my problem is very simple. I wrote my  custom control where I made my own event called DateTapped.

  public event EventHandler<SelectionChangedEventArgs> DateTapped;



  protected void OnDateTapped(DateTime dateTime)        {       

    if (DateTapped != null)            {             

  DateTapped(this, new SelectionChangedEventArgs(dateTime));       


    if (DateTappedCommand != null)       

    {                if (DateTappedCommand.CanExecute(dateTime))                 {                    DateTappedCommand.Execute(dateTime);             







  public ICommand DateTappedCommand        {            get { return (ICommand)GetValue(DateTappedCommandProperty); }            set { SetValue(DateTappedCommandProperty, value); }        }

              public static readonly DependencyProperty DateTappedCommandProperty =            DependencyProperty.Register("DateTappedCommand", typeof(ICommand), typeof(Calendar), new PropertyMetadata(null));


        <customCalendar:Calendar cm:Message.Attach="[Event DateTapped] = [Action EventDateClick($eventArgs)]" >

And when i try to bind event to function in ViewModel it doesn't do anything. When i create code in code behind everything it's ok. Could you tell me how to do that in ViewModel in caliburn.micro ?

since its a custom control you might need to create a convention for it.

But how? I'm searching for solution for two days and still no idea. Could you help me?

And other bindings with the ViewModel are working?

Maybe you can create a sample to show your issue, as at the moment we can only guess.
