how to return multiple selected values in a controller in ASP.NET MVC

Question

I have a controller which I want it to return only two selected rows to a view. It looks like this:

public ActionResult Details(int sourceId, int targetId)
    {
        ConfigurationItem sourceItem = db.ConfigurationItemSet.Find(sourceId);
        ConfigurationItem targetItem = db.ConfigurationItemSet.Find(targetId);

        return View();
    }

What should I put in a "return"? I want to make a view with only two specific rows selected by Id from the table and put it in two separate grids.

If you are not using any Model then try using ViewBag

You should use a ViewModel (thats the recommended way in MVC).

The ViewModel

public class DetailsViewModel
{
    public ConfigurationItem TargetItem { get; set; }
    public ConfigurationItem SourceItem { get; set; }
}

The Action Method

public ActionResult Details(int sourceId, int targetId)
{
    var viewModel = new DetailsViewModel();
    viewModel.TargetItem  = db.ConfigurationItemSet.Find(targetId);
    viewModel.SourceItem = db.ConfigurationItemSet.Find(sourceId);
    return View(viewModel);
}

The View (Razor)

@model DetailsViewModel

// use Model.TargetItem  and Model.SourceItem

you can do it like

Action

public ActionResult Details(int sourceId, int targetId)
{
    var sourceItem  = new list<ConfigurationItem>(); 

    ConfigurationItem sourceItem1 = db.ConfigurationItemSet.Find(sourceId);
    ConfigurationItem targetItem2 = db.ConfigurationItemSet.Find(targetId);
    sourceItem.add(sourceItem1);
    sourceItem.add(sourceItem2);
    return View(sourceItem.AsEnumerable());
}

View

@model IEnumerable<ConfigurationItem>

If you are not using any Model then try using ViewBag.sourceItem to pass data from Controller to your View

ViewBag.sourceItem = db.ConfigurationItemSet.Find(sourceId);
ViewBag.targetItem = db.ConfigurationItemSet.Find(targetId);

This is correct. But it is not the "right" way to use a viewbag. I find them really unorganized and hard to keep track on. I would use a model with it.
