Hi,

If you need to show the differences between two revisions of the same document, you could implement a change log and show the differences as a list of log entries recorded between some dates.

An easy way to implement that is to enable the FlowChart.UndoManager and handle the ActionRecorded event. In the event handler, create a log entry based on the command being recorded. Add a time-stamp to each record so you can compare the document revision dates with the log records times.

You can make the collection of log entries serializable and store it in the FlowChart.Tag.

I hope that helps,
Stoyan
