How to reproduce a forum/twitter-like UI on Winform

[TruffleWorm]

As a classic forum, threads and replys are displayed on a page, with dark and light and dark and light backcolor.

I am trying to write a client of a forum on windows using winform. It is

At first, I have tried this way:

1. 
   Add a big panel to the form, let's call it the PARENT PANEL.
   
   
2. 
   Add small panels to the big panel like this:
   
   panel1.Visible = false;
   for (int i=0; i<5;i++)
   {
   Panel parent = new Panel();
   parent.Height = 800;
   Random ra = new Random();
   TextBox p = new TextBox();
   p.Text = "fehsuifq";
   p.Multiline = true;
   p.WordWrap = true;
   p.Dock = DockStyle.Fill;
   parent.BackColor = Color.FromArgb(ra.Next(0, 254), ra.Next(0, 254), ra.Next(0, 254));
   p.BorderStyle = BorderStyle.None;
   p.ReadOnly = true;
   p.TabStop = false;
   p.BackColor = this.BackColor;
   parent.Controls.Add(p);
   parent.Dock = DockStyle.Top;
   panel1.Controls.Add(parent);
   }
   panel1.Visible = true;

Every panel(tenicially, a control) displays a thread's text and images and others details(like authors or avator). Images are not shown until it is clicked. when the image is clicked, it is loaded and the controls's height will change as result. The PARENT PANEL will contains hundreds of these controls since there will be so many threads. It is and have to be scrollable, obviously.

But if I put a textbox in the control, the scroll wheel no longer work on the PARENT PANEL.If I use a label, it is not selectable.

I think this way can't be more stupid, completely.

So I am looking for a better to do this job, to display hundreds or even thousands threads/replys on winform, which is:

1. the height is dynamic, because the images inside will not load until it is clicked.
2. selectable
3. the PARENT PANEL can response to the mouse's wheel, just like twitter, forums.

So that I can use my scroll wheel to browse all the replys at one time. The loading is a background work.
