type TreeNodeSelectAction

Member nameDescription

Raises the TreeNodeExpanded event when a node is selected.


Raises no events when a node is selected.


Raises the SelectedNodeChanged event when a node is selected.


Raises both the SelectedNodeChanged and TreeNodeExpanded events when a node is selected.

When the NavigateUrl property for a TreeNode control is set to a value other than an empty string (""), clicking the node navigates to the specified URL. If the NavigateUrl property is set to an empty string, clicking the node causes a postback. The SelectAction property determines the events to raise on the postback. By default, the Select event is raised. No events are raised if the NavigateUrl property is set.


The HoverNodeStyle property is not rendered for a node with its SelectAction property set to the None value.

The following code example demonstrates how to use the TreeNodeSelectAction enumeration to represent the event that is raised when a node is clicked in the TreeView control.
