It's been many years since I used WinForms but if I remember visual inheritance and WinForms designer support in Visual Studio don't work the same as you would be used to from VFP or VB6. Basically you have to programmatically add designer support, or as you say programmatically update any control properties you want to change.
WPF and its successors are much better in this regard.
