Namespace: DevExpress.Web

Assembly: DevExpress.Web.v22.1.dll


public string SaveStateToCookiesID { get; set; }

Property Value

Type Default Description
String String.Empty

A string value specifying a cookie’s name.


This property is in effect if the ASPxTreeView.SaveStateToCookies property is set to true.

The SaveStateToCookiesID property allows you to control the manner in which the ASPxTreeView control’s state information is persisted in cookies. If this property is set to an empty string (the default value), the name of the cookie which will store the control’s state is composed automatically, based upon the page name and the ASPxTreeView control’s identifier. In this case, such a cookie is tightly linked with the requested page and the corresponding ASPxTreeView control. In some cases however, it may be required that a ASPxTreeView control’s state information can be shared between different requested pages, for instance, when a ASPxTreeView control is placed on a master page and its state needs to be kept while displaying different content pages. In this case, you can assign any specific identification name to the SaveStateToCookiesID property, and if this name is independent from the page name and the ASPxTreeView control’s identificator, the state information stored by the cookie can be applied to all the ASPxTreeView controls (on all the web pages) whose SaveStateToCookiesID property is set to the same value.


Refer to the RFC 2965 - Section 4.1.1 Syntax document to learn about characters allowed in cookies.
