Getting xml string or csv from grid data

The documentation is saying that I should be able to get an XML string of the grid data with

mygrid.setSerializationLevel(true,true); var myXmlStr = mygrid.serialize(); alert (myXmlStr);

I should be able to get a csv with

var gridcsv=mygrid.serializeToCSV(); alert(gridcsv);

neither has any data.

How do I get the data out of the dhtmlxgrid? Do you have an example showing how to get the data from the grid as a string? Is that feature available in the open source version?

Those features are available in PRO version only. You can find examples here
