c# - DataTables DataRelation Opposite Right Outer Join

Question

3 つの datagridviews (Department、Employee、EmployeeNotInDepartment) があります。DataRelations に基づいて Department と Employee のデータグリッド ビューを作成しました (以下を参照)。EmployeeNotInDepartment データグリッドビューにデータを入力する明らかに簡単な方法が必要だと思います。何か案は？linqを使用する必要がないことを願っています。

public Form1()
{
        InitializeComponent();

        dtDepartment = FillDepartmentList();
        dtEmployee = FillEmployeeList();
        dsDepartmentEmployees = new DataSet();

        // Add tables to dataset
        dsDepartmentEmployees.Tables.Add(dtDepartment);
        dsDepartmentEmployees.Tables.Add(dtEmployee);

        // Create table relationship
        dsDepartmentEmployees.Relations.Add("DepartEmpRelation", dtDepartment.Columns["DepartmentNumber"], dtEmployee.Columns["DepartmentNumber"],true);

        BindingSource bsDepartment = new BindingSource();
        bsDepartment.DataSource = dsDepartmentEmployees;
        bsDepartment.DataMember = "table1";

        BindingSource bsEmployee = new BindingSource();
        bsEmployee.DataSource = bsDepartment;
        bsEmployee.DataMember = "DepartEmpRelation";

        dataGridView1.DataSource = bsDepartment;
        dataGridView2.DataSource = bsEmployee;

}
