Has anyone here used Sigma Grid for JavaScript-based data grids? It was the only grid I could find that would allow fast data entry and use of the keypad, but before we spend a lot of development time I wanted to learn about the community's experience with it.
(Note: we need dozens of fast, sortable, and editable grids that can be used with the arrow keys and minimal mouse use ... otherwise we'd just pop in an ASP.NET control)
We decided to go with Sigma Grid after the folks at the other ASP.NET control companies said they couldn't provide the required functionality.
