ASP.Net Validators在使用usercontrols后回发后被触发

时间：2014-12-26 19:41:05

标签： c# asp.net user-controls

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

更新面板包含用户控件和验证用户控件文本框的按钮

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

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
