The EditorZoneBase that contains the EditorPart control is a null reference (Nothing in Visual Basic).

In addition to calling the base OnPreRender method, the OnPreRender method also checks the Display property. If the value is false, meaning that the control should not be displayed, then the Visible property is also set to false.
