Cannot change mvc layout in SiteCore 8.0 (update 3) from code

I am trying to change layout in SiteCore 8.0 (update 3) for all my pages from code behind.
I am using layout resolver pipeline for it.
i can debug & see changed path, but cannot get updated layout on UI. I have seen various post by googling, who are doing same thing but those are quite old (older then 2-3 yrs).

below is my layout resolver pipeline code

public class LayoutResolver : HttpRequestProcessor
public LayoutResolver()
System.Diagnostics.Trace.WriteLine("PipeLine: ctor() has been called");
/// <summary>
/// Gets the layout for the page
/// </summary>
/// <param name="args"></param>
public override void Process(HttpRequestArgs args)
System.Diagnostics.Trace.WriteLine("PipeLine: This is atleast called");
Assert.ArgumentNotNull(args, "args");
if (!CanProcess())
Context.Page.FilePath = "/Views/Shared/BusinessLayout_Two.cshtml";

private static bool CanProcess()
return Context.Database != null
&& !IsCore(Context.Database);
private static bool IsCore(Database database)
return database.Name == Constants.CoreDatabaseName;

EDIT : showconfig.config show my resolver register in config.
SiteCoreSample.Helpers.LayoutResolver is my resolver.

<processor type="Sitecore.Pipelines.HttpRequest.LayoutResolver, Sitecore.Kernel"/>
<processor type="SiteCoreSample.Helpers.LayoutResolver, SiteCoreSample" patch:source="Sitecore.Mvc.config"/>
<processor type="Sitecore.Mvc.Pipelines.HttpRequest.TransferMvcLayout, Sitecore.Mvc" patch:source="Sitecore.Mvc.config"/>
<processor type="Sitecore.Mvc.Pipelines.HttpRequest.TransferControllerRequest, Sitecore.Mvc" patch:source="Sitecore.Mvc.config"/>
<processor type="Sitecore.ExperienceEditor.Pipelines.HttpRequest.CheckDevice, Sitecore.ExperienceEditor" patch:source="Sitecore.ExperienceEditor.config"/>
<processor type="Sitecore.Pipelines.HttpRequest.PageEditorHandleNoLayout, Sitecore.ExperienceEditor" patch:source="Sitecore.ExperienceEditor.config"/>
<processor type="Sitecore.ExperienceExplorer.Business.Pipelines.HttpRequest.ExecuteRequest, Sitecore.ExperienceExplorer.Business" patch:source="Sitecore.ExperienceExplorer.config"/>

Since you are using MVC you need to add procesors to a different set of pipelines, the LayoutResolver pipeline you mention is only relevant for Webforms projects..

I would suggest you create another Layout item under /sitecore/layout/Layouts for your secondary MVC layout. Then create processor that will switch the layout item to the secondary one as required:

using System;
using Sitecore;
using Sitecore.Mvc.Pipelines.Response.GetPageRendering;

namespace MyProject.CMS.Custom.Pipelines.GetPageRendering 
    public class GetCustomLayoutRendering : GetPageRenderingProcessor
        public override void Process(GetPageRenderingArgs args)
            if (args.Result == null)

            if (!ShouldSwitchLayout()) //or whatever your custom logic is

            args.Result.LayoutId = new Guid("{guid-to-alt-layout}");
            args.Result.Renderer = null;

And the patch the processor in to the mvc.getPageRendering pipeline:

  <processor type="MyProject.CMS.Custom.Pipelines.GetPageRendering.GetCustomLayoutRendering, MyProject.CMS.Custom"/>

It's important to set args.Result.Renderer to null, since that will force the rendering to be refetched and use the alternative layout from the ID you just set.
