I am pretty new to ASP.NET. I need to create a show/hide panel in ASP.NET that holds only text. The panel needs to have sliding effect. I can do with with postback. Is there any built-in control that can do this without postback.

Also, the text “Show” should change to “Hide” without postback.
EDIT: Forgot to mention that I have several such panels in my application.
The ASP.Net Ajax Control Toolkit has the accordian control that has customizable themes and effets, the whole library is well worth a look at.
