Alternative for ViewBag in MVC3
I have a MVC3 web application where I need to implement a database search functionality. I am creating a ViewModel class for my search form so that I get the search parameters from View to controller. I can successfully get all my search parameters (which includes search query and check boxes if user wants to narrow search) in m开发者_如何转开发y controller class and retrieve data from database using repository pattern
var searchResult = _repository.GetItems(searchParms, chkbox1, chkbox2, ..., chkbox10)
After this, I am passing my searchResult to pagination helper like
var paginatedSearchResult = new PaginatedList<Items>(searchResult, page ?? 0, pageSize);
I am displaying the retrieved data in my view page
return View(paginatedSearchResult)
The problem, I am facing is, besides the data from the database, I also need to show the search query string and topic (for which checkbox was used) in my view page so that user can see what they searched for. I did not find any proper solution to this and had to use ViewBag. And now my Controller page looks ugly with more than 10 ViewBag. I know there must some good solution to this but I am not able to find it.Any suggestions will be highly appreciated.
Thanks, ACS
Direct answer to question's title is - alternative for viewbag in mvc is strongly typed ViewModel classes. Take a look at Create View Models
You are soooo close already. You have a ViewModel you are using for the search - so you obviously know how to create a view model. Just create a new ViewModel that has your current ViewModel as a property and the database search viewmodel as a property.
public class SearchViewModel { public YourExistingSearchOptionsViewModel SearchViewModel {get;set} public PaginatedList SearchResults {get;set;} }
obviously that is very rough - but hopefully you get the idea there.
I think you might be searching for the strongly typed "ViewData" property
