trEEviEw的 mousECliCk 和 noDEmousECliCk 有什么...

http://hi.baidu.com/successjerry/item/239acec67d3d52c0994aa032

额,问题描述...太乱了,不知道在说啥.

点加号,减号的时候,本来就不触发NodeMouseClick事件的..只有当点击Node时,才有可能触发到Node的展开折叠事件.. 代码中添加 e.Cancel可以取消本次NodeMouseClick事件

if(treeview.selectednode.text=="退出系统")

treeView1.NodeMouseDoubleClick += new TreeNodeMouseClickEventHandler(treeView1_NodeMouseDoubleClick); void treeView1_NodeMouseDoubleClick(object sender, TreeNodeMouseClickEventArgs e) { throw new NotImplementedException(); }

TreeView 添加两个事件 void OnTreeNode_NodeMouseClick(object sender, TreeNodeMouseClickEventArgs e) { if (e.Node.Parent != NULL) return;//如果不是根节点,则返回,不执行下面的代码 if (e.Button == MouseButtons.Right) { //右键代码 ...

你在双击事件中只处理子节点就可以了,加个判断 private void treeView1_NodeMouseDoubleClick(object sender, TreeNodeMouseClickEventArgs e) { if (e.Node.Text == "节点1") MessageBox.Show("1"); }

Private Sub TreeView1_NodeMouseClick(ByVal sender As Object, ByVal e As System.Windows.Forms.TreeNodeMouseClickEventArgs) Handles TreeView1.NodeMouseClick If e.Node.Text = "abc" Then '你的代码 End If End SUb

Sub treeView1_NodeMouseClick(ByVal sender As Object, _ ByVal e As TreeNodeMouseClickEventArgs) Handles treeView1.NodeMouseClick textBox1.Text = e.Node.Text End Sub 具体报错在哪里?麻烦贴图

private void Form2_Load(object sender, EventArgs e) { foreach (string dirver in Directory.GetLogicalDrives()) { TreeNode node = new TreeNode(dirver); treeView1.Nodes.Add(node); } treeView1.NodeMouseClick+=new TreeNodeMouseClick...
