public WorkOnTicketCreateModel WorkOnTicketCreateModel { get; set; }
}
public class TicketModelBase
{
[Required]
[Range(1, int.MaxValue, ErrorMessage = "Please enter a value bigger than {0}")]
public int EstimatedTime { get; set; }
public virtual List<WorkOnTicket> WorkOnTickets { get; set; }
}
public class WorkOnTicketCreateModel : WorkOnTicketModelBase
{
[Required]
[Display(Name = "AssignedToUser")]
public int AssignedToUserId { get; set; }
public IEnumerable<SelectListItem> AssignedUser { get; set; }
[Required]
[Display(Name = "Ticket Status")]
public int TicketStatusId { get; set; }
public TicketStatus TicketStatusVal { get; set; }
public IEnumerable<SelectListItem> TicketStatus { get; set; }
}
public class WorkOnTicketModelBase
{
public int Id { get; set; }
[Required]
public int EstimateHours { get; set; }
[Required]
[Range(1, int.MaxValue, ErrorMessage = "Please enter a value bigger than {0}")]
public int WorkedHours { get; set; }
}
Contoller:
[HttpPost]
[AcceptVerbs(HttpVerbs.Post)]
public ActionResult Details(TicketDetailModel model, IEnumerable<HttpPostedFileBase> file)
{
using (ITransaction transaction = this.nhSession.BeginTransaction())
{
var ticketObj = this.nhSession.QueryOver<Ticket>().Where(t => t.Id == model.Id).SingleOrDefault();
var workOnTicket = new WorkOnTicket();
workOnTicket.Ticket = ticketObj;
workOnTicket.WorkedHours = model.WorkOnTicketCreateModel.WorkedHours;
workOnTicket.EstimateHours = model.WorkOnTicketCreateModel.EstimateHours;
ticketObj.WorkOnTickets.Add(workOnTicket);
this.nhSession.Save(ticketObj);
transaction.Commit();
}
return RedirectToAction("Details", new { id = model.Id, milestoneId = model.Milestone.Id, projectId = model.Project.Id });
}
View:-
#model AnkTech.TicketManagement.Web.Models.Ticket.TicketDetailModel
#using (Html.BeginForm("Details", "Ticket", FormMethod.Post, new { enctype = "multipart/form-data" }))
{
#Html.ValidationSummary(true)
#Html.TextBoxFor(model => model.WorkOnTicketCreateModel.EstimateHours, new { #id = "work_remaining", #class = "s-mini", size = "2" })
Worked hours: #Html.TextBoxFor(model => model.WorkOnTicketCreateModel.WorkedHours, new { #id = "worked_hours", #class = "s-mini", size = "2" })
<input type="submit" value="Submit" tabindex="2" name="commit" id="submit-comment"
class="gray-btn">
}
I have deleted all rmaining fields. i have added only fields to which related i am asking, please help.

You need to use ModelState.IsValid to check that the model is actually valid. Currently you assign validation attributes but never check them:
[HttpPost]
[AcceptVerbs(HttpVerbs.Post)]
public ActionResult Details(TicketDetailModel model, IEnumerable file) {
if (!ModelState.IsValid)
{
// Handle error
}
else
{
using (ITransaction transaction = this.nhSession.BeginTransaction()) {
var ticketObj = this.nhSession.QueryOver<Ticket>().Where(t => t.Id == model.Id).SingleOrDefault();
var workOnTicket = new WorkOnTicket();
workOnTicket.Ticket = ticketObj;
workOnTicket.WorkedHours = model.WorkOnTicketCreateModel.WorkedHours;
workOnTicket.EstimateHours = model.WorkOnTicketCreateModel.EstimateHours;
ticketObj.WorkOnTickets.Add(workOnTicket);
this.nhSession.Save(ticketObj);
transaction.Commit();
}
}
return RedirectToAction("Details", new { id = model.Id, milestoneId = model.Milestone.Id, projectId = model.Project.Id });
}
