Hiding DataGridView Row 0 produces error

Question

In my DataGridView, it fails to hide a row, if that row is index 0.

row associated with the currency manager's position cannot be made invisible

Dim cm1 As CurrencyManager = CType(BindingContext(dgv.DataSource), CurrencyManager)
cm1.SuspendBinding()
dgv.Rows.Item(0).Visible = False 'this throws the exception

I could pretty easily put a try/catch inside the for loop, but thats just ignoring the problem :-P — adam, Nov 12 '14 at 13:54

From my understanding I believe if that's the only row left and it's selected the row or cell must be visible. To get around this you could possibly setting the current cell to null then SuspendBinding...

Here's a simple example...

 Me.dgv.CurrentCell = Nothing
 Me.cm1.SuspendBinding()
 Me.dgv.Rows(index).Visible = False
