ProDataGrid is a high-performance DataGrid control for Avalonia.

Install the package:

dotnet add package ProDataGrid

Include the theme in App.axaml:

<Application.Styles>
  <FluentTheme />
  <StyleInclude Source="avares://Avalonia.Controls.DataGrid/Themes/Fluent.v2.xaml" />
</Application.Styles>

<Application.Styles>
  <SimpleTheme />
  <StyleInclude Source="avares://Avalonia.Controls.DataGrid/Themes/Simple.v2.xaml" />
</Application.Styles>

Basic XAML usage:

<DataGrid ItemsSource="{Binding People}"
          AutoGenerateColumns="False"
          UseLogicalScrollable="True">
  <DataGrid.Columns>
    <DataGridTextColumn Header="ID" Binding="{Binding Id}" Width="60" />
    <DataGridTextColumn Header="Name" Binding="{Binding Name}" Width="*" />
    <DataGridCheckBoxColumn Header="Active" Binding="{Binding IsActive}" Width="80" />
  </DataGrid.Columns>
</DataGrid>

ProDataGrid ships as a family of packages beyond the grid itself. Quick starts below cover the most common add-ons.

ProCharts is an Excel-quality charting library built for ProDataGrid. ProDataGrid.Charting bridges grid data and pivots into chart series.

Quick start:

dotnet add package ProCharts.Avalonia
dotnet add package ProDataGrid.Charting

using ProCharts;

var chartModel = new ChartModel
{
    Title = "Revenue by Quarter",
    Series = new List<ChartSeries>
    {
        ChartSeries.Line("Q1", new[] { 120d, 140d, 110d, 180d }),
        ChartSeries.Line("Q2", new[] { 160d, 130d, 150d, 210d })
    },
    XAxis = new ChartAxis { Title = "Quarter", Kind = ChartAxisKind.Category },
    YAxis = new ChartAxis { Title = "Revenue", Kind = ChartAxisKind.Value }
};

Bind chartModel to ProChartView.ChartModel in your Avalonia view.

The formula engine provides Excel-compatible parsing, evaluation, and recalculation. Use it in DataGrid formula columns or wire it to your own data model.

Quick start:

dotnet add package ProDataGrid.FormulaEngine
dotnet add package ProDataGrid.FormulaEngine.Excel

var definition = new DataGridFormulaColumnDefinition
{
    Header = "Total",
    Formula = "=[Price] * [Quantity]",
    AllowCellFormulas = true
};

ProDiagnostics provides Avalonia developer tools UI for runtime inspection and debugging, with optional out-of-process transport and a viewer app.

Quick start:

dotnet add package ProDiagnostics

public override void OnFrameworkInitializationCompleted()
{
    if (ApplicationLifetime is IClassicDesktopStyleApplicationLifetime desktop)
        desktop.MainWindow = new MainWindow();

    base.OnFrameworkInitializationCompleted();
    this.AttachDevTools();
}

Optional streaming + viewer:

dotnet add package ProDiagnostics.Transport
dotnet tool install -g prodiagnostics-viewer

Nightly builds are published to GitHub Packages with versions like 11.3.9-nightly.20241227.123.

Add the GitHub Packages feed (requires a GitHub token with read:packages):

dotnet nuget add source https://nuget.pkg.github.com/wieslawsoltes/index.json \
  --name github \
  --username YOUR_GITHUB_USERNAME \
  --password YOUR_GITHUB_TOKEN \
  --store-password-in-clear-text

GitHub Packages NuGet docs: https://docs.github.com/en/packages/working-with-a-github-packages-registry/working-with-the-nuget-registry

Install a nightly package:

dotnet add package ProDataGrid --source github --prerelease

Or pin a specific nightly version:

dotnet add package ProDataGrid --source github --version 11.3.9-nightly.20241227.123

• DocFX articles: docfx/articles/intro.md
• DocFX entry page: docfx/index.md

Run standard tests:

dotnet test

Leak tests use Avalonia-style WeakReference/GC checks. Use the helper script to run only leak tests:

.\tools\run-leak-tests.ps1

ProDiagnostics provides Avalonia developer tools UI as a standalone package. It focuses on runtime inspection and debugging:

• Visual and logical tree inspection.
• Property and style inspection with live values.
• Routed event tracking.
• Layout exploration and renderer diagnostics overlays.

Install from NuGet:

dotnet add package ProDiagnostics

Attach DevTools after application initialization:

public override void OnFrameworkInitializationCompleted()
{
    if (ApplicationLifetime is IClassicDesktopStyleApplicationLifetime desktop)
        desktop.MainWindow = new MainWindow();

    base.OnFrameworkInitializationCompleted();
    this.AttachDevTools();
}

By default DevTools opens with F12. You can also attach to a TopLevel or provide a custom key gesture or options.

ProDiagnostics.Transport streams metrics and activities over UDP so you can observe diagnostics out-of-process.

Install from NuGet:

dotnet add package ProDiagnostics.Transport

Export diagnostics to the viewer:

using ProDiagnostics.Transport;

var exporter = new DiagnosticsUdpExporter(new DiagnosticsUdpOptions
{
    Host = "127.0.0.1",
    Port = TelemetryProtocol.DefaultPort,
    ActivitySourceNames = new[] { "ProDataGrid.*" },
    MeterNames = new[] { "ProDataGrid.Diagnostic.Meter" }
});

exporter.Start();

Keep the exporter alive for the lifetime of the app and dispose it during shutdown.

ProDiagnostics.Viewer is an Avalonia UI for live metrics and activities streamed over UDP.

Install as a global tool:

dotnet tool install -g prodiagnostics-viewer

Run the viewer:

prodiagnostics-viewer
