使用用戶控件時在回發后觸發ASP.Net驗證程序

Question

我在使用時出現一個奇怪的問題：-一個帶有validationgroup =“ vg_save”的用戶控件（包含一組帶有常規asp.net驗證器的文本框）-和一個帶有validationgroup“ vg_save”的按鈕在此用戶控件之外，並且兩者都是在asp.net頁面的updatepanel中。

當我單擊該按鈕時，它將回發到服務器，然后觸發驗證程序。

為什么發生此回發到服務器

這是我的.ASPX文件

更新面板包含用戶控件和用於驗證用戶控件文本框的按鈕

Answer 1

您需要在驗證器上啟用客戶端驗證

您可以使用驗證器的EnableClientScript屬性

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

Answer 2

當OnClientClick表達式的值為真時，將提交頁面。

在函數中調用Page_ClientValidate，以便在返回true之前檢查頁面的有效性
