Question

我在一个页面中有正则表达式验证，它检查文本框中输入的值是否为数字，它不是数字，它给出错误消息“它应该是数字”

但是当我点击表单的下一个按钮时，它会导航到下一页。但它不应该。怎么解决这个问题？

首先......你在web.config中有这个吗？

<xhtmlConformance mode="Legacy">

如果你这样做......这基本上打破了所有客户端验证。请务必注意，服务器端验证不会自动阻止您的页面处理。您必须检查Page.IsValid属性......看起来您正在这样做。但...

第二...为什么你在rfvUserID控件上显式调用Validate（）？这不应该是必要的。这可能是你通过这样做使IsValid属性无效。

但是，听起来自动验证器没有触发。你可以发布aspx吗？只有“Form2”验证组中的验证器才会触发btn_View1_Next。尝试删除所有ValidationGroup设置。它运作正常吗？

最后...... id“Form2”意味着可疑的东西。您在此页面上只有一个实际的表单标签，对吧？否则你会遇到很多问题。

验证失败但转到下一页
