<% Html.EnableClientValidation(); %>
<% 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) %>
