Good question the line number is offset / bytes in line (ok line numbers 
are stupid for hex editors).
There is a property for the bytes in row in the hexeditordata.

Hi yes it is - there is a line somewhere like:

hexEditor.HexEditorData.Buffer = ArrayBuffer.Load (stream);

change it to :
hexEditor.HexEditorData.Buffer = FileBuffer.Load (stream);

I've not really tested the file buffer but the interface is pretty easy 
to understand. The filebuffer just uses an underlying stream.
