Question

I have an issue with a particular controller action not displaying the view.

Here is the Controller Action:

public ActionResult DisplayStudents(string id)
        {
            var name = (from p in data.StudentTable.Where(a => a.ClassNumberID == id)
                                  group n by n.StudentName into g
                                  select g.Key).First();

            return View(name);
        }

Controller Name is “Student” and the view is present in “Views/Student/DisplayStudents.aspx”

Why do I still get this error:

Server Error in '/' Application.
--------------------------------------------------------------------------------

The view 'Thomas Guenn' or its master was not found. The following locations were searched:
~/Views/Student/Thomas Guenn.aspx
~/Views/Student/Thomas Guenn.ascx
~/Views/Shared/Thomas Guenn.aspx
~/Views/Shared/Thomas Guenn.ascx 

Also, why is it looking for “Thomas Guenn.aspx” instead of “DisplayStudents.aspx” ?

Here is my View page:

>” %>

DisplayStudents

Students are listed below:

<table>

<% foreach (var item in Model) { %>
     <tr>
        <td>
            <%= Html.Encode(item)%>
        </td>
    </tr>

<% } %>

</table> </body> </html>

Answer 1

Because your View(name); call is calling overload View(string viewName). If you want to pass string as Model then try using

return View((object)name);

instead.

If this doesn’t work, try to specify viewName explicitly, using overload View(string viewName, object model) like this:

return View("DisplayStudents", name);

UPD: Looking at your view code, I can say that it won’t return expected page either: you’re returning a single string item as a model from controller, but your DisplayStudents.aspx expects a collection. You should also either correct your view (so it will accept single string as model) or return an IEnumerable<string> from controller – by removing .First() from LINQ expression for name.
