in your action method that you post data to ,did you check if the model is valid ?

[HttpPost]
public ActionResult MyActionMethod(Model model)
{
  if(!ModelState.IsValid)
  {
     return View(model);
  }
  //else post data
}

if you want to display error message for the Integer you can try

[Required(ErrorMessage="Age Is Required")]
[Integer(ErrorMessage="Numbers Only")]
public int Age { get; set; }

if there is still a prob please post your view , model and controller code

i even not able to decorete my int property with [Integer]

ensure you imported the proper namespace [Integer] public int Age { get; set; } works

on the top of your file put using DataAnnotationsExtensions;

if you put that line and there is a compile problem use nuget again and add reference because the dll is not referenced by that project
