Manually invoking ModelState validation

Question

I\'m using ASP.NET MVC 3 code-first and I have added validation data annotations to my models. Here\'s an example model:

public class Product
{
    public i         


        

Answer 1

            //
            var context = new ValidationContext(model);

            //If you want to remove some items before validating
            //if (context.Items != null && context.Items.Any())
            //{
            //    context.Items.Remove(context.Items.Where(x => x.Key.ToString() == "Longitude").FirstOrDefault());
            //    context.Items.Remove(context.Items.Where(x => x.Key.ToString() == "Latitude").FirstOrDefault());
            //}

            List validationResults = new List();
            bool isValid = Validator.TryValidateObject(model, context, validationResults, true);
            if (!isValid)
            {
                //List of errors 
                //validationResults.Select(r => r.ErrorMessage)
                //return or do something
            }
