MS ReportViewer LocalMode: Report item not linked to a dataset.
-
We have a set (~50) of local mode reports hosted in forms as plugins (dlls) in our app. They were initially developed in VS2005 and later ported to VS2008. We are now attempting to get them working in VS2010. The reports use lists to iterate over a table, invoking a subreport with the ID (primary key) as a variable/parameter so that the subreport could select details from related tables and display them. Some of the subreports used lists and sub-subreports, on and on. However, as of VS2010, even once we get the reports building and running they don't work properly. When we attempt to assign parameters to a subreport in the parent reports' design[er] using Right-click -> Subreport Properties -> Parameters -> Fields Then either... Add to create a new one or f[unction] to edit one that's broken... We get "Report item not linked to a dataset." This happens even if the Field (name) appears in the "Value" combobox and we select it. Does anyone know how to fix this or get past it...
