C# RequiredFieldValidator在我的ASp站点中不工作

在VisualStudio中创建预订页面时，我正在尝试学习一些C#&asp。我在RequiredFieldValidator方面遇到了一个小问题，因为当我单击按钮时，什么也没有发生

我正在使用引导css文件使其更加闪亮此处是注册页面的一些代码：

更新代码

<asp:Content ID="RegistrationContent" ContentPlaceHolderID="MainContent" runat="server">

<br />
<div class="container">
    <h2>Registration</h2>
    <p>Please fill out the forms to complete your registration.</p>
    <form role="form">
        <div class="form-group">
            <label for="username">Name:</label>
            <asp:TextBox runat="server" ID="UserName" CssClass="form-control" />
            <asp:RequiredFieldValidator runat="server" ControlToValidate="UserName"
                CssClass="text-danger" ErrorMessage="The user name field is required." ID="RequiredFieldValidator1" ValidationGroup="Registration" />
        </div>
        <div class="form-group">
            <label for="email">Email:</label>
            <asp:TextBox runat="server" ID="Email" CssClass="form-control" />
            <asp:RequiredFieldValidator runat="server" ControlToValidate="Email"
                CssClass="text-danger" ErrorMessage="The email field is required." ID="RequiredFieldValidator2" ValidationGroup="Registration" />
        </div>
        <div class="form-group">
            <label for="password">Password:</label>
            <asp:TextBox runat="server" ID="Password" CssClass="form-control" TextMode="Password" />
            <asp:RequiredFieldValidator runat="server" ControlToValidate="Password"
                CssClass="text-danger" ErrorMessage="An password is required." ID="RequiredFieldValidator3" ValidationGroup="Registration" />
        </div>
        <div class="form-group">
            <label for="confirmpassword">Confirm Password:</label>
            <asp:TextBox runat="server" ID="ConfirmPassword" CssClass="form-control" ValidationGroup="Registration" TextMode="Password" />
            <asp:RequiredFieldValidator runat="server" ControlToValidate="ConfirmPassword"
                CssClass="text-danger" ErrorMessage="An password is required." ID="RequiredFieldValidator4" ValidationGroup="Registration" />
        </div>
        <div class="form-group">
            <button type="button" ValidationGroup="Registration" class="btn btn-primary btn-sm">Create</button>
            &nbsp;
            <button type="reset" ValidationGroup="Registration" class="btn btn-primary btn-sm">Reset</button>
        </div>
    </form>
</div>

已创建validationgroup，但它仍然不起作用。。还有其他建议吗？

您只是错过了一件小事，即为按钮和所需的字段验证器分配一个验证组。您的代码应该是：

<div class="container">
    <h2>Registration</h2>
    <p>Please fill out the forms to complete your registration.</p>
    <form role="form">
        <div class="form-group">
            <label for="username">Name:</label>
            <asp:TextBox runat="server" ID="UserName" CssClass="form-control" />
            <asp:RequiredFieldValidator ID="RequiredFieldValidator1" runat="server" ControlToValidate="UserName"
                CssClass="text-danger" ErrorMessage="The user name field is required." ValidationGroup="Group1" />
        </div>
        <div class="form-group">
            <label for="email">Email:</label>
            <asp:TextBox runat="server" ID="Email" CssClass="form-control" />
            <asp:RequiredFieldValidator ID="RequiredFieldValidator2" runat="server" ControlToValidate="Email"
                CssClass="text-danger" ErrorMessage="The email field is required." ValidationGroup="Group1" />
        </div>
        <div class="form-group">
            <label for="password">Password:</label>
            <asp:TextBox runat="server" ID="Password" CssClass="form-control" />
            <asp:RequiredFieldValidator ID="RequiredFieldValidator3" runat="server" ControlToValidate="Password"
                CssClass="text-danger" ErrorMessage="An password is required." ValidationGroup="Group1" />
        </div>
        <div class="form-group">
            <label for="confirmpassword">Confirm Password:</label>
             <asp:TextBox runat="server" ID="ConfirmPassword" CssClass="form-control" />
            <asp:RequiredFieldValidator ID="RequiredFieldValidator4" runat="server" ControlToValidate="ConfirmPassword"
                CssClass="text-danger" ErrorMessage="An password is required." ValidationGroup="Group1" />
        </div>
        <div class="form-group">
            <asp:button ValidationGroup="Group1" type="button" class="btn btn-primary btn-sm">Create</asp:button>
            &nbsp;
            <asp:button ValidationGroup="Group1" type="reset" class="btn btn-primary btn-sm">Reset</asp:button>
        </div>
    </form>

仍然不起作用。。我不确定我做错了什么。。没有之前的，当我遵循没有引导css的教程时，它工作了。发现了问题。。你的代码是对的。。是按钮引起了问题。
