I am having trouble generating the RDL report in C# project. If I don't use expressions, the report generates correctly. When I set an expression for the background color:
=IIf(Fields!dzien.Value="Sunday","LightGrey","Transparent")
generating the report ends with an error.
In project I have references
What am I doing wrong? Compilation proceeds without errors.
I have successfully resolved the problem. Microsoft Report Viewer 2015 Runtime was missing from the operating system.
