An example:
Controller:
[AcceptVerbs(HttpVerbs.Post)]
public ActionResult Index(Company company)
{
//validate and save data
if (ValidateCompanyData(company))
{
_service.SaveCompanyData(CustomerId, company);
ViewData["info"] = "Your changes have been saved.";
}
var companyViewData = GenerateCompanyViewData(company);
return View("Index", companyViewData);
}
[NonAction]
public bool ValidateCompanyData(Company company)
{
if (!company.VAT.HasValue())
{
ModelState.AddModelError("VAT", "'Vat' is a required field.");
}
if (!company.CompanyName.HasValue())
{
ModelState.AddModelError("CompanyName", "'Name' is a required field.");
}
return ModelState.IsValid;
}
View:
Html.ValidationMessage("VAT")
To access the errormessage.
In case you're wondering: .HasValue() is an extension method that is the same as !string.IsNullorEmpty()
