绑定WPF组合框并将其值显示到TextBox

Question

你好朋友我想显示从DB到组合框的数据,DB表有id,investPlan,金额.现在我想在组合框中显示'investPln'col,当用户选择任何计划时,相应的金额显示在textBox控件中.我能够在comboBox中显示'invetsPlan'行,但不知道如何做休息的事情.帮我!!

XAML部分

<ComboBox Height="23" Margin="70,72,88,0" Name="comboBox1" VerticalAlignment="Top" DropDownClosed="comboBox1_DropDownClosed" 
              ItemsSource="{Binding}" IsSynchronizedWithCurrentItem="True" SelectedValue="{Binding Path=id}" DisplayMemberPath="fullName" SelectedValuePath="id"/>

部分背后的代码

private void Window_Loaded(object sender, RoutedEventArgs e)
    {
        DataSet1TableAdapters.membersTableAdapter ta = new ComboBoxDB.DataSet1TableAdapters.membersTableAdapter();
        comboBox1.ItemsSource = ta.GetData();
    }

<TextBox Text="{Binding ElementName=comboBox1, Path=SelectedItem.amount}" />
