Jak dodać formant do kontenera w odziedziczonym WinFormie

Mam formę podstawową w innym projekcie, który wymusza taki sam wygląd i działanie wszystkich naszych programów WinForm. Odziedziczyłem po tym BaseFormie, aby stworzyć własny szablon BaseView. Ten mój szablon ma dodatkowe kontrolki, takie jak ProgressBar, Timer i TableLayoutPanel.

Teraz chcę odziedziczyć po moim BaseView i użyć Projektanta, aby dodać moje kontrolki specyficzne dla programu, jednak nie mogę wrzucić do niego żadnych elementów, takich jak Panele lub inne Kontrolki. Próbowałem kilku sugestii, takich jak upewnienie się, że komponenty formularza podstawowego są publiczne, ale bezskutecznie - większość właściwości TLP jest nadal wyszarzona.

Czy ktoś może dać mi jakieś sugestie? Wielkie dzięki!

partial class BaseView
{
    /// <summary>
    /// Required designer variable.
    /// </summary>
    private System.ComponentModel.IContainer components = null;

    /// <summary>
    /// Clean up any resources being used.
    /// </summary>
    /// <param name="disposing">true if managed resources should be disposed; otherwise, false.</param>
    protected override void Dispose(bool disposing)
    {
        if (disposing && (components != null))
        {
            components.Dispose();
        }
        base.Dispose(disposing);
    }
