jquery検証を使用してこれを行う方法です。あなたのブートストラップで試してみてください。私はそれをテストしたので、この作品が分かります。ここでは、コントローラは次のとおりです。ここで
public class NamesAndLocation
{
public string FirstName { get; set; }
public string LastName { get; set; }
public string Location { get; set; }
}
public class NamesAndLocationList
{
public IList<NamesAndLocation> NamesAndLocation { get; set; }
}
public class HomeController : Controller
{
public ActionResult Index10() //this Method name can change
{
NamesAndLocationList list = new NamesAndLocationList();
list.NamesAndLocation = new List<NamesAndLocation>();
list.NamesAndLocation.Add(new NamesAndLocation { FirstName = "fn1", LastName = "ln1", Location = "loc1" });
list.NamesAndLocation.Add(new NamesAndLocation { FirstName = "fn2", LastName = "ln2", Location = "loc2" });
list.NamesAndLocation.Add(new NamesAndLocation { FirstName = "fn3", LastName = "ln3", Location = "loc3" });
return View(list);
}
が図である。

ボックス検証属性のうちで、私は良いを見つけたことはありませんソリューションであり、多くの場合、https://github.com/JeremySkinner/FluentValidationまたはhttps://foolproof.codeplex.com/ –
に依存しています。独自の検証属性を記述します - [ASP.NET MVC 3での検証の完全ガイド - 第2部] （ht tp：//www.devtrends.co.uk/blog/the-complete-guide-to-validation-in-asp.net-mvc-3-part-2） –
