(data grid) is there a good workaround for obtaining other column values in FillInData for a Data Grid Table?

[Mike Bonner]

If you set a custom behavior for the column you want the sum in, and
where it has the section for filling data, put

   put the dgDataOfIndex[ the dgIndex of me] of the dgControl of me
into theDataA
   set the text of field 1 of me to (theDataA["Col 2"] + theDataA["Col 3"])

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.

Now the data set is getting so large that this is too slow, looping through once to calc, then again for the grid. So we're thinking doing the calculation in FillInData would be more efficient. If possible.
