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
