Data Conversion

• To string – done using .ToString() method
• From string – uses Xaml parser’s logic
• Converters required when not directly assigned in code

One way listens to change notifications

• INotifyPropertyChanged
• DependencyProperty
• INotifyCollectionChanged / IObservableVector

Two way

• UI property Needs to be a DP
• TextBox – Special cased, waits for LostFocus to occur
