By default, our Focused Node feature is disabled. To enable it, set the
SettingsBehavior.AllowFocusedNode property to true. The focused node's appearance can be specified using the style settings provided by the Styles.FocusedNode property. This demo shows how to dynamically display a focused message's text outside the ASPxTreeList. The Client-Side FocusedNodeChaged event is handled to query the server to return the focused message's Text.
This value is returned by the Result property within the CustomDataCallback event handler, and
specifies the value for the corresponding HTML element. Server-Side API A focused node is identified by the FocusedNode property. To move node focus in code, use the node's
Focus() method. In this demo, this method is called when the page is being loaded to focus an unread message. Client-Side API End-users move node focus by clicking nodes they desire. To respond to changing node focus, handle the Client-Side
FocusedNodeChanged event. To identify a node currently being focused, use the Client-Side GetFocusedNodeKey() method.
To move node focus, use the SetFocusedNodeKey() method. To learn more, please see the ASPxTreList's help documentation.
