I just upgraded from ActiveReports 11 to ActiveReports 18 via the automatic upgrade tool. I had to make some minor adjustments, but everything seems to be working OK except for two issues…
-
A single page SectionReport that used to be 5K when exporting to PDF is now 50K+.
-
I WAS getting “random” NullReferenceExceptions in ActiveReports designer code that is calling SetStylesheet() internally which then calls System.ComponentModel.TypeDescript.GetPropertiesImpl. I was able to solve this in the designer.cs by having the StyleSheet.Add() lines before the Sections.Add() lines. If this in fact is required, the ActiveReports upgrade wizard should move that data accordingly.
