The Controls Collection is Empty for my ASP.NET Panel on Postback

Hi, Everybody!

I have this ASP.NET panel (id="myPanel" runat="server") onto which I dynamically add DIVs, TABLEs, TRs, TDs, INPUTs (e.g., radio buttons, text boxes, etc.), SELECTs, etc.  The page is rendered beautifully.

However, on postback, the Controls collection of "myPanel" contains NO controls (Count = 0).  Setting the ID property and setting the "runat" attribute to "server" for each control does not work.

What am I missing?...  HELP!
