问题描述

I have an MVVM application and would like to add Crystal Reports. I have a ViewModel of PatientList and would Like to Bind the Report to an Observable collection of Patients in the ViewModel. the Collection is not appearing in the data sources window.

推荐答案

我猜您是在引用Crystal-Reports数据源窗口，对吗? 如果是这样-我想您永远不会在那儿找到ObservableCollection(而且我不知道您是否可以让CR观察该集合)，但是在Crystal-Report的文档类上，您应该有类似SetDatasource的内容(我不会不再有最新版本，CR会不时更改此版本)-在最新版本中，我知道您在某些情况下(DataTable)必须转换为IEnumerable<...>，所以也要注意这一点.

I guess you are refering to Crystal-Reports datasource window right? If so - I think you will never find the ObservableCollection there (and I don't know if you can have CR observe the collection) but on the document-class in Crystal-Report you should have something like SetDatasource (I don't have the newest version anymore and CR changed this from time to time) - in the last version I know you had to cast to IEnumerable<...> in some cases (DataTable) so look out for this too.
