I have the following code which I hoped would force all Folder media items to appear first in their list.

public class CreateEvent : ApplicationEventHandler
{
    protected override void ApplicationStarted(UmbracoApplicationBase a, ApplicationContext c)
    {
        MediaService.Creating += MediaService_Creating;
    }

    void MediaService_Creating(IMediaService sender, NewEventArgs<IMedia> e)
    {
        if (e.Entity.ContentType.Alias.EndsWith("Folder"))
        {
            e.Entity.SortOrder = 0;
        }
    }
}

Unfortunately, Umbraco seems to ignore the value I am setting. Presumably because it is working out the SortOrder after this event is fired.

Any ideas how I can overcome this? Ideally, I would like to be able to set the SortOrder and not then have to reload the content tree :)
