I am using VB .NET to view crystal reports in the crystal report viewer activeX control, and I am using the CrystalDecisions.CrystalReports.Engine.ReportDocument class to load reports dynamically at runtime and add conditions and sorting options at runtime too. I use the record selection formula to add conditions at runtime. The problem is that I want to ADD sorting options (fields and sort direction) at runtime, but I can't. Can anyone help please? Thank you in advance.
