Re: Grid from TexBoxes is Slow

Thanks Adrian, I'll look at the stacked grids and HTML. I've been wanting to
brush up on my web UI skills, so maybe that's the way to go.  Our core
product is intranet, so time improving my DHTML and Javascript will be well
spent.

Although this is a pet project, I do intend to offer it for use in my main
application, but many of our clients are running SQL Server Express, and
don't enjoy the full benefits of Reporting Services, and none of the
benefits of Integration Services.  BTW, my grid is for editing text (CSV)
file layouts and viewing the files themselves.
