以下两种方法哪个不报错就用哪个.用法都是在TreeView标签中加入OnClick="",然后引入函数名即可 第一种方法:(摘自:http://www.cnblogs.com/freeliver54/archive/2007/09/04/881024.html) <script type ="text/javascript" > function postBackByObject() { var o = window.
treeview.nodes是获取下一级所有子节点,但是如果是多层的话,就不能,想个法子来获取所有的节点(含节点的子节点),想了想 还是替归算法比较方便,如是有了下面的代码 public static List<TreeNode> getAllNodes(TreeNodeCollection node) { List<TreeNode> lst = new List<TreeNode>(); foreach (TreeNode n in node) { if (!lst
生成ContextMenuStrip var docMenu = new ContextMenuStrip(); ToolStripMenuItem deleteMenuItem = new ToolStripMenuItem(); deleteMenuItem.Text = "Delete"; deleteMenuItem.Click += new EventHandler(deleteMenuItem_Click); //给添加的ContextMenuStrip绑定click事件
