推荐答案

听起来像一个已知问题！
在这里查看:两次触发的GridView RowCommand事件 [ ^ ]

有一个简单的解决方案.将buttoncolumn 转换为templatecolumn.然后添加imagebutton:

Sounds like a known issue!
Look here: GridView RowCommand Event Firing Twice [^]

There is a simple solution to it. Convert the buttoncolumn to a templatecolumn. Then add an imagebutton:

<asp:TemplateField ShowHeader="False">
<ItemTemplate>
<asp:ImageButton ID="ImageButton1" runat="server" CommandName="Delete" CommandArgument='<%# Eval("SomeValue") %>'

ImageUrl="~/Images/extras/addtocart.gif" />
</ItemTemplate>
</asp:TemplateField>

在此行命令之后将仅触发一次.

After this Row command would fire only once.

我猜想您的delete函数中有某些原因引起了它.
第二次引发事件时CommandSource的值是什么?

I guess there is something in your delete function which is causing it.
What''s the CommandSource value when the event is raised 2nd time?
