Latch on to the ContentService.Saving event more details can be seen here:

https://our.umbraco.org/documentation/reference/events/contentservice-events

Check out the subsection titled 'What happened to Creating and Created events?'

This documentation suggest this should work however it only fires when you save the document for the first time! Maybe someone else in the community knows a solution.

public class ApplicationEventHandler : IApplicationEventHandler
        {
            public void OnApplicationStarting(UmbracoApplicationBase umbracoApplication, ApplicationContext applicationContext)
            {

            }

            public void OnApplicationInitialized(UmbracoApplicationBase umbracoApplication, ApplicationContext applicationContext)
            {


            }

            public void OnApplicationStarted(UmbracoApplicationBase umbracoApplication, ApplicationContext applicationContext)
            {
                ContentService.Saving += DocumentTypeName;
            }

            private void DocumentTypeName(IContentService sender, Umbraco.Core.Events.SaveEventArgs<Umbraco.Core.Models.IContent> e)
            {
                var Pages = e.SavedEntities.Where(x => x.ContentType.Alias == "DocumentTypeAlias");

                if (Pages.Count() > 0)
                {
                    foreach (var page in Pages)
                    {
                        if (!page.HasIdentity)
                        {
                            page.SetValue("propertyname", "prepopulatedvalueyouwant");
                        }
                    }
                }
            }
        }

Hi there, I know you can do that with the archetype package as it creates its own wrapper round inbuilt fields to extend functionality, but know of no other way out of the box

Hi all,

I am trying to set the default value of a label on a document type call homeFixture and awayFixture. Using the following code when i create a new page using the home & away doctypes it sets the values as expected.

public class DocTypeCreateEventHandler : ApplicationEventHandler
    {
        protected override void ApplicationStarted(UmbracoApplicationBase umbracoApplication, ApplicationContext applicationContext)
        {
            ContentService.Created += ContentService_Created;
        }

        void ContentService_Created(IContentService sender, Umbraco.Core.Events.NewEventArgs<Umbraco.Core.Models.IContent> e)
        {
            if (e.Entity.ContentType.Alias.ToString() == "homeFixture")
            {
                e.Entity.SetValue("location", "Home");
                e.Entity.SetValue("homeTeam", "Cefn Albion FC");
            }
            if (e.Entity.ContentType.Alias.ToString() == "awayFixture")
            {
                e.Entity.SetValue("location", "Away");
                e.Entity.SetValue("awayTeam", "Cefn Albion FC");
            }

        }
    }

However, when the page is saved and published the default values are removed. Can anyone tell me where tim going wrong please?

Thanks

Paul

Hi Paul

I find the best way to set a default value, is to use the EditorModelEventManager.SendingContentModel event

https://our.umbraco.org/documentation/Reference/Events/EditorModel-Events

Here you can set the default values for the properties as the page loads for the editor to edit, so they can see the default values in place, before they save the content.

It's more obvious to the editor then what the default values will be!

    using Umbraco.Core;
    using Umbraco.Core.Events;
    using Umbraco.Core.Models;
    using Umbraco.Web.Editors;
    using Umbraco.Web.Models.ContentEditing;

    namespace My.Namespace
    {
        public class MyEventHandler : ApplicationEventHandler
        {
            protected override void ApplicationStarted(UmbracoApplicationBase umbracoApplication, ApplicationContext applicationContext)
            {
                EditorModelEventManager.SendingContentModel += EditorModelEventManager_SendingContentModel;   
            }            

            private void EditorModelEventManager_SendingContentModel(System.Web.Http.Filters.HttpActionExecutedContext sender, EditorModelEventArgs<Umbraco.Web.Models.ContentEditing.ContentItemDisplay> e)
            { 
                if (e.Model.ContentTypeAlias == "homeFixture")
                {
                    var locationProperty = e.Model.Properties.FirstOrDefault(f => f.Alias == "location");
var homeTeamProperty = e.Model.Properties.FirstOrDefault(f => f.Alias == "homeTeam");
                    if (locationProperty.Value == null || String.IsNullOrEmpty(locationProperty.Value.ToString()))
                    {                  
                        locationProperty.Value = "Home";
                    }
         if (homeTeamProperty.Value == null || String.IsNullOrEmpty(homeTeamProperty.Value.ToString()))
                    {                   
                        homeTeamProperty.Value = "Cefn Albion FC";
                    }
                }
  if (e.Model.ContentTypeAlias == "awayFixture")
                {
                    var locationProperty = e.Model.Properties.FirstOrDefault(f => f.Alias == "location");
var awayTeamProperty = e.Model.Properties.FirstOrDefault(f => f.Alias == "awayTeam");
                    if (locationProperty.Value == null || String.IsNullOrEmpty(locationProperty.Value.ToString()))
                    {

                        locationProperty.Value = "Away";
                    }
         if (awayTeamProperty.Value == null || String.IsNullOrEmpty(awayTeamProperty.Value.ToString()))
                    {                   
                        awayTeamProperty.Value = "Cefn Albion FC";
                    }
                }
            }
        }
    }

Hi Marc,

Sorry for the late reply, competently forgot! I was watching your Anti Patterns talk for CG17 and it prompted me that i haven't replied :).

Thank you for taking the time to provide that detailed answer with code examples :).

I will take a look at this :).

Thanks

Paul
