DataList 编辑时 更新和取消编辑按纽无效,请帮忙看看

Question

只有ItemCommand可以捕捉到命令名称,其他几个事件都捕捉不到命令名称,不知何故ASP.NET 2.0<asp:DataList ID="DataList1" runat="server" Width="100%" DataKeyField="LeavewordsID"

Answer 1

看看你名称是什么是不是update,cancel,delete
 另外看看事件有没有丢失

Answer 2

在datalist中内置了几个commandname分别是
编辑 edit
删除 delete
更新 update
取消 cancel

Answer 3

同意truelove12(这些年来，我走了很多弯路!) 所说.

Answer 4

名称换成这几个都没有用！取消和更新命令没有起到作用！编辑是用ItemCommand

Answer 5

其实不用看DataList里面什么劳什子的commandname了，直接用button触发点击事件即可
如果你要删除前确认的话，就在Page_Load里面加
btnDeleteType.Attributes.Add("onClick","return confirm('你确定要删除所选记录？')");
就可以了
btnDeleteType是你按钮控件的名称
