PropertyChangedEventHandler Delegate

Represents the method that will handle the PropertyChanged event raised when a property is changed on a component.

Namespace:  System.ComponentModel
Assembly:  System (in System.dll)

[HostProtectionAttribute(SecurityAction.LinkDemand, SharedState = true)]
public delegate void PropertyChangedEventHandler(
	Object sender,
	PropertyChangedEventArgs e
)

Parameters

sender
Type: System.Object

The source of the event.

e
Type: System.ComponentModel.PropertyChangedEventArgs

A PropertyChangedEventArgs that contains the event data.

When you create a PropertyChangedEventHandler delegate, you identify the method that will handle the event. To associate the event with your event handler, add an instance of the delegate to the event. The event-handler method is called whenever the event occurs, unless you remove the delegate. For more information about event-handler delegates, see Events and Delegates.

NoteNote

The HostProtectionAttribute attribute applied to this type or member has the following Resources property value: SharedState. The HostProtectionAttribute does not affect desktop applications (which are typically started by double-clicking an icon, typing a command, or entering a URL in a browser). For more information, see the HostProtectionAttribute class or SQL Server Programming and Host Protection Attributes.
