TempData is populated in the Base method, but turns to null as soon as the code returns back to the derived controller's method.
Derived Controller Edit Action (Post):
public class ManageItemsController : BaseController
{
private BaseControllerSingle<Item, ItemViewModel> GetBaseControllerSingle()
{
return new BaseControllerSingle<Item, ItemViewModel>(_itemRepository, AreaName, ControllerName);
}
...
// POST: /InventoryMgmt/ManageItems/Edit/5
[HttpPost]
public ActionResult Edit(ItemViewModel ItemViewModel)
{
ItemViewModel = _manageItemsAppServ.SaveOrUpdate(ItemViewModel, CurrentCompanyId);
return GetBaseControllerSingle().EditPost(
ItemViewModel,
x => x.Id == ItemViewModel.Item.Id && x.CompanyId == CurrentCompanyId
);
}
Base Controller Edit Action:
public class BaseControllerSingle<TRepository, TViewModelSingle> : BaseController
where TRepository : class, IEntity, IAuditStamps, new()
where TViewModelSingle : class, IEntity, IViewModelSingle<TRepository, TViewModelSingle>, new()
{
...
public virtual ActionResult EditPost(
TViewModelSingle viewModel,
Expression<Func<TRepository, bool>> predicate = null
)
{
if (ModelState.IsValid)
{
BaseAppServSingle<TRepository, TViewModelSingle> baseAppServSingle =
new BaseAppServSingle<TRepository, TViewModelSingle>(_repository);
ActionConfirmation<int> result = baseAppServSingle.SaveOrUpdate(
viewModel,
CurrentUserId,
predicate
);
TempData["message"] = result.Message;
if (result.WasSuccessful)
{
return RedirectToAction("Edit", new { id = result.Value });
}
}
TempData["message"] = "There is invalid data on the form.";
return View(viewModel);
}
