The ItemDrag event occurs when the user begins dragging an item. An object specifies which mouse button was pressed.
The following example illustrates the use of when enabling drag-and-drop operations within a TreeView. The Button property determines whether the dragged node should be moved or copied to its destination. The node, represented by the Item property, is then passed to the TreeView control's DoDragDrop method along with a value indicating the desired effect.
For the complete example, see the TreeView.ItemDrag reference topic.
Private Sub treeView1_ItemDrag(ByVal sender As Object, ByVal e As ItemDragEventArgs) ' Move the dragged node when the left mouse button is used. If e.Button = MouseButtons.Left Then DoDragDrop(e.Item, DragDropEffects.Move) ' Copy the dragged node when the right mouse button is used. ElseIf e.Button = MouseButtons.Right Then DoDragDrop(e.Item, DragDropEffects.Copy) End If End Sub 'treeView1_ItemDrag
