeview supports the drag and drop only between the items itself. 

We cant do any drag and drop form other controls/other applications. is that right? it so sad.

Thank you for your reply....

Hi prakash,

The TreeView supports dragging to and from other controls in the same application window out of the box.

If you want to drag files from different applications or windows, you need to use the built-in WPF DragDrop. Then you will need to handle all the events associated with it.
