Why this works out of UpdatePanel but not inside UpdatePanel?
<p>I have copy and paste this Alert Class:
<a href="http://madskristensen.net/post/JavaScript-AlertShow%28e2809dmessagee2809d%29-from-ASPNET-code-behind.aspx" rel="nofollow">http://madskristensen.net/post/JavaScript-AlertShow%28e2809dmessagee2809d%29-from-ASPNET-code-behind.aspx</a></p>

<p>It works except with a button inside an update panel but it shows no error. The asp code inside is executed but nothing shows up on client side. </p>
