High-performance data UI
ProDataGrid
Dense data workflows without compromising interaction or speed.
Overview
A high-performance Avalonia data platform with retained and drawn grid paths, flat and virtual surfaces, source-generated AOT schemas and views, hierarchy, charting, formulas, diagnostics, and production-grade editing.
ProDataGrid treats virtualization, generated schemas, editing, formulas, charting, and diagnostics as one data-workbench problem. Performance cannot erase selection, keyboard flow, validation, automation, or the ability to inspect a live control.
Retained, drawn, flat, hierarchical, and virtual surfaces
AOT-ready generated schemas, columns, operations, and views
Formula engine, charting, selection, editing, and summaries
Performance benchmarks and built-in developer diagnostics
Product architecture
Speed only matters when interaction survives it.
A serious grid is a coordination surface. It must keep a large data set moving while edits, calculations, visual summaries, and debugging tools all observe the same state without fighting for ownership.
From data to decision
- 01 · Viewport
Render what matters
Two-axis virtualization keeps rows and columns bounded while navigation and editing remain stable.
↗ - 02 · Calculation
Recompute with intent
Formula parsing, dependency tracking, and recalculation form an explicit engine rather than cell-side magic.
↗ - 03 · Analysis
Turn values into shape
Charting and pivot-oriented workflows reuse the grid surface instead of exporting users to another tool.
↗ - 04 · Runtime
Inspect the live system
ProDiagnostics exposes trees, properties, and transport seams when a complex control needs evidence.
↗ - 05 · Compile time
Generate the repetitive surface
Typed schemas, columns, operations, views, and AOT fast paths move reflection and boilerplate out of runtime.

In the work
Real output,
not a mockup.
Architecture
Clear layers.
Replaceable seams.
Model
Application state stays in portable domain objects and view models.
Control
Retained, drawn, and virtual surfaces expose focused properties, commands, lifecycle events, automation, and editing.
Generate
Incremental generators produce schemas, columns, accessors, operations, views, and NativeAOT integration at compile time.
Theme
Templates and styles make the surface adaptable to each application.
