Try this

protected void Page_Load(object sender, EventArgs e)
        {
            string confirmnumber;
            HiddenField field = (HiddenField)PreviousPage.FindControl("confHidden");
            confirmnumber = field.value;
            Response.Write(confirmnumber);
               
       }

Now I am trying session and the following code. But it is giving an error
"Object reference not set to an instance of object". Please guide me if you have any idea of this.
Thanks

protected void Page_Load(object sender, EventArgs e)
        {
            string confirmnumber = null;
             if (Session["RecordLocator"]!=null)
             confirmnumber = (string)Session["RecordLocator"];
            confirmNoLabel.Text = confirmnumber.ToString();
        }
