Methods
OnPropertyChanged(string)
Raises the PropertyChanged event to notify listeners that a property value has changed.
Declaration
protected virtual void OnPropertyChanged(string propertyName)Parameters
propertyName
The name of the property that changed. This value is passed to event handlers to identify the property that was updated.
Remarks
Override this method in a derived class to provide custom logic when a property value changes. This method is typically called by property setters to implement the INotifyPropertyChanged pattern.
Events
PropertyChanged
Occurs when a property value changes.
Declaration
public event PropertyChangedEventHandler PropertyChangedEvent Value

Remarks
This event is typically raised by classes that implement the INotifyPropertyChanged interface to notify clients, such as data-binding frameworks, that a property value has changed. Handlers attached to this event receive the name of the property that changed in the PropertyChangedEventArgs parameter.
