Saving the viewstate of RadControls server-side

HOW-TO

Save the viewstate of RadControls server-side

SOLUTION 

We use a common approach to store our RadControls ViewState and you shouldn't have any problems storing it on the server (when the EnableViewState property for the page in which the control(s) reside is set to True). Our products can also work with custom ViewStateManager classes - just keep in mind that the .aspx web form in which the control(s) is(are) placed should extend from the BasePage class,
e.g.

public class WebForm1 : BasePage

and you should place the following lines in your web-application Web.config file:

Attached is a small demo project illustrating this approach.
