Assembly: KGySoft.CoreLibraries (in KGySoft.CoreLibraries.dll) Version: 6.0.1

Syntax

C++

Copy

public event PropertyChangedEventHandler PropertyChanged

Public Event PropertyChanged As PropertyChangedEventHandler

public:
virtual  event PropertyChangedEventHandler^ PropertyChanged {
	void add (PropertyChangedEventHandler^ value);
	void remove (PropertyChangedEventHandler^ value);
}

abstract PropertyChanged : IEvent<PropertyChangedEventHandler,
    PropertyChangedEventArgs>
override PropertyChanged : IEvent<PropertyChangedEventHandler,
    PropertyChangedEventArgs>

Value

Type: System.ComponentModelPropertyChangedEventHandler

Implements

INotifyPropertyChangedPropertyChanged

Remarks

Note
The PropertyChanged event uses the PropertyChangedEventHandler delegate in order to consumers, which rely on the conventional property changed notifications can use it in a compatible way. To get the old and new values in an event handler you can cast the argument to PropertyChangedExtendedEventArgs or call the TryGetOldPropertyValue and TryGetNewPropertyValue extension methods on it.
