FlexSheet for WPF is a fast, lightweight, and powerful control that extends the functionality of C1FlexGrid to provide many Excel-like features. It provides built-in features such as worksheet management, a powerful formula engine, support style format and many more. You can easily import and export spreadsheets, apply formulas, manipulate rows and columns, insert charts and images, perform undo and redo operations, filter columns, format cells and perform cell styling.
C1FlexSheet is a new spin to an old classic, C1FlexGrid. What makes it different from C1FlexGrid is the function support which makes it behave like a spreadsheet.
