Years ago I had to implement a Javascript data grid in a larger web app, but I felt a lot of frustration with the relialibity and (lack of) performance of the top data grid product at that time. I asked my boss if we would give me the time to built my own data grid and I got a YES. Unfortunately, the company I worked for no longer exists, I moved on and I forgot about the data grid project. Years later, while on the road, I suddenly remember it. I rebuilt it from scratch, now version 2 is released and I am very proud of the result. I honestly believe that there is not a single JS data grid out there that has better performance. I hope you guys like the result, which is DataGridXL!
