I think you will be happy with HTTPService.
Specify resultFormat="e4x" in the HTTPService tag, otherwise flex converts the xml into an nested mx:Object structure. I find e4x XML much easier to work with. Don't bind directly to lastResult. It is too hard to debug. Instead use a result handler, and set an instance variable value(XMLListCollection) to event.result.STAFFREC in that, and bind the DataGrid dp to the instance variable. In the handler, you can trace the instance variable.toXMLString() to see exactly what yo have, and how to set the DataGridColumn dataField or labelFunction. I've written sample code tor this so many times I don't want to do it again right now, but post if you need more detail.

I have a flex DBGrid client that was supposed to consume a web service client. After much tweaking and coding. No success. I switched to HTTPService and this was returning xml results. But when DBGrid accepts the results they are all listed ONLY in row 1 of the DBGrid. Below is the mxml application as well as the web service I 1st used and finally the httpservice routine done in C# 2.0 Any help will be appreciated.
