When handling the BeforeCellRender event it seems that only the BackgroundColor property can be changed.
setting the InnerHtml property does nothing.
After some investigation in de DayPilot source:
the InnerHtml property of the Cell class is used in the CellTable.Process() method but on my machine i never get there...
Is the use of the InnerHtml property supported in the BeforeCellRender event?
