Devolutions.AvaloniaControls.SpreadsheetEditor

An Excel-like spreadsheet editor control for Avalonia UI. It uses a custom grid (not the Avalonia DataGrid) so cells can merge and host rich content, and it ships with:

  • A custom rendering grid with cell merging, frozen headers, and drag-to-select.
  • Rich in-cell editing (bold/italic/underline/strikethrough, fonts, colors, alignment).
  • A hand-rolled = formula engine (arithmetic, ranges, SUM/AVERAGE/IF/…, named ranges, live recalc).
  • Charts, multi-sheet tabs, infinite rows/columns, undo/redo, clipboard, and HTML print.

Requirements

This control depends on the commercial Avalonia Accelerate packages (Avalonia.Controls.RichTextEditor, Avalonia.Controls.Charts). You must supply your own Avalonia UI license key (via the <AvaloniaUILicenseKey> MSBuild item or the standard licensing mechanism) in the application that consumes this control. See https://avaloniaui.net/.

Setup

Add the required theme includes to your App.axaml (alongside FluentTheme):

<Application.Styles>
    <FluentTheme />
    <StyleInclude Source="avares://Avalonia.Controls.RichTextEditor/Themes/Default.axaml" />
    <StyleInclude Source="avares://Avalonia.Controls.Charts/Themes/Default.axaml" />
</Application.Styles>

Usage

xmlns:se="clr-namespace:SpreadsheetEditor.Controls;assembly=SpreadsheetEditor.Controls"
...
<se:SpreadsheetEditor x:Name="Editor" />

The control exposes an integration API similar to Avalonia's RichTextEditor: IsReadOnly, Undo()/Redo() + CanUndo/CanRedo, SelectAll(), SelectedRange, and the ContentChanged, SelectionChanged, and IsReadOnlyChanged events. Load data via LoadSheet, LoadWorkbook, LoadCellData, or LoadRows; read it back with GetCellData/GetRows.
