I have recently upgraded from using VS Flex Grid with Visual Basic to using the new ComponentOne Flex Grid with .NET and I am considerably impressed with the new package. It is an added bonus that all the other controls come with the studio. I have also started using the charting component and have not yet found anything which either of these controls cannot do. They are easy to use and their are extensive samples to refer to in most cases. Highly recommended!
