左边一个树 右边一俄iframe 点击节点总是在新窗口打开 如何在iframe中打开呢？
我在treeview的target的属性设为iframe，还是不行。
如：http://authors.aspalliance.com/shark/articles/TreeView/DocTree.aspx请各位大侠帮我一下，找了很多，没有找到满意的。
谢谢大家！

如：<iframe id="ifr" src="..."></iframe>
然后你就把节点的target属性设置为ifr就行了
设置 name 属性TreeNode.Target = "MyFrmName";<iframe name="MyFrmName" ....
在哪设置呀，没有这属性呀晓风大哥

这里的nodeTemp.nodes有错误，提示："nodes" 不是 "System.Web.UI.WebControls.TreeNode" 的成员
我应该怎么处理
谢谢大家关注.
