Someone must know how to do this?

Hi Ayo,

I guess you can use an event for this - if you have access to Umbraco.TV, there's a series of videos explaining how to do something like that:

Umbraco.TV Developer/Events

Hope that helps,

Hi Chriztian....

I know how to use the events, what I need help with is the santax... heres what I mean.

    void ContentService_Saving(IContentService sender, Umbraco.Core.Events.SaveEventArgs<IContent> e)
    {
        foreach (var myNode in e.SavedEntities.Where(x => x.HasProperty("propertyName")))
        { 
            //if (myNode.GetPropertyValue("propertyName").hasChanged)
    // then
    //bla bla bla

        }
    }

Also is there a version of this method that is a single IContent object rather than a list, In previous versions was this not the case?

Thanks

I found this method

IContent.IsPropertyDirty() can't find any documentation on it though... any ideas?

This is the answer I was looking for..................... why is there no documentation on this method :-/

foreach (var myNode in e.SavedEntities.Where(x => x.HasProperty("myproperty")))
            {
                if (myNode.IsPropertyDirty("packageStatus"))
                {
                           //perform action
                }
            }

I found out that in the ContentService_Publishing you can compare current value and old one for example:

 private void ContentService_Publishing(PublishEventArgs<IContent> args, ApplicationContext applicationContext)
    {
        var contentService = applicationContext.Services.ContentService;

        foreach (var item in args.PublishedEntities)
        {
            var name = item.Name;
            var id = item.Id;
            var oldName = contentService.GetById(id).Name;

            if (name != oldName)
            {
                //do something
            }

        }

    }

And register your method here:

protected override void ApplicationStarted(UmbracoApplicationBase umbracoApplication, ApplicationContext applicationContext)
    {
        ContentService.Publishing += (sender, arg) => ContentService_Publishing(arg, applicationContext);

    }

is working on a reply...
