>>>>I need to change sorting of records when user clicks on a column header of a grid. As far as I know how to do it, you have to replace "Header1" from the column object and replace it with your own custom object. The problem I am having is that it works when grid has no columns and you build it from "scratch."

>>>It would help if you said which error are you getting. I don't remember whether I've done that in 6, or started with 7, but I think you don't need the removeobject line. If you watch it in the debugger, the moment you remove the header, a new one is inserted instead of it. But when you add a header, the old one is automatically removed.

Great. This works, that is, I don't get the error any more. Thank you very much!
