Hello,
it would be nice to get access to the LineBreak property of the StringList, you are using in
TAdvStringGrid.OutputRectToCSV.
For a special export format I 've to add another colum delimiter and that is currently impossible to do with then standard export.
Another option would be an event to change a line before it got written in the file. There are plenty events in TAdvStringGrid but not any for exports or imports.
