hi
Frank
i have used gridfooter.vcx in my project now very nice working here
first i had some problem . what i say you.

1. which alias we can want to use in gridfooter, if there are no records in alias
2. if we drag colums of parent grid example, column1,cloumn3,column2

i found two bugs, but these are miner bugs here
you can also solve this bugs too
use this gridfooter excellent working properly
