EnableClientValidation doesn't work

Why doesn't client validation work?

<script src="<%: Url.Content("~/Scripts/jquery-1.4.1.min.js")%>" type="text/javascript"></script>
<script src="<%: Url.Content("~/Scripts/MicrosoftAjax.js")%>" type="text/javascript"></script>
<script src="<%: Url.Content("~/Scripts/MicrosoftMvcValidation.js")%>" type="text/javascript"></script>
<h2>Criar</h2>

<% Html.EnableClientValidation(); %开发者_运维知识库>
<% using (Html.BeginForm())
   { %>
<%: Html.ValidationSummary(false) %>
<%: Html.LabelFor(x => x.Nome) %><%: Html.EditorFor(x => x.Nome) %>
<%: Html.LabelFor(x => x.Email) %><%: Html.EditorFor(x => x.Email) %>
<%: Html.LabelFor(x => x.Senha) %><%: Html.EditorFor(x => x.Senha) %>
<%: Html.LabelFor(x => x.ConfirmacaoSenha) %><%: Html.EditorFor(x => x.ConfirmacaoSenha) %>
<input type="submit" value="Criar Conta" />
<% } %>

This is the model class:

public class CadastroViewModel
    {
        [Required(ErrorMessage = "Por favor digite seu nome")]
        public string Nome { get; set; }
        [Required(ErrorMessage = "Por favor digite seu e-mail")]
        [RegularExpression(".+\\@.+\\..+", ErrorMessage = "Por favor entre com um e-mail válido")]
        public string Email { get; set; }
        [Required(ErrorMessage = "Por favor digite sua senha")]
        public string Senha { get; set; }
        [Required(ErrorMessage = "Por favor confirme sua senha")]
        [DisplayName("Confirmação de Senha")]
        public string ConfirmacaoSenha { get; set; }
    }

You need to add the ValidationMessageFor helper to enable client side validation:

<%: Html.LabelFor(x => x.Nome) %>
<%: Html.EditorFor(x => x.Nome) %>
<%: Html.ValidationMessageFor(x => x.Nome) %>

<%: Html.LabelFor(x => x.Email) %>
<%: Html.EditorFor(x => x.Email) %>
<%: Html.ValidationMessageFor(x => x.Email) %>

<%: Html.LabelFor(x => x.Senha) %>
<%: Html.EditorFor(x => x.Senha) %>
<%: Html.ValidationMessageFor(x => x.Senha) %>

<%: Html.LabelFor(x => x.ConfirmacaoSenha) %>
<%: Html.EditorFor(x => x.ConfirmacaoSenha) %>
<%: Html.ValidationMessageFor(x => x.ConfirmacaoSenha) %>

ValidationSummary does not work with Client Validation. You'll have to add the ValidationMessageFor each element.

e.g.

<%: Html.LabelFor(x => x.Nome) %><%: Html.EditorFor(x => x.Nome) %>  <%: Html.ValidationMessageFor(x => x.Nome)%>
