[Mono-winforms-list] DataGridView DataBoundItem return NULL

Hi,

That compiles and runs. When I click on the Show Current thing at the
top, mono dies with the following throwback

System.NullReferenceException: Object reference not set to an instance

Looking at the code, there is a public Cash Selected, but I can't see
where that is instantated from (unless Cash cash = new Cash() does it,
but I can't see how it can.

There isn't a get/set which calls Selected or anything in the form
designer.

TTFN
