Solution 1

You shouldn't use ViewState because you're navigating between different pages. Use Session instead.

Solution 3

i agree with Jim

try in this way

On Click Of btnPreview
session["Name"]=Convert.tostring(txt.text);

Redirect to nextPage 

//do your work 

Redirect to previous Page 

//in the Page Load Check 

if(session["Name"]!=null)
TextBox1.text = Session["Name"];
//clear that Session 

Session["Name"]=null;
Session.clear();

array.Add(txtASO.Text);
array.Add(txtController.Text);
array.Add(txtGPS.Text);
array.Add(txtTAP.Text);

Session["ArrayList"] = array;
Response.Redirect("~/Preview.aspx");

THen the page is redirected to Preview Page.
On Preview Page

on Page Load
ArrayList array1 = new ArrayList();
array1 = (ArrayList)Session["ArrayList"];
lblAD.Text = Convert.ToString(array1[0]);
lblASO.Text = Convert.ToString(array1[1]);
lblController.Text = Convert.ToString(array1[2]);
lblGPS.Text = Convert.ToString(array1[3]);
lblTAP.Text = Convert.ToString(array1[4]);

as Prerak has suggest .You can take one simple html input tag type = button

<input type="button" value="Back to Previous Page" önClick="javascript: history.go(-1);"/>

and call javascript: history.go(-1); this function it will help you
