title: how to access generated groupname for asp radiobutton
body: <p>I need to access radiobutton groupname in my jquery.  However, groupname that's rendered for an asp radiobutton is kind of different.  Example:</p>
  
  <pre><code>&lt;asp:RadioButton runat="server" GroupName="payment" ID="creditcard" Checked="true" value="creditcard" /&gt;
  </code></pre>
  
  <p>will generate:</p>
  
  <pre><code>&lt;input type="radio" checked="checked" value="creditcard" name="ctl00$ContentPlaceHolder1$payment" id="ctl00_ContentPlaceHolder1_creditcard"&gt;
  </code></pre>
  
  <p>I can't work with &lt;%=creditcard.GroupName%> in jquery.  Is there a way I can get the generated groupname or name for it?</p>
