I tried this but getting javascript error and couldn't get desired result.
Anybody if had done this kind of thing please send the code.
Thanks again in advance.

protected void gdv_QuoSundry_RowDataBound(object sender, GridViewRowEventArgs e)
    {
 if (e.Row.RowType == DataControlRowType.DataRow)
        {
            TextBox TextBox1 = (TextBox)e.Row.FindControl("TextBox1");
            TextBox TextBox2 = (TextBox)e.Row.FindControl("TextBox2");

            if (TextBox1 == null)
            {
                TextBox2.Attributes.Add("onBlur", "changeMe('"+TextBox1.ClientID+  "','"+TextBox2.ClientID+"')");
            }

        }
}

  <script type="text/javascript">
   function changeMe(oPrice,  oSubTotal) {
            var Price = document.getElementById(oPrice).value;
           
            SubTotal = Price * 10;
            document.getElementById(oSubTotal).value = SubTotal;
        }
     </script>
