如何设置treeview中的treenode不能被点击？

[icemanpro]

在asp.net中，有一treeview，其treenode都是动态生成的，这些生成的treenode都有连接，能被点击。现在想要其中部分treenode不能被点击，请问如何编写？

既然你的Node是绑定的,应该有个 Enable 设置他的False True

[回.到.未来]

让treenode的navigateurl=""就可以

node无enable属性。

设treenode的navigateurl=""后，node还是能被点击。

设置SelectAction=TreeNodeSelectAction.None

或者

不想被点击，那就不要显示出来

[faib920]

navigateurl = "javascript:;";

[esh120706]

Node.SelectAction = TreeNodeSelectAction.None;

[esh120706]

Node.SelectAction = TreeNodeSelectAction.None;
