以下代码来自详细信息页面，该页面从另一个页面接收查询字符串，然后根据传递的ID加载详细信息。这工作正常，但现在我的问题是保存更改按钮似乎没有做它应该是什么;页面只是像它提交的那样闪烁并加载所有的值，我已经调试了，这一切都很顺利，可能是什么问题？它可能与我使用查询字符串有关，因为我在另一个页面上有另一个更新命令（没有查询字符串），它完美地运行...

您的按钮点击事件处理程序SaveCustomerChanges_Click将在您的Page_Load事件处理程序之后发生。您的页面加载事件处理程序正在加载您的UI。在UI已加载后，您正在更新数据。您需要在执行更新后重新加载UI（想想“DataBind”）。
