Merge validation summary in single line(All required validation in single line,All invalid field validation in single line etc) - asp.net-mvc

Question

I am creating one ASP.NET MVC Application using JQuery,KnockOutJs etc.
I have one model for SignUp and use client side validation only.
public class SignUp
{
[Required(ErrorMessageResourceType = typeof(Messages), ErrorMessageResourceName = MessagesConst.UserNameIsRequired, AllowEmptyStrings = false)]
[StringLength(30, ErrorMessageResourceName = MessagesConst.UserNameLength, ErrorMessageResourceType = typeof(Messages))]
[RegularExpression(#"^[a-zA-Z ]*$", ErrorMessageResourceType = typeof(Messages), ErrorMessageResourceName = MessagesConst.OnlyAlphabetsAndSpaceAreAllowed)]
public string UserName { get; set; }
[RegularExpression(#"^\s*[_A-Za-z0-9-]+(\.[_A-Za-z0-9-]+)*#[A-Za-z0-9-]+(\.[A-Za-z0-9-]+)*(\.[A-Za-z]{2,4})[ ]*$", ErrorMessageResourceType = typeof(Messages), ErrorMessageResourceName = MessagesConst.InvalidEmail)]
[Required(ErrorMessageResourceType = typeof(Messages), ErrorMessageResourceName = MessagesConst.EmailIsRequired, AllowEmptyStrings = false)]
[StringLength(256, ErrorMessageResourceName = MessagesConst.EmailLength, ErrorMessageResourceType = typeof(Messages))]
public string Email { get; set; }
[DataType(DataType.Password)]
[StringLength(50, ErrorMessageResourceName = MessagesConst.PasswordRange, ErrorMessageResourceType = typeof(Messages),MinimumLength = 6)]
[Required(ErrorMessageResourceType = typeof(Messages), ErrorMessageResourceName = MessagesConst.PasswordRequired, AllowEmptyStrings = false)]
public string Password { get; set; }
[DataType(DataType.Password)]
[Compare("Password", ErrorMessageResourceName = MessagesConst.InvalidConfirmPassword, ErrorMessageResourceType = typeof(Messages))]
public string ConfirmPassword { get; set; }
public bool IsNewsLetter { get; set; }
public bool RememberMe { get; set; }
}
I m showing validation summary on view.

Answer 1

You could try #Html.ValidationSummary().ToString().Replace("\r\n", "").Replace("\n", "").Replace("\r", "")
I'm not sure how validationsummary spits out its linebreaks, however, so you can probably find out and cut that down.
