ASP.NET MVC – Returning a PartialView to Ajax along with another object

So – using the following posts I got this working:

Partial Views vs. Json (or both)

Render a view as a string

They both lay it out nicely, then I changed my code to the following:

C#:

public ActionResult GetSomePartialView(SomeArgumentModel someArguments)
{
    ReturnArgs r = new ReturnArgs();

    bool isAllowed = CheckPermissions(); 

    if (isAllowed) 
    {
        r.Status = 400; //good status ... proceed normally
        r.ViewString = this.RenderViewToString("_CaseManager");
    }
    else
    {
        r.Status = 300; //not good ... display permissions pop up
        r.ViewString = this.RenderViewToString("_DefaultView");
    }

    return Json(r);
}

public class ReturnArgs
{
    public ReturnArgs()
    {
    }

    public int Status { get; set; }
    public string ViewString { get; set; }
}

JS:

$.ajax({
    type: "GET",
    url: "/Home/GetSomePartialView/",
    data: someArguments,
    success: function (jsReturnArgs) { 

        if (jsReturnArgs.Status === 300) { //300 is an arbitrary value I just made up right now
            showPopup("You do not have access to that.");
        }

        $("#someDiv").html(jsReturnArgs.ViewString); //the HTML I returned from the controller
    },
    error: function (errorData) { onError(errorData); }
});
