This topic describes how to replace a component from the entire system, in the Episerver user interface.

Example

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.

   // 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.

   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.
