Hello,

I've got a media item, and I want to add some business logic that it can't be deleted if it's related to some other (custom) tables. If the delete is canceled I'd like to inform the user the delete action has been canceled. Can I call the speechBubble method or some other javascript method to inform the user? My code now looks like this:

public class ProjectApplicationBase : ApplicationBase
    {
        public ProjectApplicationBase ()
        {
            #region Events

            Media.BeforeDelete += new Media.DeleteEventHandler(Media_BeforeDelete);

            #endregion
        }

        protected void Media_BeforeDelete(Media sender, umbraco.cms.businesslogic.DeleteEventArgs e)
        {
            int countValue = Convert.ToInt32(sender.getProperty("mediaCount").Value);

            if (countValue > 0)
            {
                //Some code to show a pop-up the item has not been deleted.

                e.Cancel = true;
            }
        }
    }
