RadWindow caching page when browser back button hit?

[Srikanth]

I have Page A and Page B. Page A has "RadWindow" panel which show on condition and Page B is the "Thank you page". When user goes from Page A to Page B using submit button. So Page A is cached. When user clicks back button on browser in Page B. users are seeing cached page and it is never hitting to server check validation. So I used below code to remove cache

 

HttpContext.Current.Response.Cache.SetExpires(DateTime.UtcNow.AddDays(-1)) HttpContext.Current.Response.Cache.SetValidUntilExpires(false) HttpContext.Current.Response.Cache.SetRevalidation(HttpCacheRevalidation.AllCaches) HttpContext.Current.Response.Cache.SetCacheability(HttpCacheability.NoCache) HttpContext.Current.Response.Cache.SetNoStore()

If I use above code I page is load blank page (shown below). because it lost data. User doesn't like this page to display. So they don't want to display. Is it possible reload page when we pressed back button? How?

<telerik:RadWindow ID="radMembershipRenewal" Title="Change Membership and Subscription" KeepInScreenBounds="true" VisibleOnPageLoad="false"VisibleStatusbar="False" EnableEmbeddedSkins="False" Modal="true" ReloadOnShow="true"
           Behaviors="Move" runat="server" Height="530" Width="780" >

 

If I dont show RadWindow, I can hit to server for validation. Is there anyway we can handle from RadControls?
