   Bind("VOID") %&gt;' AutoPostBack="True" 
           oncheckedchanged="RadioButton1_CheckedChanged"
                                       GroupName='&lt;%# BIND("WallstreetID")
   %&gt;' /&gt;
                               &lt;/ItemTemplate&gt;
          protected void RadioButton1_CheckedChanged(object sender, EventArgs e)
          {
