I solved this problem awhile ago. It seems that there is only one way to attach your data source for the combo box to work correctly.
cboPhoneNumberTypes.DataSource = ds.Tables[“tblPhoneNumberTypes_ManageContact”];
cboPhoneNumberTypes.DisplayMember = “PhoneNumberType”;
cboPhoneNumberTypes.ValueMember = “PhoneNumberTypeId”;
I could only get it to work by assign the datasource via the table collection of a data set.
Hope this helps,
