方法一: int nodeIndex = 0; bool nodeChanged = false; //右键点击,就进入修改状态 private void treeView1_NodeMouseClick(object sender, TreeNodeMouseClickEventArgs e) { if (e.Button == MouseButtons.Right) { e.Node.BeginEdit(); } } private void treeView1_AfterLabelEdit(object sender, NodeLabelEditEventArgs e) { nodeIndex = e.Node.Index; nodeChanged = true; e.Node.EndEdit(true ); } private void treeView1_NodeMouseHover(object sender, TreeNodeMouseHoverEventArgs e) { if (nodeChanged == true) { //在这里保存数据到数据库 MessageBox.Show(treeView1.Nodes[nodeIndex].Text); nodeChanged = false; } }
方法二:
方法二: MouseClick和AfterLabelEdit的使用,treeView1.LabelEdit = true;这句不可缺少: public Form1() { InitializeComponent(); this.Load+=new EventHandler(Form1_Load); treeView1.MouseClick+=new MouseEventHandler(treeView1_MouseClick); treeView1.AfterLabelEdit+=new NodeLabelEditEventHandler(treeView1_AfterLabelEdit); } private void Form1_Load(object sender, EventArgs e) { for (int i = 0; i < 10; i++) { treeView1.Nodes.Add("tv" + i.ToString()); treeView1.Nodes[i].Nodes.Add("tvc"+i.ToString()); } treeView1.LabelEdit = true;//不可缺少 } private void treeView1_MouseClick(object sender, MouseEventArgs e) { TreeView tv=(TreeView)sender;//获取treeview if (e.Button == MouseButtons.Right)//判断是否鼠标右键 { if (tv.SelectedNode != null)//判断是否存在选择节点 tv.SelectedNode.BeginEdit(); } } private void treeView1_AfterLabelEdit(object sender, NodeLabelEditEventArgs e) { string newTxt = e.Label;//获取新文本 //string id = e.Node.Text;//获取原来的文本 //进行你的更新操作 }
