现在imagebutton3_click事件无法实现！！！请问，大虾们，我该怎么做呢！！！

Answer 1

应该是OnClick=“ImageButton3_Click”

Answer 2

这个简单，你设置下image的CommandName属性，然后在ItemCommand事件里
protected void DataList1_ItemCommand(object source, DataListCommandEventArgs e)
    {
        if (e.Item.ItemType == ListItemType.AlternatingItem || e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.EditItem)
        {
                        switch (e.CommandName)
            {
                case "cancel":
                    dalbcq.Update(bcid, "noo");
                    p1.Visible = false;
                    break;
                case "ok":
                    Add(bcid,cqid,fck.Value);
                    p1.Visible = false;
                    BindBc(cqid);
                    break;
                default:
                    break;
            }
        }
    }
