The world's first WinForms spreadsheet component to draw with Direct2D on the GPU (our research, as of October 2026). Scrolling repaints are about 3.5× faster than GDI+, WPF frames about 7× faster and Avalonia up to 8×.
Direct PDF export, a rich-text cell editor, printed headers and footers, fit-to-page printing, and XLSX page setup that round-trips.
A rebuilt, fully virtualized core, faster and lighter in both WinForms and WPF, plus support for Avalonia. One version-independent license now covers V4 and V5.
47 Excel-compatible formula functions, point-mode formula editing, XLSX outline import/export, and major load performance & memory improvements.
Significantly faster processing for large datasets, with full API compatibility maintained.
An Excel-like spreadsheet component for web apps.
