问题
i have the following situation, i have a Reporting layer(stand alone) in asp.net application(NOT website, this means NO App_Code folder exists), and i want just to create Object Data Source to take an Object in a separate layer(lets say from Data Access Layer), and then to use that Object Data Source to create a report, i have spent my whole day working around that, tons of work around's and articles on the web, but does not mention what i really want to do, any answer is appriciated...
just to make things more clear here, assume the following:
i have a solution with the follwoing layers,
- UI
- Reporting(has NO Employees object) just a reference
- Business Logic
- Data Access Layer(Employees-->GetEmployees(),
all i need is as mentioned above, i want to create Object Data Source from Reporting layer, to take Employee object from DAL, and then use it's GetEmployees method to be added to report, i think its more clear now, since also Reporting layer has NO App_Code folder.

The way Ive been doing it is by creating a class that has a property of type List. I dhave a method called LoadReport(params......) in this class where I would call GetEmployess to populate my property.
I would then add a new Dataset in the report designer, selecting to bind to Object, and selecting the class i created. Once finished the dataset will allow you to expand the List property where you can drag different fields onto the designer.
Ive done this in VS2008, currently attempting in VS2010
