I've been using Syncfusion products for over 5 years now. The grid control is very good and support and supports a large number of cell types that has alway met our needs. The control over user input and cell formatting is extraordinary. Their grid control can also incorporate a treeview aspect that; which saved me from having to source from a separate component supplier; they always seem to be ahead of the curve develompentally. I use their Direct Trak support mechanism infrequently and have never been disappointed in the response; it's alway prompt, effective, and they provided sample code for the solution...it doesn't get any better than that.
