>Is there a tool, OCX, class, anything, that will allow the field order in a grid to be changed based on clicking on the column heading???

There have been many inquiries to this in the past. Basically what you can do is create your own class subclassed from HEADER and add create code for the click event. Then when you build your grid, you can dynamically drop the default header, and add your custom class. This way, you can add your own properties, methods, etc to your class and allow control to however you see fit.
