Embedding HexViewControl

Use this pattern when you want the control without the repository sample UI.

Recommended Host Structure

Wrap the control in a ScrollViewer
Keep reader, overlay, and formatter lifetime in the host view or view model
Dispose file-backed readers on unload or when opening a new file

Minimal Host State

private MemoryMappedLineReader? _reader;
private ByteOverlay? _overlay;
private ByteOverlayLineReader? _overlayReader;
private HexFormatter? _formatter;

When To Add More Services

Add these only when needed:

SelectionService for fill, zero, increment, randomize, and paste helpers
NavigationService for bookmarks and change navigation
EditJournal for undo and redo
HexSearchService for search and replace

Good Default Settings

ToBase = 16
BytesWidth = 8 or 16
GroupSize = 8
ShowGroupSeparator = true
Encoding = ASCII

Those are also the defaults used throughout the sample surfaces.
