Thanks for sharing smnbss. It's definitely a pity that it doesn't work and that the ASP.NET team use two different methods to write hidden fields :S

This happen because __VIEWSTATE is rendered inside

Page.BeginFormRender(HtmlTextWriter writer, string formUniqueID)

using the method

this.RenderViewStateFields(writer);

While __SCROLLPOSITIONX/Y are added to the form using

this.ClientScript.RegisterHiddenField("__SCROLLPOSITIONX", this._scrollPositionX.ToString(CultureInfo.InvariantCulture));

this.ClientScript.RegisterHiddenField("__SCROLLPOSITIONY", this._scrollPositionY.ToString(CultureInfo.InvariantCulture));

on the same funcion, so the 2 hidden fields behave in a different way

Sometimes microsoft has the real power to upset me… :)
