I needed a grid that was very flexible but could work in unbound mode. I looked a long time and tried at least 5 different grid tools before settling on Syncfusion's GridControl. I wasn't even sure that it could meet my unique needs but it has and even exceeded my expectations. It is very powerful, extensible, and flexible resulting in my application having impressive capabilities. Along the way Syncfusion's support did a good job of getting me past sticking points. I currently own other compenents from other companies as well. And while they each have their strengths, I am very satified in the price/performance of each of the Synfusion components I use. And I can say with certainty that if you want a grid control to work in unbound mode, you won't find a better one that the grid control from Syncfusion!
