Yes.
View state is page specific; it contains information about
controls embedded on theparticular page. ASP.NET 2.0
resolves this by embedding a hidden input field
name,__POSTBACK . This field is embedded only when there is
an IButtonControl on thepage and its PostBackUrl property is
set to a non-null value. This field contains the viewstate
information of the poster page. To access the view state of
the poster page, you canuse the new PreviousPage property of
the page

Page poster = this.PreviousPage;

Then you can find any control from the previous page and
read its state

Label posterLabel =(Label)poster.findControl("myLabel");
string lbl = posterLabel.Text;

This cross-page post back feature also solves the problem of
posting a Form to multiplepages, because each control, in
theory, can point to different post back URL.
