>How can I use the List form (frmDataListForm) to show more than 1 column with respective headers ?
You need to subclass. Look at the "frmOrderListRecords" in the AppForms class library of the sample application. This is used with the order.scx form - it will give you the clues you need. To get the effect you are after, you can subclass the standard list form and add a new grid, specified to your requirements - the standard listform is just way too basic. Whilst you're at it, you may as well add incremental searching to your list as well.
