ListView右击菜单问题

[Mo_DeNo]

winform做的小程序，在程序载入的时候，会读取数据库的数据来创建根节点和子节点。设计时，为treeview添加了NodeMouseClick事件，并判断是右击时，显示ContextMemuScript。在右击菜单中有个添加节点的功能。以上说的功能都能实现。但是如果我用右击菜单中的添加节点来添加一个根节点，这时候右击这个节点，菜单是不会显示的，但是debug的话，能跑到NodeMouseClick事件里。感觉很是困惑。

这个是右击事件

private void tvTable_NodeMouseClick(object sender, TreeNodeMouseClickEventArgs e)
        {
            if (e.Button == MouseButtons.Right)
            {                
                cmsNodeRightMemu = new ContextMenuStrip();

               // Point ptMemuPosition =PointToScreen( new Point(e.Node.Bounds.X + e.Node.Bounds.Width, e.Node.Bounds.Y ));

                cmsNodeRightMemu.TopLevel = true;
                cmsNodeRightMemu.Show(tvTable,e.X,e.Y);
            }
        }

这个是添加节点事件

private void bbbbToolStripMenuItem_Click(object sender, EventArgs e)
        {
            bool hasSameNode = false;

            string strRootNodeName = string.Empty, strSelectNode = string.Empty;
            int intSelectNodeLevel = -1;

            intSelectNodeLevel = tvTable.SelectedNode.Level;

            strSelectNode = intSelectNodeLevel == 0 ? "Root" : "Sub";

            strRootNodeName = Interaction.InputBox("Please Input " + strSelectNode + " Node", "Add", "New", -1, -1);
            hasSameNode = ExistsSameNodeInSameLevel(strRootNodeName, intSelectNodeLevel, tvTable.SelectedNode.Parent);

            while (hasSameNode)
            {
                MessageBox.Show("Has Same Node");

                strRootNodeName = Interaction.InputBox("Please Input " + strSelectNode + " Node", "Add", "New", -1, -1);
                hasSameNode = ExistsSameNodeInSameLevel(strRootNodeName, intSelectNodeLevel, tvTable.SelectedNode.Parent);
            }

            TreeNode trAddedNode, trSubNode;

            if (intSelectNodeLevel == 0)
            {
                trSubNode = new TreeNode("NewChildNode");
                trSubNode.Tag = intAddNodeMaster;
                trSubNode.Name = "NewChildNode";
                trSubNode.ContextMenuStrip = cmsNodeRightMemu;

                trAddedNode = new TreeNode(strRootNodeName, new TreeNode[] {trSubNode });
                trAddedNode.Name = strRootNodeName;
                trAddedNode.ContextMenuStrip = cmsNodeRightMemu;

                tvTable.Nodes.Add(trAddedNode);
            }
            else
            {
                trAddedNode = new TreeNode(strRootNodeName);
                trAddedNode.Tag = intAddNodeMaster;
                trAddedNode.Name = strRootNodeName;
                trAddedNode.ContextMenuStrip = cmsNodeRightMemu;
                tvTable.SelectedNode.Nodes.Add(trAddedNode);
            }
        }

好吧，我自己搞定了，一开始的时候不要new就行了
