Can I create a Custom Tab Page in c#?

I've seen examples of custom tab controls online, but I want to be able to create custom tab pages, that could be added in at run-time. (For instance, a plugin to my app adds 1-2 tabs to my main tab control.)

So far I have some code, but it doesn't display much in the designer:

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Drawing;
using System.Data;
using System.Text;
using System.Windows.Forms;

namespace ProjectTracker
{
    [Designer(typeof(TabPage))]
    [ToolboxBitmap(typeof(TabPage))]
    public partial class ProjDocsPage : TabPage
    {
        private AutoScaleMode autoScaleMode;
        public AutoScaleMode AutoScaleMode
        {
            get { return autoScaleMode; }
            set { autoScaleMode = value; }
        }

        public ProjDocsPage()
        {
            InitializeComponent();
        }

    }
}

Correct, because at runtime, I'm looking at the app.

What I'm asking is, can I see them in the designer at design time? Adding controls to the tab in the designer, then at Runtime, the TabController gets any tabs I tell it to dynamically.

No, they wouldn't. But they may do

The Designer executes the control's constructor, but nothing else. If you add the tabs in the constructor (in your own *.cs, rather than the *.designer.cs files) then they will appear. But make sure you don't do anything expensive or anything requiring dependencies in the constructor otherwise the Designer might throw a wobbly and not display it at all.
