getRowId and forEachRow only work with "alert" put ahead

Hello,

I have kind of a strange problem with row IDs, be it with forEachRow or with getRowId, as shows the following example:

<html>
<head>
<link rel="stylesheet" type="text/css" href="codebase/dhtmlxgrid.css">
<script src="codebase/dhtmlxcommon.js" type="text/javascript"></script>
<script src="codebase/dhtmlxgrid.js" type="text/javascript"></script>
<script src="codebase/dhtmlxgridcell.js" type="text/javascript"></script>
<script type="text/javascript">
function doOnLoad() {  
  mygrid = new dhtmlXGridObject('gridbox');
  mygrid.setImagePath("codebase/imgs/");
  mygrid.setHeader("item_nm,item_cd");
  mygrid.setSkin("modern");
  mygrid.init();
  mygrid.loadXML("php/get.php");
  //alert("without this alert getRowId or forEachRow will not work!");
  rId = mygrid.getRowId(0);
  alert(rId); //output: undefined if no alert, rowID if alert
}
</script>
</head>
<body onload="doOnLoad();">
<div id="gridbox" style="width:600px;height:270px;overflow:hidden"></div>
</body>
</html>

(php/get.php just prints some regular xml-code; actually the file is taken from dhtmlxGrid/samples/04_dataprocessor/php/ and the html-code from dhtmlxGrid/samples/04_dataprocessor/01_basic_init.html)

So if I put the (commented out) alert before the call to mygrid.getRowId() (or similar before a call to mygrid.forEachRow(function(rowID) { … } )), everything works fine and I get the row ID (1 for instance), otherwise it just says undefined and all tries of continuing with this value will fail naturally.

Am I doing something wrong or is the mistake somewhere else?

Thanks for your help.

The problem is that you are asking for id before the grid is loaded.
Just modify your code this way:

mygrid.loadXML(“php/get.php”, function(){
//alert(“without this alert getRowId or forEachRow will not work!”);
rId = mygrid.getRowId(0);
alert(rId); //output: undefined if no alert, rowID if alert
});

Thanks, this is working!
