Why Ultimate?

Fast, Flexible, Familiar: Ultimate UI Controls for Visual Studio

GrapeCity’s Ultimate Flex Philosophy comes down to four elements:

Fast Every control is built for maximum performance: our JavaScript, .NET and Xamarin grids and charts are lightning-fast, especially on initial load.

FlexibleExtensibility is built into every control and platform: we build a small core and supply extensions so you can expand only as you need to.

FamiliarOur readable, universal API reduces your learning curve across platforms, and we strive for parity with familiar offerings like Excel.

Small FootprintWe build small and allow you to extend. Wijmo’s FlexGrid has a base size of 113, and our WPF FlexGrid base is less than 250 KB.
