RenderLayout pipeline implementation in sitecore with C# code with example

The RenderLayout pipeline in Sitecore is used to process the layout of a page and generate the final HTML output. It is a series of processors that perform specific tasks, such as setting up the rendering context, executing the layout definition, and rendering the sublayouts.

Here is an example of how to implement the RenderLayout pipeline in Sitecore with C# code:

using Sitecore.Pipelines;

using Sitecore.Mvc.Pipelines.Response.RenderRendering;

using Sitecore.Mvc.Presentation;

using System.Web.Mvc;

namespace MyProject.Pipelines.RenderLayout

{

    public class CustomRenderLayout : RenderLayoutProcessor

    {

        public override void Process(RenderLayoutArgs args)

        {

            // Get the current rendering context

            var renderingContext = RenderingContext.CurrentOrNull;

            if (renderingContext == null)

            {

                return;

            }

            // Get the current rendering

            var rendering = renderingContext.Rendering;

            if (rendering == null)

            {

                return;

            }

            // Get the layout definition

            var layoutDefinition = rendering.LayoutDefinition;

            if (string.IsNullOrEmpty(layoutDefinition))

            {

                return;

            }

            // Get the controller rendering

            var controllerRendering = rendering as ControllerRendering;

            if (controllerRendering == null)

            {

                return;

            }

            // Get the controller action

            var controller = controllerRendering.Controller;

            if (controller == null)

            {

                return;

            }

            // Perform custom logic here

            // Call the base implementation

            base.Process(args);

        }

    }

}

This pipeline implementation can be registered in the Sitecore configuration file, typically located at /App_Config/Include/MyProject/MyProject.RenderLayout.config:

<configuration xmlns:patch="http://www.sitecore.net/xmlconfig/">

  <sitecore>

    <pipelines>

      <renderLayout>

        <processor type="MyProject.Pipelines.RenderLayout.CustomRenderLayout, MyProject" patch:before="processor[@type='Sitecore.Mvc.Pipelines.Response.RenderLayout.RenderLayout, Sitecore.Mvc']" />

      </renderLayout>

    </pipelines>

  </sitecore>

</configuration>

In this example, the custom pipeline implementation CustomRenderLayout is registered to run before the default Sitecore.Mvc.Pipelines.Response.RenderLayout.RenderLayout processor.
