Edit Question
Title
Body
Let's say I have a class: class Foo { public string Bar { get { ... } } public string this[int index] { get { ... } } } I can bind to these two properties using "{Binding Path=Bar}" and "{Binding Path=[x]}". Fine. Now let's say I want to implement INotifyPropertyChanged: class Foo : INotifyPropertyChanged { public string Bar { get { ... } set { ... if( PropertyChanged != null ) { PropertyChanged( this, new PropertyChangedEventArgs( "Bar" ) ); } } } public string this[int index] { get { ... } set { ... if( PropertyChanged != null ) { PropertyChanged( this, new PropertyChangedEventArgs( "????" ) ); } } } public event PropertyChangedEventHandler PropertyChanged; } What goes in the part marked ????? (I've tried string.Format("[{0}]", index) and it doesn't work). Is this a bug in WPF, is there an alternative syntax, or is it simply that INotifyPropertyChanged isn't as powerful as normal binding?
