By overriding of the method
OnPaint in the derived class. If you need more room for this declaration, you would also need to adjust the client size using y overriding the method
SetClientSizeCore.
Please see:

Instead of overriding of the method
OnPaint you can also handle the event
Paint, but it makes not much sense if you have to create a derived class anyway:

When rendering, don't repeat a common mistake: don't create an instance of the class
System.Drawing.Graphics, instead, use the one passed in the event argument parameter.
