VIEWSTATE - LoadPageStateFromPersistenceMedium problem

[Dominik Lisowski]

I want to remember ViewState, go to another page then come back and load
remembered ViewState.

I’ve used this:
Listing 3: ViewState Saved in Session State

protected override object LoadPageStateFromPersistenceMedium() {
return Session["ViewState"];
}

protected override void SavePageStateToPersistenceMedium(object viewState) {
Session["ViewState"] = viewState;
// Bug requires Hidden Form Field __VIEWSTATE
RegisterHiddenField("__VIEWSTATE", "");
}

Everything works great EXCEPT CHECKBOXes and RADIOBUTTONS CHECKED property!
It’s always CHECKED = FALSE (even if in designer I defined it to be TRUE)…

What do I do wrong?

Thanks for any help
