Select list dependent on textbox

Question

Hi,
I've a requirement to put together a cascading select list. The only exception is that the first select list is a textbox instead of a select list. How to create a select list that is dependent on the textbox? Is there a way to do this in APEX without resorting to AJAX? Is there an example out there?
Thanks

Hi
Try this courtesy of Carl Backstrom...
Create an hidden item called TEMPORARY_ITEM.
Try this for the js:
  function get_AJAX_SELECT_XML(pThis,pSelect){  
     var l_Return = null; 
     var l_Select = $x(pSelect); 
     var get = new htmldb_Get(null,$x('pFlowId').value,'APPLICATION_PROCESS=ap_str_typ_lov',0);
get.add('TEMPORARY_ITEM',pThis.value);
     gReturn = get.get('XML'); 
     if(gReturn && l_Select){ 
         var l_Count = gReturn.getElementsByTagName("option").length; 
         l_Select.length = 0; 
         for(var i=0;i<l_Count;i++){ 
             var l_Opt_Xml = gReturn.getElementsByTagName("option");
appendToSelect(l_Select, l_Opt_Xml.getAttribute('value'), l_Opt_Xml.firstChild.nodeValue)
get = null;
function appendToSelect(pSelect, pValue, pContent) { 
var l_Opt = document.createElement("option");
l_Opt.value = pValue;
if(document.all){/* why is ie different ask bill */ 
pSelect.options.add(l_Opt);
l_Opt.innerText = pContent;
}else{ 
l_Opt.appendChild(document.createTextNode(pContent));
pSelect.appendChild(l_Opt);
And then amend your On Demand process to this:DECLARE
l_counter NUMBER;
l_o_name VARCHAR2(2000);
BEGIN
OWA_UTIL.mime_header('text/xml', FALSE);
HTP.p('Cache-Control: no-cache');
HTP.p('Pragma: no-cache');
OWA_UTIL.http_header_close;
HTP.prn('<select>');
FOR rec IN (select str_typ_desc from vw_dime where street_name like upper(:P7_STREET_NAME) || '%'
ORDER BY 1)
LOOP
HTP.prn('<option value="' || rec.str_typ_desc || '">' || rec.str_typ_desc || '</option>');
END LOOP;
HTP.prn('</select>');
END;
Then change your javascript call to this...onKeyUp="get_AJAX_SELECT_XML(this, 'P7_STREET_NAME')"
Let me know How you get on.
Cheers
Ben
