使用用户控件时在回发后触发ASP.Net验证程序

Question

我在使用时出现一个奇怪的问题：-一个带有validationgroup =“ vg_save”的用户控件（包含一组带有常规asp.net验证器的文本框）-和一个带有validationgroup“ vg_save”的按钮在此用户控件之外，并且两者都是在asp.net页面的updatepanel中。

当我单击该按钮时，它将回发到服务器，然后触发验证程序。

为什么发生此回发到服务器

这是我的.ASPX文件

更新面板包含用户控件和用于验证用户控件文本框的按钮

Answer 1

您需要在验证器上启用客户端验证

您可以使用验证器的EnableClientScript属性

您可以在以下位置找到有关此属性的信息： http : //msdn.microsoft.com/zh-cn/library/system.web.ui.webcontrols.basevalidator.enableclientscript(v=vs.110).aspx

Answer 2

当OnClientClick表达式的值为真时，将提交页面。

在函数中调用Page_ClientValidate，以便在返回true之前检查页面的有效性
