Hello there,
I tested, and tried the DataGridView Extension, and it's really great.
I'm considering to buy the Gold Version, however i'm a bit astonished that here in the Forum, there are no active posters.
I'm also astonished that this great product isn't more popular (as of now), as of the little amount of Posts here in the last months.
Hope that you will gain more Users soon, and hope you have the time/energy to continue to develop.
The only negative thing i can say so far is ,that with a huge amount of Data, the Export to Excel is quiet slow, however this might be a problem of the way the data is transfered between the application and Excel itself, and might not be speed up by itself.
As an alternative the inclusion of an Excel Exporter that works with the Excel XML would maybe speed up that process and would not need the Office/Excel .dll's nor an installed Excel on the machine.
Examples are on codeproject.net, if you are interested.
Apart from that, i really like your approach, and everything looks very clean and well designed.
Hope to get some Feedback ,about the Future of this product from the developers.
Cheers,
Markus.
