How to create a client side Show/Hide panel in ASP.NET
<p>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.</p>

<p>Also, the text "Show" should change to "Hide" without postback.</p>

<p>EDIT: Forgot to mention that I have several such panels in my application.</p>
