Drop item only outside of TreeView

[Ivan]

Hello,

i would like to only enable drag/drop effects outside of the TreeView. That means, when i drag the TreeViewItem inside TreeView, the DragDropEffects should be None, when the mouse is out of the TreeView, drop effects will be allowed.
1). I have tried the RadTreeView_ItemPrepared and set the PreparedItem.AllowDrop = false. But i can also drag a TreeViewItem and drop it after last TreeViewItem.
2). I tried to set DropPosition property of TreeViewDragDropOptions. But it could only be set to Inside :(

Any idea? Thanks.

Ivan

Hi Ivan,

To achieve this custom requirement you can use the events of the DragDropManager. You can explore our DragDrop section in the RadTreeView's online help. Its last article demonstrates how to deny a drop at certain places in the Tree. We believe it can help you proceed further.
