View called from controller using IHttpHandler returning nothing

I have a custom IHttpHandler that im using to call my controller in MVC3. Problem is that when I call View("~/path/to/my/view.cshtml") I get nothing. No error. Nothing, just empty source and a 200 ok.

Since im calling this my self is there some part of the view life-cycle that's not getting started?


public class MyHttpHandler : IHttpHandler
    ISimpleController _c;

    public SimpleHttpHandler(Controller c)
        _c = c;

    public bool IsReusable
        get { return false; }

    public void ProcessRequest(HttpContext context)

Code from controller:

    public new ActionResult Get()
        ViewBag.Proof = "Ping";
        ViewBag.Of = "Pong";
        ViewBag.Life = "Fizz";
        return View("~/Views/Shared/WhatAView.cshtml");


@foreach(var pair in ViewData)
   <li>@pair.Key : @pair.Value</li>


The only thing you need is to call ExecuteResult() on your ActionResult. This will force rendering of your view. This is what MVC Framework does after it retrieves ActionResult from a controller.


It's important that you implemented controller properly w/ valid ControllerContext. I have decompiled ViewResultBase.ExecuteResult() using dotPeek:

public override void ExecuteResult(ControllerContext context)
  if (context == null)
    throw new ArgumentNullException("context");
  if (string.IsNullOrEmpty(this.ViewName))
    this.ViewName = context.RouteData.GetRequiredString("action");
  ViewEngineResult viewEngineResult = (ViewEngineResult) null;
  if (this.View == null)
    viewEngineResult = this.FindView(context);
    this.View = viewEngineResult.View;
  TextWriter output = context.HttpContext.Response.Output;
  this.View.Render(new ViewContext(context, this.View, this.ViewData, this.TempData, output), output);
  if (viewEngineResult == null)
  viewEngineResult.ViewEngine.ReleaseView(context, this.View);

You see that this method renders the view into ControllerContext.HttpContext. Ensure that HttpContext is avalaible from within your controller.

As seen above you still can use raw rendering:

  TextWriter output = context.HttpContext.Response.Output;
  var viewResult = (ViewResult)_c.Get();
  viewResult.View.Render(new ViewContext(_c.ControllerContext, viewResult.View, viewResult.ViewData, viewResult.TempData, output), output);
