ValidationSummary不顯示

Question

我有一些驗證控件和驗證摘要。 用戶離開文本框進行驗證後，客戶端驗證顯示出來。 服務器端驗證顯示從未啓動。 驗證摘要顯示永不起作用。

我做錯了什麼？

    public void IsUsernameFree(object source, ServerValidateEventArgs value) 
    { 
     string username = value.Value; 
     DAL.User user = DAL.UserHandling.GetUserByName(username); 
     value.IsValid = (user == null); 
    } 

    public void IsAGBChecked(object source, ServerValidateEventArgs value) 
    { 
     value.IsValid = (chkRegsiterAGBs.Checked); 
    }

無法確定從查看已發佈的代碼，但您是否在任何地方檢查Page的IsValid屬性？例如。在運行任何其他方法之前？

if (Page.IsValid){ 

    //Do additional processing 
    //register user etc. 
} 

此檢查將強制執行頁面上的所有驗證控件，然後應該觸發顯示驗證錯誤。

編輯：

您需要的的ValidationGroup在您的標記設置爲「註冊」定義linkRegister控制

`<asp:LinkButton CausesValidation="true" ID="linkRegister" CssClass="linkWhite" runat="server" OnClick="linkRegister_Click" ValidationGroup="Register">Jetzt Registrieren</asp:LinkButton>` 

而且，你的密碼的RegularExpressionValidator都需要有ValidationExpression屬性的設置標記：

`<asp:RegularExpressionValidator ValidationGroup="Register" 
    CssClass="validator" ControlToValidate="txtRegisterPW1" 
    ID="valPasswordLenght" runat="server" ErrorMessage="Das Passwort 
    muss mindestens 6 Zeichen haben." Validationexpression="[\w+\d+]{6,}" 
</asp:RegularExpressionValidator>`
