ถามวิธี คลิกบนแถวของ GridView แล้วให้ส่งค่าในคอลัมแรกไปยังอีก Page หนึ่ง

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
        if (e.Row.RowType == DataControlRowType.DataRow)
        {
            e.Row.Attributes["onmouseover"] = "this.style.background = '#CCCCCC';";
            e.Row.Attributes["onmouseout"] = "this.style.background = '#FFFFFF';";
            e.Row.Style["cursor"] = "hand"; 
        }
}
