Although, I physically select, I get the "System.Data.DataRowView".
When I debug, I saw what you mean by twice.
I want to remember:
I set only these properties of mmCombobox:

Name : cboCustomers
BindingSource : Customer
BindingSourceDisplayMember : CompanyName
BindingSourceValueMember : CustomerID

I try to get CustomerID by selecting CompanyName in combobox.
