I've just started using EhLib's dbgrid which has some really nice built-in search functionality.  One feature it has emulates excel's filter option, providing a drop-down filter selection box for all unique values displayed in each column of the grid - but it needs a custom written unit to handle a dbisam database.  I'm wondering if anyone has written such a unit for EhLib?  Unfortunately writing this translation unit is beyond my rather rudimentary coding abilities.
Thanks
