Asp.net listview_onitemcommand未启动

我的代码是

protected void ListView2_OnItemCommand(object sender, ListViewCommandEventArgs e)
{
    if (String.Equals(e.CommandName, "forallow"))
    {

        string[] commandArgs = e.CommandArgument.ToString().Split(new char[] { ',' });
        string scrapid = commandArgs[0];
        string uid = commandArgs[1];
        string imgname = commandArgs[2];
        int cat = Convert.ToInt32(scrapid);
        int sho = Convert.ToInt32(uid);

        string query2 = "update request set status='allow' where request_id='" + cat + "'and shop_id=" + sho + ";update advertisement set imagename='" + imgname + "',shop_id='" + sho + "' where adver_id=" + cat;
        cmd = new SqlCommand(query2, connection);
        cmd.Connection.Open();
        int rows = cmd.ExecuteNonQuery();
        if (rows > 0)
        {
            Response.Write(@"<script language='javascript'>alert('permission granted');</script>");
        }
        cmd.Connection.Close();
        string msgg = "insert into messages(message,shop_id) values('Permission is granted for category id ''" + cat + "' ,'" + sho + "')";
        cmd = new SqlCommand(msgg, connection);
        cmd.Connection.Open();
        cmd.ExecuteNonQuery();
        cmd.Connection.Close();
        productfill();

    }


}

受保护的无效ListView2\u OnItemCommand（对象发送方，ListViewCommandEventArgs e）
{
if（String.Equals（例如CommandName，“forallow”））
{
string[]commandArgs=e.CommandArgument.ToString（）.Split（新字符[]{'，}）；
字符串scrapid=commandArgs[0]；
字符串uid=commandArgs[1]；
字符串imgname=commandArgs[2]；
int cat=Convert.ToInt32（scrapid）；
int sho=转换为32（uid）；
string query2=“更新请求集状态='allow'其中请求id=”+cat+”，商店id=“+sho+”；更新广告集imagename=”+imgname+”，商店id=“+sho+”，其中adver\U id=“+cat；
cmd=新的SqlCommand（query2，连接）；
cmd.Connection.Open（）；

如果（行数>0）

响应。写入（@“警报（‘已授予权限’）；”）；
