How to access ViewState value in Other Page
It is now posible form the .net 2.0(2005 version).

u just use/Set the "previouspage" property in the which page u wanted .
example (form 1 u have the "testbox1"

u want to access the value of textbox1 from default1.aspx"

so now u u open default2.aspx

in the code behind just set the following code

page obj=this.previouspage;
testbox txtobj=obj.findcontrol("textbox1");// here u get the data from page1 to page2
string str=txtobj.text;
