What is the difference between <asp:Panel > and <asp:PlaceHolder > in ASP.NET? When should you use one over the other?
<asp:Panel >
<asp:PlaceHolder >
A panel expands to a span (or a div), with it's content within it. A placeholder is just that, a placeholder that's replaced by whatever you put in it.
