DevExpress 给TreeList添加右键菜单

只有在右击节点时才会触发

private void treeList1_MouseDown(object sender, MouseEventArgs e)

         {         

 

           if (e.Button == MouseButtons.Right)

             {

                 treeList1.ContextMenuStrip = null;

 

                TreeListHitInfo hInfo = treeList1.CalcHitInfo(new Point(e.X, e.Y));

                 TreeListNode node = hInfo.Node;

                 treeList1.FocusedNode = node;

                 if (node!=null)

                 {

                     treeList1.ContextMenuStrip = contextMenuStrip1;

                 }

             }

 

        }
