Namespace: System.Net
Assembly: System.Net (in System.Net.dll)
Syntax
'Declaration
Protected Overridable Sub OnDownloadProgressChanged ( _
e As DownloadProgressChangedEventArgs _
)
protected virtual void OnDownloadProgressChanged(
DownloadProgressChangedEventArgs e
)
Parameters
- e
Type: System.Net.DownloadProgressChangedEventArgs
A DownloadProgressChangedEventArgs object containing event data.
Remarks
Classes that inherit from this class can override this method to perform additional tasks when the DownloadProgressChanged event occurs.
Raising an event invokes the event handler through a delegate.
The OnDownloadProgressChanged method also allows derived classes to handle the event without attaching a delegate. This is the preferred technique for handling the event in a derived class.
Notes to Inheritors
When overriding OnDownloadProgressChanged in a derived class, be sure to call the base class’s OnDownloadProgressChanged method so that registered delegates receive the event.
