Read all the renderings from the context item including page design renderings

Question

I am using Sitecore 10.3 with SXA, I am trying to read all the renderings of the current item and get datasource of a required rendering item based on the item ID, But I am able to see only which are present in final renderings but not able see the renderings from page design.

How can I access the page design renderings.

I tried:

renderingItem.Visualization.GetRenderings(Sitecore.Context.Device, true);

You can use below code snippet to get all the rendering on an item including renderings from page/partial design.

using Sitecore.Data.Fields;
using Sitecore.Data.Items;
using Sitecore.Mvc.Pipelines.Response.GetXmlBasedLayoutDefinition;
using Sitecore.Pipelines;
using System.Web.Mvc;
using System.Xml;
using System.Xml.XPath;

public static class SitecoreHelperExtensions{
  public static void GetRenderings(){
    var args = new GetXmlBasedLayoutDefinitionArgs();
    CorePipeline.Run("mvc.getXmlBasedLayoutDefinition", args);
    var xmlDefinition = args.Result;
    //Get the context device definition
    var deviceNode = xmlDefinition.XPathSelectElement("d[@id='" + (object)Sitecore.Context.Device.ID.ToString() + "']");
    XmlDocument deviceNodeXML = new XmlDocument();
    deviceNodeXML.LoadXml(deviceNode.ToString());
    // Exracts rendering from the context device
    Item contextItem = Sitecore.Context.Item;
    var renderingReferences = 
    LayoutField.ExtractReferences(deviceNodeXML.FirstChild, contextItem.Language, contextItem.Database);
    // code to interate through each renderings
    foreach (var renderingReference in renderingReferences)
    {

    }
  }
}

By calling above snippet SitecoreHelperExtensions.GetRenderings(), you can get all the rendering on an item merged with page/partial design renderings.

Hope this helps!!!
