ProgressChangedEventHandler Delegate

Microsoft Silverlight will reach end of support after October 2021. Learn more.

Represents the method that will handle the ProgressChanged event that is raised when progress is reported by a BackgroundWorker.

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


Public Delegate Sub ProgressChangedEventHandler ( _
    sender As Object, _
    e As ProgressChangedEventArgs _
public delegate void ProgressChangedEventHandler(
    Object sender,
    ProgressChangedEventArgs e



When you create a ProgressChangedEventHandler 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.
