Umbraco backend customization - handling events

Hook on umbraco events and control them from your code

  • Share

In Umbraco 6 new interface IApplicationHandler is introduced. By inheriting this interface in your class you can hook your custom methods to handle events which occur in Umbraco.

The following two I use really often for controlling Umbraco behavior:

  • MediaService
  • ContentService

Beside these two, you can find others which can help you controlling Umbraco events but I barely use them at anytime. Anyhow, it is good to know that you have them.

Note

This article is related and tested on Umbraco v6.1.6 (Assembly version: 1.0.5021.24867). I am not sure that the same approach can be applied to Umbraco 7

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using Umbraco.Core;
using Umbraco.Core.Services;

namespace Umbraco.Cms.Custom
{
    public class UmbracoEventHandlers : ApplicationEventHandler
    {
        public UmbracoEventHandlers()
        {
            MediaService.Saving += new Core.Events.TypedEventHandler<IMediaService, Core.Events.SaveEventArgs<Core.Models.IMedia>>(MediaService_Saving);
            ContentService.Publishing += new Core.Events.TypedEventHandler<Core.Publishing.IPublishingStrategy, Core.Events.PublishEventArgs<Core.Models.IContent>>(ContentService_Publishing);
            FileService.SavedTemplate += new Core.Events.TypedEventHandler<IFileService, Core.Events.SaveEventArgs<Core.Models.ITemplate>>(FileService_SavedTemplate);
            LocalizationService.SavedLanguage += new Core.Events.TypedEventHandler<ILocalizationService, Core.Events.SaveEventArgs<Core.Models.ILanguage>>(LocalizationService_SavedLanguage);
        }

        void LocalizationService_SavedLanguage(ILocalizationService sender, Core.Events.SaveEventArgs<Core.Models.ILanguage> e)
        {
            throw new NotImplementedException();
        }

        void FileService_SavedTemplate(IFileService sender, Core.Events.SaveEventArgs<Core.Models.ITemplate> e)
        {
            throw new NotImplementedException();
        }

        void ContentService_Publishing(Core.Publishing.IPublishingStrategy sender, Core.Events.PublishEventArgs<Core.Models.IContent> e)
        {
            throw new NotImplementedException();
        }

        void MediaService_Saving(IMediaService sender, Core.Events.SaveEventArgs<Core.Models.IMedia> e)
        {
            throw new NotImplementedException();
        }
    }
}
