If I add a new record and then undo I get an Index out of range exception. however if I close the form and do not save changes everything is happy.

Public Property [cucomment]() As System.String

Get

Return CType(Me.CurrentRow.Item("cucomment"), System.String) --> Exception here

End Get

Set(ByVal value As System.String)

Me.CurrentRow.Item("cucomment") = value

End Set

End Property
