    Custom handlers

    Hello, I need help to realize, for an Umbraco 7 website, a custom handler to auto-fill a property on new node creation.

    For example...every time I create a new node I immediately must:

    • Check if exist a "title" property and automatically assign the node name value
    • Check if exist a "date" property and automatically assign the Now() value

    I made several attempts but they don't work Can anyone help me? Thank you Adriano

    Can you use ContentService Saving for this?

    Yeah...I found the solution last week exactly with the contentService.

    This is an example code:

    using System;
using Umbraco.Core;
using Umbraco.Core.Events;
using Umbraco.Core.Models;
using Umbraco.Core.Publishing;
using Umbraco.Core.Services;

namespace myNameSpace

{
    public class myHandler : ApplicationEventHandler
    {

        protected override void ApplicationStarted(UmbracoApplicationBase umbracoApplication, ApplicationContext applicationContext)
        {
            ContentService.Saving += ContentServiceSaving;
        }

        private void ContentServiceSaving(IContentService sender, SaveEventArgs<IContent> args)
        {
            foreach (var node in args.SavedEntities)
            {
                foreach (var property in node.Properties)
                {
                    if ((property.Alias == "title") && (String.IsNullOrEmpty(property.Value.ToString()))) 
                    { 
                        property.Value = node.Name; 
                    }

                    if ((property.Alias == "date") && (String.IsNullOrEmpty(property.Value.ToString())))
                    {
                        property.Value = DateTime.Now;
                    }
                }
            }
        }
    }
}

    That's all!!!

    Glad to help.

    Adriano
