Another DataGrid Question

[LunchnMeets at aol.com]

Hi Everyone

First of all thanks to Zryip for the answer to my last grid question. Now 
that problem is solved, but I have another.

I have a dataGrid with 8 columns and 1000 rows. Knowing the data of a line 
of column 2, I need to retrieve the data of column 1 of that line. I don't 
want to change anything in the dataGrid while doing this. How is this best 
accomplished? If it helps Column 1 is titled Securities and column 2 is titled 
Symbol.

Thanks in advance for your continued assistance.
