We just upgraded from Dev Express v2013 vol 2.13 to Dev Express v2014 vol 2.10. During testing with Visual Studio 2012 running in localhost, all of the functionality worked correctly. However, when we published to our testing website (running II7 on a Windows Server 2008 R2 server), we noticed that some of our reporting functionality is broken. When we open a XtraReport in a ReportViewer, the report loads correctly the first time. However, when we use the ReportToolbar to print, navigate pages, or export a report we get the exception "Value does not fall within the expected range."
We are saving the report to a MemoryStream the first time it loads and then restoring it from the stream to keep the user from having to wait on the report creation and data binding again.
Before the upgrade, this worked on the test website. I have attached a sample project showing the basics of what we are doing.
