Iterate through BindingSource that was created from a DataTable

I have a BindingSource who's DataSource was set to a DataTable that I need to iterate through, how do I go about doing that?

Am I iterating through DataRows of the DataTable? How do I reference those DataRows?

Any help is appreciated!

Foreach (Datarow rw in MyDatatable.Rows)
{
//Do what you need to the row here
messagebox.show(row);
}
