我正在尝试从gridview的rowcommand更新更新面板中的文本框的值，也在更新面板中。 rowcommand正在触发更新面板并运行OnRowCommand代码，但是文本框的值根本没有更新。
我没有收到任何错误，我已经检查过我不是通过跟踪我提供值的类的值来输入空字符串。
这是我的代码：

我最终想到了这一点。似乎如果将CommandName命名为“Edit”，它会调用'OnRowEditing'函数，该函数未定义。因此，我只是将CommandName重命名为“EditExpenses”。我也为删除命令做了同样的事。

请将UpdatePanel的UpdateMode设置为Always以查看这是否有所不同。有关UpdatePanel内容更新时的规则和条件，请参阅备注：http://msdn.microsoft.com/en-us/library/system.web.ui.updatepanel.updatemode(v=vs.110).aspx
