What's the state of play with “Visual Inheritance”

public class MyForm<MyObject> : Form

public ProductDetail()
{
    InitializeComponent();
}

public ProductDetail(ISupplierController supplierController) : base()
{
    InitializeComponent();
    this.supplierController = supplierController;
}

public NewProduct(ISupplierController supplierController)
    : base(supplierController)
{
    InitializeComponent();
}
