Seriously, I never really delved into the "how", other than "how to make it work". If you're using a DataTable (or a BindingSource), they automatically work with databinding. Check this link, "Data Sources Supported By Windows Forms":
http://msdn.microsoft.com/en-us/library/f3y6cb0c.aspx. Here's an excerpt:
In Windows Forms, you can bind to a wide variety of structures, from simple objects (simple binding) to complex lists such as ADO.NET data tables (complex binding). For simple binding, Windows Forms supports binding to the public properties on the simple object. Windows Forms list-based binding generally requires that the object support the IList interface or the IListSource interface. Additionally, if you are binding with through a BindingSource component, you can bind to an object that supports the IEnumerable interface. For more information about interfaces related to data binding, see Interfaces Related to Data Binding.~~Bonnie

>>First, what kind of list are you talking about specifically? A ListView or a ListBox control? (Or a List< >? ... which isn't a control.)

>>Secondly, I wouldn't databind to a DataRow ... you want to bind to the DataTable or to a BindingSource (which the developer could set to anything, which may be good or bad, depending on whether you do or do not want to limit what's allowed with your class). I wrote my Framework back in the 1.1 days, and BindingSource was not introduced until 2.0, consequently all of my controls databind to a DataTable.
