Assembly: DevExpress.Web.ASPxTreeList.v20.2.dll

NuGet Package: DevExpress.Web

Declaration

[DefaultValue(false)]
public bool ProcessFocusedNodeChangedOnServer { get; set; }

Property Value

Type	Default	Description
Boolean	**false**	true to process the event on the server side; false to completely handle it on the client side.

Property Paths

You can access this nested property as listed below:

Library	Object Type	Path to ProcessFocusedNodeChangedOnServer
ASP.NET Controls and MVC Extensions	ASPxTreeList	.SettingsBehavior .ProcessFocusedNodeChangedOnServer
ASP.NET MVC Extensions	MVCxTreeList	.SettingsBehavior .ProcessFocusedNodeChangedOnServer
	TreeListSettings	.SettingsBehavior .ProcessFocusedNodeChangedOnServer
	TreeListSettings<RowType>	.SettingsBehavior .ProcessFocusedNodeChangedOnServer

Remarks

If the 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 ASPxTreeList.FocusedNodeChanged event is fired, which if handled, allows any desired server-side action to be performed.
