I am looking for a high-performance grid in my .Net winform application, my current solution is too slow, API is to complex and don't meet my requirements. I would appreciate some help. Thanks

what kind of Grid are making use of currently? you can consider using virtual mode with the standard data Grid View. however , your best bet will be Dapfor's .Net Grid because of the high performance and simple API. there are several other features that you will find useful like databinding etc
