gridview, rowcommand column variable

Zones:

Microsoft Visual C#.Net, .NET Framework 2.0, Visual Studio 2008

Tags:

c#, asp.net 2.x, visual studio 2008 pro, sql 2005 server

have created a database bound gridview fine etc.

when using the rowcommand (i.e. pressing the select link button) and collecting the row selected...I can only select from visible columns?  ... although the information I need, is more of an indexing number within the database and don't particualrly want to display this visually via the gridview.

the problem is that when I make that column non-visible (but still collecting the value via the sql select statement, I cannot pick up that row value from the RowCommand procedure -- make it visible, no problem.

question then is - how do I make a row / column data usable if not wanting to display via the gridview (obviously still displaying the user related informtion via the gridview)

Thank you in advance for your time and efforts with this enquiry.
