Question

Hi Team

 

I have this following  model, every time i am trying to run my controller its complain about the data type being non-null value be set to System.Int32. How do i solve this issue? this data type is set as float type.

public ActionResult SearchPeopleDetails()
{

    RegCoursesViewModel regCoursesView = new RegCoursesViewModel();
    return View(cb.RegPeopleLists.ToList());  // Exception is here by run time.
}

public class eNtsaRegPeopleLists
{
    public string Name { get; set; }
    [Key]
    public int LoginID { get; set; }
    public string SISID { get; set; }
    public string Role { get; set; }
    public DateTime LastActivity { get; set; }
    public int? TotalActivity { get; set; } // I did this before public float TotalActivity {get;set;}
