Values stored in ViewState work differently than session. Unlike Session, a value stored in ViewState of one page cannot be retrieved from another. Actually ViewState is nothing but a system managed hidden encrypted field in the markup produced. How do you save a value in ViewState? like this:

ViewState["MyValue"]=GrideView1.SelectedValue.ToString();

Later you can retrieve that value like this

if(ViewState["MyValue"]!=null)
{
     Response.Redirect("SecondPage.aspx?param="+ViewState["MyValue"]);
}
