little Problem with filtering serverside

Dear sirs

The following connector-script as example:

if($_GET['id'] == "4") { 
   $grid->dynamic_loading(50);
   $grid->set_encoding("iso-8859-1");
   $grid->render_sql("SELECT wonr_intern,CASE termin_stat WHEN '0' THEN 'Nein' WHEN '1' THEN 'Ja' END AS termin_stat FROM sk_auftraege","wonr_intern","wonr_intern,termin_stat"); 
}

If i want to filter i see “0” / “1” and not “Nein” / “Ja”. Can you give me a tip how i can change this?

Got it … “OptionsConnector” is the key
