This sample is really nothing more then a slightly modified version of our
Database Sort (With Arrows) sample.
It only exists to illustrate the point discussed in the FAQ.
Notice that even though I do retrieve the ID field, I don't display the values in the table.
Just to show you that you can still use them, I've added an anchor to the other fields so that
if you hover over a record the tooltip that appears will show you the salesman's id.
