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 my 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

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.

Direct answer to question's title is - alternative for viewbag in mvc is strongly typed ViewModel classes. Take a look at Create View Models

I think you might be searching for the strongly typed "ViewData" property
