Question

How could I access the ViewState of the current page using HttpContext

I have a ViewStateUtil class that I’d need to implement:

    public static T GetViewState<T>(ViewStateKey viewStateKey)
    {
       // how to implement it?! HttpContext.Current...?
    }

Answer 1

    private static T GetViewState<T>(string name)
    {
        return (T) ((BasePage)HttpContext.Current.CurrentHandler).PageViewState[name];
    }

I added a new PageViewState property and let all my pages inherit from my BasePage to expose ViewState then being able to get or set it.
