Hi Matt,

I assume you are using a DataSet by choice as opposed to using an EntityList.

With a datagrid there is a BindingSourceType property that would need to be set to "Data" for DataSets. I don't see that with a comboBox. I wonder if you need to be setting the DataSource and DisplayMember rather than the BindingSource and BindingSourceDisplayMember properties.

All that said, if you do away with the dataset and just bind directly to the Business Object you won't have this issue.
