I chose Syncfusion suite because of it's extensive functionality on WPF grid controls that meet most of my expectations. After I started using it, I'm very impressed by its functionality, and more importantly their support team who offers very helpful support while I'm learning on utilising grid controls for my various needs. Whenever I raise a support call, Syncfusion support team always come back useful information, and quite often supplies with sample code on how to achieve what I want. Highly recommended.
