I have a few classes that I need to present a master detail relationship in
a pair of DataGridViews, i.e.,

class SomeDataList : List<SomeData>

class MyMaster : List<MyDetail> {}
class MyDetail
{
  SomeDataList myData;
}

I have setup the first DataGridView
masterDataGridView.DataSource = myMaster;

And I get the list of MyDetails as expected.

Now, when I click on an instance of MyDetail in the DataGridView, I want to
have the detailDataGridView to show the contents of myData... but I'm not
sure how to setup the DataSource, Binding, etc...

Any ideas?
