I was wondering if there was a way to display the first 3 key columns in the grid when the user scrolls from left to right while looking at the other columns. I would like to still keep the outlook group by functionality.
The functionality you're looking for is alternately called "fixed headers" or "fixed columns". Our online help documentation on NetAdvantage for .NET 2008 Volume 3 provides information on how to enable this functionality at either design-time or in code.
