The text of a node in the 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 property to a value other than an empty string (""). To put a node into selection mode, set the node's 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 event. You can optionally specify a different event to raise by setting the node's SelectAction property. For more information, see . To determine which node was clicked in selection mode, use the property of the control.
