how to check the contents of a viewbag in razor

Question

Is there any way to check viewbag content, what the viewbag has of data in the view. my controller send possibly new data each time i click on button and send it with the same named viewbag.

here my controller

public ActionResult Details(string IncomRequest, Int Id)
  {
// some code......
    switch (IncomRequest)
    {

        case ("Order"):
            ViewBag.Query = list<Ordr> Ord;
           break;

        case ("Process"):
            ViewBag.Query = lis<Process> pro;
            break;
   }
  return view();

in my view i want to check what the viewbag contains is it Ord or pro.

Answer 1

In your view you can do something like this:

// if this is true then there's nothing there
@if (ViewBag.Query == null)

further you can do this:

// it was set by the "Order" case
@if (ViewBag.Query is List<Ordr>)

Answer 2

Yes you can

@if(ViewBag.Query is List<Ordr>)
{
    // List<Ordr>
}
else if(ViewBag.Query is List<Process>)
{
    // List<Process>
}
