ASPxTreeList.FocusedNodeChanged Event

Fires after the focused node has been changed.

Namespace: DevExpress.Web.ASPxTreeList

Assembly: DevExpress.Web.ASPxTreeList.v23.2.dll

NuGet Package: DevExpress.Web

Declaration

C#

public event EventHandler FocusedNodeChanged

VB.NET

Public Event FocusedNodeChanged As EventHandler

Event Data

The FocusedNodeChanged event's data class is EventArgs.

Remarks

The FocusedNodeChanged event is raised when an end-user moves focus from one node to another.

If the TreeListSettingsBehavior.ProcessFocusedNodeChangedOnServer property is set to false, the ASPxClientTreeList.FocusedNodeChanged event is handled on the client side without a callback to the server. Setting this property to true indicates that the final processing of the event should be performed on the server side, and so a round trip to the server is required. During such a round trip the corresponding server-side FocusedNodeChanged event is fired, which if handled, allows any desired server-side action to be performed.
