Creating a custom widget with a Forms.BindingSource

I’m building a custom widget for displaying 2 dim data, much like Windows.Forms.DataGridView, and I want to use a Windows.Forms.BindingSource with it. There appears to be plenty of documentation about how to plumb up the data end of the source, and how to set up a single control (such as a TextBox) using a Binding.  What I was more looking for was how the DataGridView reads and writes data directly out of the BindingSource. (As set by the property DataGridView.DataSource).

 Has anyone a pointer to sample code for that?

Thanks
