如何访问HTML控件在code背后 [英] How to access html controls in code behind

问题描述

我想按照这个<一个href=\"http://www.asp.net/web-forms/tutorials/security/membership/validating-user-credentials-against-the-membership-user-store-cs\">example如何验证凭据。然而，它使用的asp：控制登录表单

I'm trying to follow this example on how to validate credentials. However, it uses asp: controls for the login form.

如果我是用HTML控件代替CSS样式可以应用，如：

If I were to use html controls instead so CSS styles can be applied, eg

<div id="login">
<a href="#" id="lclose"></a>

        <form action="#" runat="server">
            <fieldset>
                <div class="frame">
                    <h4>Login</h4>
                    <small>Sign in to your account.</small>
                    <div class="clear"></div>
                    <input type="text" value="Username" class="input-text autoclear" />
                    <input type="password" value="Password" class="input-text autoclear"/>
                </div>

                <div class="separator"></div>

                <div>
                <input type="submit" value="Sign in" class="input-submit float-right" runat="server" onserverclick="LoginButton_Click"/>
                <a href="#" class="float-left">Forgot your password?</a>
                </div>

            </fieldset>
        </form>

</div>

我如何访问用户名和放大器;密码背后类似code？

How do I access the Username & Password in code behind similar to?

protected void LoginButton_Click(object sender, EventArgs e)
{
    // Validate the user against the Membership framework user store
    if (Membership.ValidateUser(UserName.Text, Password.Text))
    {
        // Log the user into the site
        FormsAuthentication.RedirectFromLoginPage(UserName.Text, RememberMe.Checked);
    }
    // If we reach here, the user's credentials were invalid
    InvalidCredentialsMessage.Visible = true;
}

什么是正确的语法，而不是 UserName.Text，Password.Text ？

推荐答案

添加 ID 和 RUNAT 服务器属性输入的标记（见下文）

Add id and runat server attributes to the input tag (see below)

<input type="text" value="Username" class="input-text autoclear"  id="Username" runat="server"/>
<input type="password" value="Password" class="input-text autoclear" id="Password" runat="server"/>

您还需要修改文本到值在code：

You also need to change Text to Value in your code:

protected void LoginButton_Click(object sender, EventArgs e)
{
    // Validate the user against the Membership framework user store
    if (Membership.ValidateUser(Username.Value, Password.Value))
    {
        // Log the user into the site
        FormsAuthentication.RedirectFromLoginPage(UserName.Value, RememberMe.Checked);
    }
    // If we reach here, the user's credentials were invalid
    InvalidCredentialsMessage.Visible = true;
}

您还可以添加一个HTML 复选框为与rememberMe

You can also add a html checkbox for RememberMe

<input id="RememberMe" type="checkbox" runat="server" value ="RememberMe"/>

现在可以通过调用检查检查状态 RememberMe.Checked

Now you can check the checked states by calling RememberMe.Checked
