我使用时出现一个奇怪的问题： - 一个用户控件（包含一组带有常规asp.net验证器的文本框），其中validationgroup =“vg_save” - 以及在此usercontrol外部带有验证组“vg_save”的按钮，这两个按钮都位于asp.net页面的updatepanel中。
当我点击按钮时，它会回发到服务器然后激活验证器。
为什么会回发到服务器
以下是我的.ASPX文件

您需要在验证程序上启用客户端验证
您可以使用验证程序的EnableClientScript属性
您可以在此处找到有关此属性的信息： http://msdn.microsoft.com/en-us/library/system.web.ui.webcontrols.basevalidator.enableclientscript(v=vs.110).aspx
答案 1 :(得分：1)
当OnClientClick表达式的计算结果为true时，页面将被提交。
在您的函数中调用Page_ClientValidate，以便在返回true之前检查页面的验证
