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;
                 }
             }        }

 添加BarManager和popupMenu组建：

 

 

设置popupMenu组件的Manager属性：

 

 

右键点击popupMenu主键，点击Customize选项添加菜单：

 

 然后便可添加到鼠标事件中，此处以TreeList为例：

2. {   
3. as
4. if
5.             && ModifierKeys == Keys.None   
6.             && treeList1.State == TreeListState.Regular)   
7.     {   
8. new
9.         TreeListHitInfo hitInfo = tree.CalcHitInfo(e.Location);   
10. if
11.         {   
12.             tree.SetFocusedNode(hitInfo.Node);   
13.         }   
14.   
15. if (tree.FocusedNode != null)   
16.         {   
17.             popupMenu1.ShowPopup(p);   
18.         }   
19.     }
