The following example shows how to replace a component for the entire system. This example also shows how to replace the built-in Episerver CMS page tree with a custom page list component.

  1. Declare a replacement component.
    C#
    // A simple component implementation represented with a dijit content pane on the client side
    public class MyCustomPageList : ComponentBase
    {
        public MyCustomPageList() : base("dijit/layout/ContentPane") 
        {
            // Add "Hello World!" as non-persisted content to the dijit content pane
            this.Settings.Add(new Setting("content", "Hello World!", false));
        }
    }
    
  2. Replace the page tree component using the IOC container by implementing the ConfigureContainer method of EPiServer.ServiceLocation.IConfigurableModule in an initialization module.
    C#
    public void ConfigureContainer(ServiceConfigurationContext context)
    {
        context.Container.Configure(container =>
        {
            container.For<IComponent>().Add<MyCustomPageList>()
                .Named(new PageTreeComponent().DefinitionName);
        });
    }
    

    This replaces any creation of the PageTreeComponent with a new instance of the MyCustomPageList type that is created by the IOC container.
