本文详细介绍了ASP.NET中TreeView控件的工作模式，包括选择模式和导航模式的区别。通过设置NavigateUrl属性，可以切换节点的显示模式。默认情况下，点击选择模式的节点会触发页面回发并引发SelectedNodeChanged事件。文章还提到了如何使用SelectAction属性来指定不同的事件，以及如何通过TreeView的SelectedNode属性确定被点击的节点。

The text of a node in the TreeView control can be in one of two modes: selection mode or navigation mode. By default, a node is in selection mode. To put a node into navigation mode, set the node's NavigateUrl property to a value other than an empty string (""). To put a node into selection mode, set the node's NavigateUrl property to an empty string.

By default, clicking a node that is in selection mode posts the page back to the server and raises the SelectedNodeChanged event. You can optionally specify a different event to raise by setting the node's SelectAction property. For more information, see SelectAction. To determine which node was clicked in selection mode, use the SelectedNode property of the TreeView control.
