C# 在while循环中创建动态图像按钮，并在不使用gridview的情况下触发其事件

我正试图做到以下几点：

访问我的网站内容并从我的数据库中读取主题

在不使用网格视图的情况下动态创建表，并在中动态生成图像按钮 它可以编辑和删除我的内容

我成功地为我的一个图像按钮定义了回发URL，并将其发布到具有我的内容ID的新页面以进行编辑，但我未能定义事件并触发它以在不转到新页面的情况下删除我的内容

这是我的密码：

            CatMsg1.Text = string.Format("{0} عزیز! متاسفانه در برقراری ارتباط با سرور مشکلی پیش آمده، لطفاً این مورد را به مدیریت سایت گزارش کنید", Session["FirstName"]);
        }
    }
}


protected void icd_Click(object sender, EventArgs e)
{
    ImageButton icd = sender as ImageButton;
    CatMessage.Visible = true;
            CatMessage.BorderColor = System.Drawing.ColorTranslator.FromHtml("#930000");
            CatMessage.BackColor = System.Drawing.ColorTranslator.FromHtml("#F4B7B7");
            CatMsg1.Text = string.Format("{0}",icd.ID);
}

我尝试了两种方法

icd.Click+=icd\u Click和
icd.Click+=新图像ClickEventHandler（icd\u Click）触发我的事件，但它根本不起作用
