The demo application was more of a "What can be done" rather than what actually should be done. I can think of many real time applications where the examples I used would be needed, however as a demonstration it's probably not the best example of using AJAX :) Steve Cooney you are absolutely correct.

But, you don’t update the database, you INSERT a record. I would like to know how to select a record in a dbgrid, and get the field values in editfields, change them and update that record. And if you show how to do that, I guess, deleting a record will not be a problem either. Thanks, stefan great example. But, you don’t update the database, you INSERT a record.

You are sending a payload back to the webserver, its instantiating the page and calling a function, returning the result and injecting it into the page asynchronously, just to add text to a control!!. You only need client side javascript to do that, AJAX is misapplied here. A real world application would not do that. Secondly the return(false) javascript ststement is not needed if you properly set the button type to btNormal instead of the default btSubmit.
