Extracting data grid get column data

[Jim Ault]

Logically it would make sense, but the reality is that 'filter' is  
lightning fast so you would not likely be able to measure any speed  
difference.  Of course, very large data sets need to be measured, but  
then DataGrid would be the far slower part of the process.
