WPFHexaEditor 3.0.5

WPFHexaEditor

A full-featured WPF hex editor UserControl for .NET 8. Successor to WPFHexaEditor.

Quick Start

<Window xmlns:hexe="clr-namespace:WpfHexEditor.HexEditor;assembly=WpfHexEditor.HexEditor">
    <hexe:HexEditor FileName="C:\path\to\file.bin" />
</Window>

dotnet add package WPFHexaEditor

What's New in 3.0.5

• Fix: BCB (Custom Background Block) visual tree locked during navigation to prevent mouse re-dispatch loop
• Fix: Bookmark chip MouseDown re-dispatch loop eliminated
• Fix: Bookmark chips no longer re-render on every navigation — repaint only on actual changes

What's New in 3.0.4

• Fix: ResourceReferenceKeyNotFoundException no longer thrown in standalone WPF apps — GetThemeColor now uses TryFindResource instead of FindResource (fixes #228)
• Fix: Drag-selection auto-scroll — cross-panel mouse boundary no longer stops scrolling in HexEditor (fixes #227)
• Fix: Column/row highlight tracks cursor position correctly on vertical scroll
• Feat: Context menu — drop shadow, MDL2 icons, accent band, light theme styling

What's New in 3.0.3

• Fix: AllowCustomBackgroundBlock dependency property is now obsolete and has no effect. Custom background blocks render automatically when blocks are added via AddCustomBackgroundBlock(). Use AddCustomBackgroundBlock() / ClearCustomBackgroundBlock() as the sole control point.
• Localization: 18 satellite assemblies now bundled in the package (ar-SA, de-DE, es-ES, fr-FR, ja-JP, zh-CN, and 12 more). No separate install required.

What's New in 3.0.2

• Column ruler support
• Scroll marker panel improvements
• Format detection performance improvements

What's New in 3.0.0 (since WPFHexaEditor 2.1.7)

Breaking Changes

• Target framework: .NET 8.0-windows (dropped .NET Framework 4.7 and .NET Core 3.1)
• Namespace renamed: WPFHexaEditor → WpfHexEditor.HexEditor
• Assembly renamed: WPFHexaEditor.dll → WpfHexEditor.HexEditor.dll
• Modular architecture: core logic extracted into separate assemblies (Core, BinaryAnalysis, Definitions, Editor.Core)

Performance

• GlyphRun-based text renderer — replaces FormattedText, eliminates per-glyph allocation
• LineVisualPool — object pooling for visible line elements, zero GC pressure on scroll
• HexLookup table — O(1) byte-to-hex conversion via precomputed 256-entry table
• TBL key buffer — zero-allocation custom table encoding
• DrawingContext renderers for HexBox and ProgressBar controls
• Cached DPI, FormattedText, and Pens — 25-55ms → 5-8ms render time in docking scenarios
• Dirty-line tracking — only re-render lines that changed, not the full viewport
• Mouse hover overlay — eliminated full re-render on mouse move

New Features

• 400+ built-in format definitions (.whfmt) — automatic format detection and syntax coloring for PE, ELF, ZIP, PNG, PDF, MP3, SQLite, and hundreds more
• Column and row highlighting — visual cursor tracking across hex and ASCII panels
• Undo/redo overhaul — UndoGroup composite, transactions, coalescence, history dropdown
• Binary analysis — Shannon entropy, byte distribution, anomaly detection, data type estimation
• Intel HEX / S-Record — import/export support
• Binary template compiler — 010 Editor compatible C-like templates
• Format field overlay — semi-transparent colored blocks over detected format structures
• Settings UI — dynamic property editor with ColorPicker for all editor properties
• IDocumentEditor interface — standardized editor contract for hosting frameworks

Bug Fixes

• Row highlight now updates on vertical scroll
• Null guard on UpdateColumnHighlight
• FileSystemWatcher re-fire suppressed during ReloadFromDisk
• ByteToolTipDisplayMode/DetailLevel DP defaults synced to HexViewport at init
• MouseWheelSpeed DP implemented in scroll handler

Included Assemblies

All bundled inside the package — zero external NuGet dependencies:

Localizations: ar-SA, de-DE, es-419, es-ES, fr-CA, fr-FR, hi-IN, it-IT, ja-JP, ko-KR, nl-NL, pl-PL, pt-BR, pt-PT, ru-RU, sv-SE, tr-TR, zh-CN
