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

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
