Hi, I'm hopeing someone will be willing to help me with somthing that is probably quite simple.

I'm trying to bind a combobox to a data table, however it is supposed to be a foriegn key field, as such I need the items list to be populated from a different table.

This would be simple if I were doing it at design time, however I am trying to bind at run time. The code I have, simply binds the text to the current record, using the binding source.

I have not been able to get the items list to populate.

private void tbcOPControls_Enter(object sender, EventArgs e)
            if (isManager)
                hasChanged = false;
                dbDataSetXSD dsTheData = new dbDataSetXSD();
                //instantiate the table adapter for the staff table
                dbDataSetXSDTableAdapters.tblStaffTableAdapter dsTblStaff = new Cinemax.dbDataSetXSDTableAdapters.tblStaffTableAdapter();
                //Create a binding source
                bsTblStaff = new BindingSource();
                //Attatch the binding source to the table adapter
                bsTblStaff.DataSource = dsTheData.tblStaff;
                //Fill the table adapter
                //Create data bindings
                txtStaffID.DataBindings.Add(new Binding("Text", bsTblStaff, "StaffID"));
                cmbStaffTitle.DataBindings.Add(new Binding("Text", bsTblStaff, "Title"));

                txtStaffSurname.DataBindings.Add(new Binding("Text", bsTblStaff, "Surname"));
                txtStaffFirstName.DataBindings.Add(new Binding("Text", bsTblStaff, "FirstName"));
                txtStaffAddress.DataBindings.Add(new Binding("Text", bsTblStaff, "AddressLine1"));
                txtStaffTown.DataBindings.Add(new Binding("Text", bsTblStaff, "Town"));
                txtStaffCounty.DataBindings.Add(new Binding("Text", bsTblStaff, "County"));
                txtStaffPostCode.DataBindings.Add(new Binding("Text", bsTblStaff, "Postcode"));
                txtStaffRole.DataBindings.Add(new Binding("Text", bsTblStaff, "StaffRole"));
                cmbStaffBoss.DataBindings.Add(new Binding("Text", bsTblStaff, "BossID"));
                cmbStaffBoss.DataSource = dsTheData;
                cmbStaffBoss.DisplayMember = dsTheData.tblCinema.ManagerIDColumn.ToString();
                cmbStaffCinema.DataBindings.Add(new Binding("Text", bsTblStaff, "CinemaID"));
                txtStaffUserID.DataBindings.Add(new Binding("Text", bsTblStaff, "UserID"));
                txtStaffPassword.DataBindings.Add(new Binding("Text", bsTblStaff, "Password"));

                btnPrevious.Visible = true;
                btnNext.Visible = true;

the binding works fine for passing throw the records, is just the combo boxes that are a problem. Please can anyone help?

Thanks for taking the time to read.
