    Show dialog on ContentSavingNotificationHandler.HandleAsync

    Hi, I have some problems and have no idea, how to show a dialog popup on SavingContent event in method HandleAsync. Some code here:

         public class ContentSavingNotificationHandler : INotificationAsyncHandler<ContentSavingNotification>
  {
    private readonly IContentService contentService;
    private readonly IEventService eventService;
    public ContentSavingNotificationHandler(IContentService contentService
      , IEventService eventService)
    {
      this.contentService = contentService;
      this.eventService = eventService;
    }
    public Task HandleAsync(ContentSavingNotification notification, CancellationToken cancellationToken)
    {
      if(eventService.GetSomething())
      // want to show popup from here
    }
  }

    has somebody idea how to do it?

    Hi there,

    Could you elaborate on what exactly you are trying to achieve?

    As far as I know, it's not a thing to trigger a popup in the frontend from an event in the backend, especially because an event can also be fired from background processes.

    hi, thanks you for your interest. What I want to do? I want to show a dialog window ( just after press save/publish button, and before save method ), where user can do some confirmation ( if clicks Ok - save procedure continues, else stop - save process is canceled )...

    Ah, I see. Well once the users clicks on save or save & publish, this action is set in motion and once your event handler triggers, it's too late to give your users any options.

    To change the behaviour on save or on save & publish, you'd have to do some magic to the buttons in the umbraco backoffice.

    Here is an example of a plugin that changes the behaviour on certain buttons by intercepting the request that gets the html for the button and replacing it with a new implementation.

    It's a complicated process and should be considered a hack. You may want to consider an alternative.
