PrintDocument.PrintPage override

Question

I need to pass a parameter to the event PrintPage of the PrintDocument relative to my PrintPreviewDialog in some way.

I tought to inherit PrintDocument class adding to it a property with the parameter I need, creating MyPrintDocument class. Then, I would like to create MyPrintPreviewDialog class, in which I could override the Document property declaring it of MyPrintDocument type.

The problem is that the Document property is not overridable and if I declare it Shadows the PrintPageEvent doesn't raise.

Do you have a better idea? Thank you
