asp.net用TreeView后台动态生成节点，怎么实现点击节点就在有框架中打开相应页面
页面中有左右两个框架，左边是显示菜单，我用TreeView在后台添加节点，那要怎么实现我上面标题讲的那样。或者说在后台怎么给节点添加点击事件，触发脚本。...

如果右边的框架名为:view frame name='view'
那么在动态生成节点时如下设置就可以实现:
TreeNode node = new TreeNode();
node.Text = "节点名";
node.NavigateUrl = "页面地址";
node.Target = "view";//框架名
this.TreeView1.Nodes.Add(node);

TreeNode node = new TreeNode();
node.Text = "节点名";
node.NavigateUrl = "页面地址";
node.Target = "view";//框架名
this.TreeView1.Nodes.Add(node);

我做的可能比较复杂,简而言之就是生成静态html页面的过程中给节点添加对应的href链接地址，希望对你有帮助！
