This presumes you "know" what the line should be. If you want the data from 
a selected line, use the dgHilitedLine(s) to get the line number(s), or as I 
always like to do, use dgHilitedIndex because they remain constant even 
after a sort. dgHilitedLine refers to the visible rows (plus a couple buffer 
rows I understand). dgHilitedIndex refers to any record in the dg data 
array. The index number will remain constant even after a sort (but not of 
course after setting the dgText or dgData).

So if you were looping through all the visible records, use line. If through 
all the records in the data grid, use index.
