Add RadDatePicker and RadRadioButtonList to the controls supported by RadPersistance  Framework by default:

https://docs.telerik.com/devtools/aspnet-ajax/controls/persistenceframework/getting-started/supported-controls

I want to save the state of a control from the client. My use case can be seen in one of your demos. http://demos.telerik.com/aspnet-ajax/tabstrip/examples/application-scenarios/persisting-tabstrip-settings/defaultcs.aspx?product=persistenceframework

I want to save the selected tab when its been clicked, this way the user does not have to click on some other button or remember to do that.  

I also don't want an OnTabClick event to happen on the server to slow things down.

Currently the persistence framework will not restore the values of a checkbox filter. You may use the attached runnable demo as an example. 

When saving a RadTabStrip, the RadPersistenceFramework should save the order of the tabs.  This will allow users to save their preferred tab order when the RadTabStrip property EnableDragToReorder is enabled.  See the following forum post from July 2014 concerning this:  http://www.telerik.com/forums/radpersistencemanager-and-reordered-radtabstrip-tabs

I would like to see support for RadMonthYearPicker in the Persistence Framework

RadGrid aggregates are not persisted by Persistence Framework

#843691

RadPersistenceFramework stores some of the RadPivotGrid/RadGrid settings using fully qualified DLL name which causes a problem when loading them in a project using a newer version of the Telerik.Web.UI assembly.

In case where a user tries to load persisted settings of RadTileList on initial load (!IsPostBack) the RadTileList is not initialized correctly

Reproduced on the online demo with AllowMultiColumnSorting enabled on the MasterTableView.
