Returns the selected node within the ASPxTreeView control on the client side.

Declaration

GetSelectedNode(): ASPxClientTreeViewNode

Returns

Type	Description
ASPxClientTreeViewNode	An ASPxClientTreeViewNode object that represents the selected node.

Remarks

If the ASPxTreeView.AllowSelectNode property is set to true, end-users are allowed to select nodes via mouse clicks. The selected node can be obtained on the client side by using the GetSelectedNode method. If there isn’t a selected node within a ASPxTreeView or selection is prohibited, the GetSelectedNode method returns null. In order to select a specific node on the client side, use the ASPxTreeView’s ASPxClientTreeView.SetSelectedNode method.

To learn more see the Selection topic.

The code example below shows how you can change a node’s text on the client side.
