Should work fine. Not positive this is the best method, but seems to
work dandy fine with small datasets. Haven't tried it with big ugly
datasets.
If you didn't want to fetch all of the data for the entire row you
could use GetDataOfIndex. GetDataOfIndex only retrieves the value of a
specific column.
put the dgIndex of me into theIndex
set the text of field 1 of me to (GetDataOfIndex(theIndex, "Col 2") +
GetDataOfIndex(theIndex, "Col 3"))
