• Visual Studio Subreport, business objects, VB, Local report

  I've been looking at the Orders example (from GotReportViewer.com) and some of the other examples, trying to figure out how to get a subreport to work using business objects.

I have the parameter to tie the main report to the subreport; my key field is text instead of the example's integer but that should be ok. My datasource for the subreport is a List (of ) detail records. Is there any way to find out just ...Show All
