               for (int i = 0; i < ChklistDomain.Items.Count; i++)
               {
                   if (ChklistDomain.Items[i].Selected == true)
                       count++;
               }
               if (count == 0)
               {
                   ScriptManager.RegisterStartupScript(this, this.GetType(), "key", "alert(' Atleast select one domain !')", true);

               }
               else

{
  var c = document.getElementsByTagName('input');
  for( var i = 0; i < c.length; i++ )
  {
    if( c[i].type.toLowerCase() == 'checkbox' && c[i].checked )
    {
      // A checkbox was checked, good user
      return( true );
    }
  }
  // No checkbox checks, bad user
  return( false );
}
