Question

I am using DataAnnotations for form field validation. So for example I have a contact model with the below property:

   [Required(ErrorMessage = "Please enter your first name.")]  
   [StringLength(100)]
   public string   FirstName      { get; set; }

But instead of the error appearing at the side of each control, I need them to appear in a list above the form itself. What is the best way to do that?

Thanks.

See:

 @Html.ValidationSummary(true)  // to not show property error
 @Html.ValidationSummary(false)  // to include property errors

Put that on top or whereever in your form and it’ll summarize all your validation errors.
