Get Only Current Page Data From ASP.NET Gridview

Sometimes we want to get current page data from gridview. In my case, I want to update current view data as read. Here is the code:


private void UpdateAsRead()
    {
        //get header
        foreach (DataControlField col in gvForm.Columns)
        {
            //Response.Write(col.HeaderText);
        }
        //get data
        foreach (GridViewRow row in gvForm.Rows)
        {
            int i = 1;
            foreach (TableCell cell in row.Cells)
            {
                //get all rows
                if (i == 1)
                {
                    GeneralDao gen = new GeneralDao();
                    //Response.Write(cell.Text + "
");
                    string strSQL = @"UPDATE TMIForm SET ldate ='" + gen.GetDateTime() + @"', luserid='" + GetUsername + @"'
                                        WHERE id = '" + cell.Text + @"'";
                    frmDao.Update(strSQL);
                }
                i += i;

                if (i == 7) { i = 1; }

            }
