ASPxTreeList.SelectionChanged Event
Fires after the selection has been changed.
Namespace: DevExpress.Web.ASPxTreeList
Assembly: DevExpress.Web.ASPxTreeList.v18.2.dll
Declaration
Event Data
The SelectionChanged event's data class is EventArgs.
Remarks
The ASPxTreeList allows multiple nodes to be selected. End-users can select/deselect nodes via selection cells. Nodes can also be selected/deselected in code using the methods provided by the ASPxTreeList control. Handle the ASPxTreeList.SelectionChanged event to respond to a selection change.
If the TreeListSettingsBehavior.ProcessSelectionChangedOnServer property is set to false, the ASPxClientTreeList.SelectionChanged event is handled on the client side without a postback 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. As a result, the SelectionChanged event is raised.
