Asp.NET Webforms register.aspx验证

Question

我正在开发一个使用Visual Studio 2017的自定义网站。我已经包含了Identity，因此有一些提供的页面用于注册或登录用户。我正在修改注册页面以允许使用fileupload控件上传图片（我创建了一个配置文件表，这将保存我想要捕获的额外数据）。但是，当我这样做时，即使电子邮件文本框中有数据，我提交时也会触发电子邮件验证。我认为这可能与上传功能发生时页面重新加载的方式有关？我还想添加一个复选框并显示其他字段（如果选中），使用CheckedChanged事件来设置我想要隐藏的控件的Visible属性。我已经看到，如果我想这样做，我需要将AutoPostBack设置为true。 代码在register.aspx

<asp:Content runat="server" ID="BodyContent" ContentPlaceHolderID="MainContent">
