Question

我想创建一个窗口，让我可以插入一个公司，其中包含我想要的尽可能多的联系人。表之间的关系我看起来像这样： http://imgur.com/xP2M49k

这是我窗口的XAML（Grid和其他一些不必要的细节被省略）：

        <Label Grid.Row="0" Grid.Column="0" Margin="3 3 3 3">Firmenname</Label>
    <TextBox x:Name="UiCompanyNameTextBox" Grid.Row="0" Grid.Column="1" Margin="3 3 3 3" Text="{Binding Path=CompanyName}"/>

    <Label Grid.Row="0" Grid.Column="3" Margin="3 3 3 3">Branche</Label>
    <ComboBox x:Name="UiBranchComboBox" Grid.Row="0" Grid.Column="4" Margin="3 3 3 3" ItemsSource="{Binding}" DisplayMemberPath="BranchName" 
              SelectedValuePath="id" SelectedValue="{Binding Path=Branch}"/>

    <DataGrid x:Name="UiContactPersonDataGrid" Grid.Row="1" Grid.Column="0" Grid.ColumnSpan="5" CanUserAddRows="True" CanUserDeleteRows="True" 
              Margin="3 3 3 3" ItemsSource="{Binding}" AutoGenerateColumns="False">
        <DataGrid.Columns>
            <DataGridTextColumn Binding="{Binding Path=Company}" Visibility="Collapsed"></DataGridTextColumn>
            <DataGridComboBoxColumn x:Name="UiPersonDataGridComboBoxColumn" Header="Kontaktperson" DisplayMemberPath="Forename" 
                                    SelectedValuePath="id" SelectedValueBinding="{Binding Path=Person}"/>
            <DataGridComboBoxColumn x:Name="UiPositionDataGridComboBoxColumn" Header="Position" DisplayMemberPath="Position" 
                                    SelectedValuePath="id" SelectedValueBinding="{Binding Path=Position}"/>
        </DataGrid.Columns>
    </DataGrid>

这是我的代码背后：

    public partial class AddCompany : Window
        {
            private DataRowView companyDataRowView;
            private ClientManager.ClientManagerDataSet.ContactPersonDataTable contactPersonDataTable;

        public AddCompany()
        {
            InitializeComponent();
        }

        private void Window_Loaded(object sender, RoutedEventArgs e)
        {
            UiBranchComboBox.ItemsSource = DataSetManager.BranchTA.GetData();

            ClientManagerDataSet.CompanyDataTable companyDataTable = DataSetManager.CompanyTA.GetData();
            companyDataRowView = companyDataTable.DefaultView.AddNew();
            UiGrid.DataContext = companyDataRowView;
            companyDataRowView.BeginEdit();

            contactPersonDataTable = new ClientManager.ClientManagerDataSet.ContactPersonDataTable();
            DataView dv = contactPersonDataTable.DefaultView;
            UiContactPersonDataGrid.DataContext = contactPersonDataTable;

            UiPersonDataGridComboBoxColumn.ItemsSource = DataSetManager.PersonTA.GetData();
            UiPositionDataGridComboBoxColumn.ItemsSource = DataSetManager.PositionTA.GetData();
        }

        private void UiApplyButton_Click(object sender, RoutedEventArgs e)
        {
            companyDataRowView.EndEdit();
            DataSetManager.CompanyTA.Update(companyDataRowView.Row);
            DataSetManager.ContactPersonTA.Update(contactPersonDataTable);
            this.Close();
        }
    }

公司的插入工作。但是，我无法绑定Datagrid，以便它插入具有新公司的Company-Id的行。通常我会用一个事务做这个，但是因为使用了DataSet，我认为这必须以某种方式可能吗？

wpf：使用DataSet插入相关行
