how to maintain values in gridview even after passing to prev page?

productid	productname	price	quantity
3	watch	400	10

If i click add button , it passes to previous page and add a new record next to the existing row in gridview which is in the nextpage

Page 1 Code

 protected void Button1_Click(object sender, EventArgs e)
    {
        Session["Username"] = "Test1";
        Session["Password"] = "Password";
        Response.Redirect("~/Default2.aspx");
    }
}

Page 2 Code

// Here i assumed that you are showing data from Some DataSource so I have taken Datatable Instead :)

protected void Page_Load(object sender, EventArgs e)
    {
        DataTable dt = new DataTable();
        dt.Columns.Add(new DataColumn("Username"));
        dt.Columns.Add(new DataColumn("Password"));
 
 
        string Username = Session["Username"].ToString();
        string Passsword = Session["Password"].ToString();
 
        if(Username != "" && Passsword != "" )
        {
            //Suppose yourdataGridView is Bounded To Som Datatable  dt 
            //then Add Row to That Dt 
            dt.Rows.Add(Username, Passsword);
            //delete the Content in Session after Adding Row 
            Session["Username"] = "";
            Session["Password"] = "";
 
        }
        GridView1.DataSource = dt;
        DataBind();
 
 
    }

    {
        Session["Username"] = "Test1";
        Session["Password"] = "Password";
