How To Raise Property Changed events on a Dependency Property?

I have a control with two properties. One is a DependencyProperty, the other is an "alias" to the first one. How do I raise the PropertyChanged event for the second one (the alias) when the first one is changed.

NOTE: I'm using DependencyObjects, not INotifyPropertyChanged (tried that, didn't work because my control is a ListVie sub-classed)

Something like this.....

protected override void OnPropertyChanged(DependencyPropertyChangedEventArgs e)
{
    base.OnPropertyChanged(e);
    if (e.Property == MyFirstProperty)
    {
        RaiseAnEvent( MySecondProperty ); /// what is the code that would go here?
    }    
}

If I were using an INotify I could do like this...

public string SecondProperty
{
    get
    {
        return this.m_IconPath;
    }
}

public string IconPath
{
    get
    {
        return this.m_IconPath;
    }
    set
    {
        if (this.m_IconPath != value)
        {
            this.m_IconPath = value;
        this.SendPropertyChanged("IconPath");
        this.SendPropertyChanged("SecondProperty");
        }
    }
}

Where can I raise PropertyChanged events on multiple properties from one setter? I need to be able to do the same thing, only using DependencyProperties.

1. Implement INotifyPropertyChanged in your class.

2. Specify a callback in the property metadata when you register the dependency property.

3. In the callback, raise the PropertyChanged event.

Adding the callback:

public static DependencyProperty FirstProperty = DependencyProperty.Register(
  "First", 
  typeof(string), 
  typeof(MyType),
  new FrameworkPropertyMetadata(
     false, 
     new PropertyChangedCallback(OnFirstPropertyChanged)));

Raising PropertyChanged in the callback:

private static void OnFirstPropertyChanged(
   DependencyObject sender, DependencyPropertyChangedEventArgs e)
{
   PropertyChangedEventHandler h = PropertyChanged;
   if (h != null)
   {
      h(sender, new PropertyChangedEventArgs("Second"));
   }
}
