How To Raise Property Changed events on a Dependency Property?
- by Muad'Dib
OK, so I have this control with two properties. One of these is a DependencyProperty, the other is an "alias" to the first one. What I need to be able to do is raise the PropertyChanged event for the second one (the alias) when the first one is changed.
NOTE: I am using DependencyObjects, not INotifyPropertyChanged (tried that, didn't work because my control is a sub-classed ListView)
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 I can raise PropertyChanged events on multiple properties from one setter. I need to be able to do the same thing, only using DependencyProperties.
