PictureBox.OnLoadProgressChanged(ProgressChangedEventArgs) Method

Definition

Raises the LoadProgressChanged event.

protected:
 virtual void OnLoadProgressChanged(System::ComponentModel::ProgressChangedEventArgs ^ e);
protected virtual void OnLoadProgressChanged (System.ComponentModel.ProgressChangedEventArgs e);
abstract member OnLoadProgressChanged : System.ComponentModel.ProgressChangedEventArgs -> unit
override this.OnLoadProgressChanged : System.ComponentModel.ProgressChangedEventArgs -> unit
Protected Overridable Sub OnLoadProgressChanged (e As ProgressChangedEventArgs)

Parameters

e
ProgressChangedEventArgs

A ProgressChangedEventArgs that contains the event data.

Remarks

Raising an event invokes the event handler through a delegate. For more information, see Handling and Raising Events.

The OnLoadProgressChanged 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 OnLoadProgressChanged(ProgressChangedEventArgs) in a derived class, be sure to call the base class' OnLoadProgressChanged(ProgressChangedEventArgs) method so that registered delegates receive the event.
