An ASPx |
#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.
