Namespace: Microsoft.Windows.Design.Model
Assembly: Microsoft.Windows.Design.Interaction (in Microsoft.Windows.Design.Interaction.dll)
Syntax
'Declaration
Public MustOverride Event PropertyChanged As PropertyChangedEventHandler
'Usage
Dim instance As ModelItem
Dim handler As PropertyChangedEventHandler
AddHandler instance.PropertyChanged, handler
public abstract event PropertyChangedEventHandler PropertyChanged
public:
virtual event PropertyChangedEventHandler^ PropertyChanged {
void add (PropertyChangedEventHandler^ value);
void remove (PropertyChangedEventHandler^ value);
}
JScript does not support events.
Implements
INotifyPropertyChanged.PropertyChanged
Remarks
This event implements the INotifyPropertyChanged interface. This event can be used to tell when a property on the model changes. It is also useful because INotifyPropertyChanged can be used by the data binding features of Windows Presentation Foundation (WPF).
You should disconnect events from items when you are finished with them. Otherwise, you can prevent the item from being clean up during garbage collection.
