ASP.NET MVC - How to use Required message inside a EditorTemplates

asp.net-mvc, asp.net-mvc-4, mvc-editor-templates, razor

Solution

This works:

 @{
     string requiredMsg = "";
     foreach (var attr in @Html.GetUnobtrusiveValidationAttributes(@ViewData.TemplateInfo.HtmlFieldPrefix, @ViewData.ModelMetadata))
     {
         if (attr.Key == "data-val-required") {
             requiredMsg = attr.Value.ToString();
         }
     }
 }

or this:

 @{
     string requiredMsg = "";
     IEnumerable<ModelClientValidationRule> clientRules = ModelValidatorProviders.Providers.GetValidators(ViewData.ModelMetadata, ViewContext).SelectMany(v => v.GetClientValidationRules());
     foreach (ModelClientValidationRule rule in clientRules)
     {
         if (rule.ValidationType == "required")
         {
             requiredMsg = rule.ErrorMessage;
         }
     }
 }

Problem

I have a simple model: ``` public abstract class Person { [Required(ErrorMessage = "Il nome è obbligatorio!!!")] [UIHint("txtGeneric")] [Display(Name = "Nome")] public string Name { get; set; } [Required(ErrorMessage = "Il cognome è obbligatorio!!!")] [UIHint("txtGeneric")] [Display(Name = "Cognome")] public string Surname { get; set; } [Required(ErrorMessage = "L'email è obbligatoria e deve essere in formato valido (nome@dominio.it)!!!")] [UIHint("txtEmail")] [Display(Name = "E-mail")] public string Email { get; set; } } ``` I created inside the EditorTemplate the txtGeneric.cshtml file. It is like this: ``` @model string <input name="@ViewData.TemplateInfo.HtmlFieldPrefix" id="@ViewData.TemplateInfo.HtmlFieldPrefix" data-validation="required" data-validation-error-msg="MESSAGE_TO_PUT" value="@Model" /> ``` I want to know how to take the text associated Errormessage of Required attribute to put into my txtGeneric.cshtml file. How can I do that? Thanks
