When I create a class whose base class is "Control" and then use the visual designer to add an instance of the class to the column of a grid, why does the control instance not conform its width and height to the Grid.RowHeight and Column.Width like, say, a TextBox does?

Is this expected behavior? If so, it is annoying, :-) since a column's controls' height and width are readonly. The only way to get the instantiated class to be the right size is to add it to the grid column programmatically. I can work around it but I would rather not have to. :-) Am I missing sonmething here?

Thanks,
Bill
