Repeater中OnItemCommand与OnItemDataBound事件的使用

<td><asp:Button ID="lb" runat="server" Text="停 电" CommandName="edit" CommandArgument='<%#Bind("KGN") %>'></asp:Button>

  protected void Rp_OnItemCommand(object sender, System.Web.UI.WebControls.RepeaterCommandEventArgs e)
        {
            if (e.CommandName == "edit")
            {
                string[] sql=new string[2];
                string kgNumber = Convert.ToString(e.CommandArgument);
                sql[0] = "update Sys_PreBuy_KG set kg0=0,kg1=0,kg2=0,kg3=0,kg4=0,kg5=0,kg6=0,kg7=0,kg8=0,kg9=0,kg10=0,kg11=0,kg12=0,kg13=0,kg14=0,kg15=0 where userid='" + mTerminalID + "'";
                sql[1] = "update Sys_PreBuy_KG set " + kgNumber + "=1 where userid='" + mTerminalID + "'";
                DbConnect.Instance.ExecSQL(sql, mDbFlag);
                GetDetailInfo();
            }
        }
        protected void Rp_OnItemDataBound(object sender, System.Web.UI.WebControls.RepeaterItemEventArgs e)
        {
            if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
            {
                DataRowView   drv   =   e.Item.DataItem   as   DataRowView;
                string kgNumber = drv[2].ToString();
