public class HexView : View, IDisposable, ISupportInitializeNotification, ISupportInitialize, IDesignable- Inheritance

HexView
- Implements
- Inherited Members
Remarks
HexView provides a hex editor on top of a seekable Stream with the left side showing the hex values of the bytes in the Stream and the right side showing the contents (filtered to non-control sequence ASCII characters).
Users can switch from one side to the other by using the tab key.
To enable editing, set AllowEdits to true. When AllowEdits is true the user can make changes to the hexadecimal values of the Stream. Any changes are tracked in the Edits property (a SortedDictionary<TKey, TValue>) indicating the position where the changes were made and the new values. A convenience method, ApplyEdits(Stream?) will apply the edits to the Stream.
Control the byte at the caret for editing by setting the Address property to an offset in the stream.
Control the first byte shown by setting the DisplayStart property to an offset in the stream.

- BytesPerLine
The bytes length per line.
- DisplayStart
Sets or gets the offset into the Stream that will be displayed at the top of the HexView.
- Edits
Gets a SortedDictionary<TKey, TValue> describing the edits done to the HexView. Each Key indicates an offset where an edit was made and the Value is the changed byte.
- Position
