About RadPersistenceFramework for ASP.NET AJAX

Telerik’s Persistence Framework provides the ability to preserve and restore the state of UI for ASP.NET AJAX, which gives your end users the freedom to arrange and use your app in a way most convenient to them. The framework mainly saves and loads settings of the Telerik controls which are UI configurable, e.g. RadTreeView’s expanded, checked and selected state. The core functionality is presented by RadPersisterManager and RadPersisterManagerProxy – there should be only one instance of the RadPersistenceManager and the proxies are defined on the content pages or user controls to persists the state of the controls on them. RadPersistenceManager allows you to save and load custom key-value settings.

RadPersistenceFramework and 120+ other controls are part of UI for ASP.NET AJAX, a comprehensive toolset taking care of the common functionality of your application, while leaving you with more time to work on its business logic.
