XNet.WebUI.Hotel.ViewModel.Rate.RateViewModel vm = new ViewModel.Rate.RateViewModel();
if (search.Request == null)
{
vm.RoomTypeList = ViewModel.DropDown.Builder.RoomTypeBuilder.Build(RoomType, null);
vm.CurrencyList = ViewModel.DropDown.Builder.CurrencyBuilder.Build(currency, null);
}
else
{
vm.RoomTypeList = ViewModel.DropDown.Builder.RoomTypeBuilder.Build(RoomType, search.Request.RoomTypeID);
vm.CurrencyList = ViewModel.DropDown.Builder.CurrencyBuilder.Build(currency, search.Request.Currency);
}
vm.Request = search.Request;
if (search.Request == null)
{
vm.Request = new RateRequest();
vm.Request.CheckInFrom = null;
vm.Request.CheckInTo = null;
vm.Request.RoomTypeID = null;
}
if (search.Request != null)
{
Session["RoomTypeID"] = search.Request.RoomTypeID;
Session["Breakfast"] = search.Request.Breakfast;
Session["Currency"] = search.Request.Currency;
}
vm.listRoomRate = GetDataIndex(vm.Request);
_UserSession.SearchRoomRate = vm;
return RedirectToAction("SearchResult");
}
my New
[HttpPost]
public ActionResult New(ViewModel.Rate.RateViewModel vm)
{
if (vm.NewRoomRate.Currency == null)
vm.NewRoomRate.Currency = "IDR";
var NewData = _RoomRateService.NewRoomRate(vm.NewRoomRate.RoomTypeName, vm.NewRoomRate.Breakfast,
Convert.ToDateTime(vm.NewRoomRate.CheckInFrom), Convert.ToDateTime(vm.NewRoomRate.CheckInTo), vm.NewRoomRate.sun, vm.NewRoomRate.mon, vm.NewRoomRate.tue,
vm.NewRoomRate.wed, vm.NewRoomRate.thu, vm.NewRoomRate.fri, vm.NewRoomRate.sat, vm.NewRoomRate.Currency, vm.NewRoomRate.SingleRate,
vm.NewRoomRate.DoubleRate, vm.NewRoomRate.TripleRate, Convert.ToDecimal(vm.NewRoomRate.Commision), Convert.ToInt32(vm.NewRoomRate.Allotment), vm.NewRoomRate.CloseSelling,
vm.NewRoomRate.FreeSell);
if (NewData == null)
{
ModelState.AddModelError("failed", "RoomRate is already created, please use edit instead");
return New();
}
ViewModel.Rate.RateViewModel test = new ViewModel.Rate.RateViewModel();
test.Request = new RateRequest();
test.Request.RoomTypeID = Convert.ToInt32(vm.NewRoomRate.RoomTypeName);
return RedirectToAction("Index", new {search = test.Request });
}
i try like this, but i get error like this
Server Error in '/' Application.
The model item passed into the dictionary is of type '<>f__AnonymousType0`1[XNet.WebUI.Hotel.ViewModel.RateRequest]', but this dictionary requires a model item of type 'XNet.WebUI.Hotel.ViewModel.Rate.RateViewModel'.
can some one tell me, how i can do this?
thanks

according to the error you are getting:
Server Error in '/' Application.
The model item passed into the dictionary is of type '<>f__AnonymousType0`1[XNet.WebUI.Hotel.ViewModel.RateRequest]', but this dictionary requires a model item of type 'XNet.WebUI.Hotel.ViewModel.Rate.RateViewModel'.
you are specifying that Index will recieve a parameter of type: ViewModel.Rate.RateViewModel named search.
public ActionResult Index(ViewModel.Rate.RateViewModel search)
but you are passing an object of type ViewModel.Rate.RateViewMode in your "NEW" action result.
ViewModel.Rate.RateViewModel test = new ViewModel.Rate.RateViewModel();
test.Request = new RateRequest();
test.Request.RoomTypeID = Convert.ToInt32(vm.NewRoomRate.RoomTypeName);
return RedirectToAction("Index", new {search = test.Request });
to resolve the error you can edit your controller like this:
[HttpPost]
public ActionResult New(ViewModel.Rate.RateViewModel vm)
{
if (vm.NewRoomRate.Currency == null)
vm.NewRoomRate.Currency = "IDR";
var NewData = _RoomRateService.NewRoomRate(vm.NewRoomRate.RoomTypeName, vm.NewRoomRate.Breakfast,
Convert.ToDateTime(vm.NewRoomRate.CheckInFrom), Convert.ToDateTime(vm.NewRoomRate.CheckInTo), vm.NewRoomRate.sun, vm.NewRoomRate.mon, vm.NewRoomRate.tue,
vm.NewRoomRate.wed, vm.NewRoomRate.thu, vm.NewRoomRate.fri, vm.NewRoomRate.sat, vm.NewRoomRate.Currency, vm.NewRoomRate.SingleRate,
vm.NewRoomRate.DoubleRate, vm.NewRoomRate.TripleRate, Convert.ToDecimal(vm.NewRoomRate.Commision), Convert.ToInt32(vm.NewRoomRate.Allotment), vm.NewRoomRate.CloseSelling,
vm.NewRoomRate.FreeSell);
if (NewData == null)
{
ModelState.AddModelError("failed", "RoomRate is already created, please use edit instead");
return New();
}
ViewModel.Rate.RateViewModel test = new ViewModel.Rate.RateViewModel();
return RedirectToAction("Index", new {search = test });
}
hope that helps.
