protected void Button1_Click(object sender, EventArgs e)
    {
        for (int i = 0; i < GridView1.Rows.Count; i++)
        {
           TextBox t1 = (TextBox)GridView1.Rows[i].FindControl("tt1");
           TextBox t2 = (TextBox)GridView1.Rows[i].FindControl("tt2");
           if(t1 != null)
           t1.Text = TextBox1.Text;
           if (t2 != null)
