FlexCelReport.UseLegacyLookup Property
When true, FlexCel will use DataViews to do lookups in DataSets, instead of using its own internal lookup algorithm. Only set this property to true if you have legacy reports that break when you use the internal lookup algorithm, because they depended in bugs in the DataView lookup implementation. For all new code, keep this property false.
