I'm looking for an application developed in C# with following qualities, which is available as source code.
- Based on OO Architecture
- Must connect to DB.
- Must handle atleast a "one to many master child" relationship (eg: Order and items ordered)
- Should display the data using Datagrid or other similar controls.
- Reports (either with report viewer or otherwise)
I want to understand the layering of objects better. Could you please help by providing some links.
