Radionbuttons checking in ASP.NET
<p>It's possible check if one of radio buttons named of 'foo' is selected? For example:</p>

<pre><code>&lt;input type="radio" name="foo" id="baa"  value="..."   runat="server" /&gt;
&lt;input type="radio" name="foo" id="baa1" value="....." runat="server" /&gt;
</code></pre>

<p>the question is: Is there some <code>&lt;asp:..</code> that can test if one(not both, only one can be selected) of above checkbox if selected?</p>

<p>I hope this is clear. Thanks in advance.</p>
