DataGridView: Index -1 does not have a value

Hi,

I'm using the DataGridView in VB.NET 2.0. The DataSource is a Generic List
of a custom class0: lstMyPersonnes = New List(Of clsPersonne).

When I add a new clsPersonne to lstMyPersonnes, and rebind the
lstMyPersonnes to my DataGridView.dataSource, it shows the new record in
the DataGridView as it should be.

But when I click on a cell of that row, I suddenly got this error: "Index -1
does not have a value"...

Does anybody has any idea how to get around this problem?

Thanks a lot in advance,

Pieter

PS: I'm using the RC of Visual Team Suite.

The whole exception:

System.IndexOutOfRangeException was unhandled
Message="Index -1 does not have a value."
