WinForms: Best Practices for Using an Object Data Source

Question

I want to bind a list of business objects to a Winforms control (DataGridview, ComboBox, etc).

There are several ways to do this:

I can create wrapper classes for business objects and override their method implementation ToString. This will work well for ComboBox, ListBox methods Items.(Add|AddRange).

But this will not work for a DataGridView. It requires that an ObjectDataSource object configure columns in design mode.

As it should be ObjectDataSources (for DataGridViews) and wrapper classes, I decided to leave only one approach. ObjectDataSource

Now I have ObjectDataSources for data binding. When I use the wizard, it adds a property to the form, which I can use as follows:

MyObjectDataSoure.DataSource = list-of-entities;

This fills the base winforms control. But I can also assign a list of objects directly to the control data source and population properties. Same.

 MyWinformsControl.DataSource = list-of-entities

Yes, now I am without ObjectDataSource events, but maybe there is something more general that I missed? Should I avoid listening to winforms events (the selection is changed, the user adds a row) and uses the object data of the data source?

What are the best practices for using object data sources and events?

Thank you in advance!
