- Inherited Members
Remarks
Users can switch from one side to the other by using the tab key.
To enable editing, set ReadOnly to true. When ReadOnly 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.
