ButtonBase.OnPaint(PaintEventArgs) Method

Definition

Raises the OnPaint(PaintEventArgs) event.

protected:
 override void OnPaint(System::Windows::Forms::PaintEventArgs ^ pevent);
protected override void OnPaint (System.Windows.Forms.PaintEventArgs pevent);
override this.OnPaint : System.Windows.Forms.PaintEventArgs -> unit
Protected Overrides Sub OnPaint (pevent As PaintEventArgs)

Parameters

pevent
PaintEventArgs

A PaintEventArgs 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 OnPaint 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 OnPaint(PaintEventArgs) in a derived class, be sure to call the base class's OnPaint(PaintEventArgs) method so that registered delegates receive the event.
