I have the following code;

  [RegularExpression(@"^[\w-\.]+@([\w-]+\.)+[\w-]{2,4}$", ErrorMessage = "Invalid Email Address")]
    public string Email { get; set; }

In my view I have:

<tr><td>Email</td><td><%=Html.TextBox("Email", Html.Encode(Model.Email), new { Class = "edit_control" })%></td><td><%= Html.ValidationMessageFor(model => model.Email)%></td></tr>

My problem is when I insert an invalid email, it still saves. If I let other required fields empty then the message is displayed. Else, if this is the only field with an error, the message doesn`t get displayed.

I want it to display the message and not save the form values.
