I have a datagrid control on a Vb.net form(datagrid1 on form1).
now i have 2 questions about datagrid1 (assuming the datagrid has only 2
columns)
1) create a new empty row in a datagrid from code

I have a custom control which contains a 'public List<ListItem> { get; }'
property. The developer can update this property at design-time using the
usual CollectionEditor mechanism. Unfortunately my code requires a call to a
Rebuild() method before the changes are made visible ...
