我停止执行并返回可能保留数据的同一页面 [英] I stop execution and return to the same page possible keeping the data

问题描述

我正在为公司开发一些东西，用户必须使用公司的电子邮件地址进行注册。 [e-mail]



我使用默认的asp.net 2012账户注册。



我希望当用户将信息放入文本框id = username时，如果它不包含@ Company.lc向他们发送消息告诉他们使用正确的电子邮件地址

并给他们改变它的机会。



目前显示消息但继续继续执行。



我尝试了什么：

I am developing something for a company and the user must register using the company's email address. "[e-mail]"

I am using the default asp.net 2012 Account Registration.

I want when the user put information in the textbox id=username, that if it does not contain @Company.lc to send a message to them telling to use the correct email address
and give them the oppunitity to change it.

At present it shows the message but continue continue executing.

What I have tried:

<WizardSteps>
           <asp:CreateUserWizardStep runat="server" ID="RegisterUserWizardStep">
               <ContentTemplate>


                   <p class="message-info">
                       Passwords are required to be a minimum of <%: Membership.MinRequiredPasswordLength %> characters in length.
                   </p>

                   <p class="validation-summary-errors">
                       <asp:Literal runat="server" ID="ErrorMessage" />
                   </p>

                   <fieldset>

推荐答案

CreatedUser 事件触发之后用户已创建。拒绝无效的用户名为时已晚。



你可以使用 CreatingUser 事件验证新用户名，并设置 e.Cancel = true 如果它无效。



但是，使用 RegularExpressionValidator <会更加清晰/ a> [ ^ ]来验证输入：

The CreatedUser event fires after the user has been created. That is too late to reject an invalid username.

You could use the CreatingUser event to validate the new username, and set e.Cancel = true if it's not valid.

However, it would be far cleaner to use the RegularExpressionValidator[^] to validate the input:

<li>
    <asp:Label runat="server" AssociatedControlID="UserName">User name</asp:Label>
    <asp:TextBox runat="server" ID="UserName" />
    <asp:RequiredFieldValidator runat="server" 
        ControlToValidate="UserName"
        CssClass="field-validation-error" 
        ErrorMessage="The user name field is required." 
    />
    <asp:RegularExpressionValidator runat="server"
        ControlToValidate="UserName"
        CssClass="field-validation-error"
        ErrorMessage="Please use your company email ending @company.lc"
        ValidationExpression="^[^@]+@company\.lc

/>
< / li>

" /> </li>

protected void RegisterUser_CreatedUser(object sender, EventArgs e)
{
    if (Page.IsValid)
    {
        FormsAuthentication.SetAuthCookie(RegisterUser.UserName, createPersistentCookie: false);
        MembershipUser newUser = Membership.GetUser(RegisterUser.UserName);
        SendEmail();
        
        string continueUrl = RegisterUser.ContinueDestinationPageUrl;
        if (!OpenAuth.IsLocalUrl(continueUrl))
        {
            continueUrl = "~/";
        }
        
        Response.Redirect(continueUrl);
    }
}

Regexper： ^ [^ @] + @ company\.lc

Regexper: ^[^@]+@company\.lc

[ ^ ]
