Asp.net GridView页脚中的按钮未触发

单击GridViews页脚中的“我的按钮”时未触发。没有错误，没有代码被执行，它所做的只是一次刷新，页面上的所有内容都与单击按钮之前完全相同。调试甚至不执行

根据正常情况声明代码隐藏

还有按钮

                        </asp:TemplateField>

有人看到什么不对劲吗

ASPX文件更新

选择年份

看了之后，我有两个可能的建议给你-

1） 检查绑定网格视图的位置-

它应该在里面！IsPostBack

例如：

2） 您是否在某个地方禁用了ViewState

编辑-问题已解决

在asp:GridView中，需要一个onrow命令来触发codebehind中的命令。将其添加到.aspx页面中的asp:gridview标记中

---

onrowcommand=“dgvretail\u RowCommand”

您好。添加了数据绑定，但它不起作用。做完全相同的事情。我不记得禁用了视图状态..我不这么认为。它实际上并没有做任何事情，就像一个没有代码的死按钮。我似乎找不到它是什么。@NikosV您可以更新.aspx页面或视图，以便我可以看到网格视图的onrow命令吗？（基本上，您正在进行的调用是为了触发dgvretailu RowCommand）@NikosV，正如我提到的.aspx页面内容，其中有网格视图。在文章中，您只在网格视图中包含了控件。我想
