Disable Drop at Specific Location

In order to disable the drop operation on a specific treeview item, you need to set the boolean RadTreeViewItem property IsDropAllowed to False.

<telerik:RadTreeViewItem Header="Tennis" IsDropAllowed="False"> 

private void DisableDropOnSpecificItem() 
{ 
    radTreeViewItemTennis.IsDropAllowed = false; 
} 
Private Sub DisableDropOnSpecificItem() 
    radTreeViewItemTennis.IsDropAllowed = False 
End Sub
