extaspnet中grid全选批量删除的问题
我给grid的pagesize设置为3，然后删除事件的代码如下
 protected void btnDelete_Click(object sender, EventArgs e)
        {
            try
            {
                int m = 0;
                string sql = "Id in (";
                if (Grid1.SelectedRowIndexArray.Length > 0)
                {
                    foreach (int row in Grid1.SelectedRowIndexArray)
                    {
                        if (m > 0)
                        {

                            sql += ",";
                        }
                        sql += Grid1.DataKeys[row][0].ToString();
                        m = m + 1;
                    }

                    sql += ")";
                    
                    if (cbll.Delete(sql))
                    {
                        Grid1.SelectedRowIndexArray = null;
