Setting a new DataGridViewComboBoxCell value

[Martin Marvinski]

I'm populating a DataGridView control using the Add Row method and an object array as the basis for that new row. All the cells work fine except the DataGridViewComboBoxCell which gives me an exception titled "ArgumentException: DataGridViewComboBoxCell value is not valid". How do I resolve this problem? thank you, Martin :rose::):):)
