Canvas Data Grid

DOM-rendered Blazor grids slow down as rows and features stack up, and the commercial alternatives (AG Grid, Syncfusion, Telerik) are licensed dependencies you don't control. Most teams accept the licence cost because building a serious grid is considered too expensive.

A high-performance Blazor data grid that paints cells to a canvas and overlays real DOM inputs only where typing happens — with multi-column sort, a per-column filter row, pivot aggregations, pinning, formula columns and CSV export.

Rendering model

hybrid — canvas cells, DOM-overlay filter inputs

Sorting

multi-column with chained ThenBy and order badges

Pivot aggregations

sum / avg / min / max / count per column

Formula columns

spreadsheet-style computed cells (=SUM, cross-column expressions)

State persistence

column order, widths, pinning, visibility, sort and pivot to localStorage

Hardening

8 audit-driven correctness and security fixes shipped (LINQ allowlist, cancellation, JS teardown)
