C＃WPF将一个ComboBox添加到DataGrid

Question

我在C＃中编写了一个程序，用于在数据库中搜索特定工具，并在DataGrid中显示该工具的规范。我被要求将DataGrid中的一个字段更改为ComboBox。我想我差不多了，但我似乎无法弄清楚如何把它放在我想要的栏目中。任何帮助将不胜感激。

WPF代码`

        <DataGrid.Columns>
            <DataGridComboBoxColumn Header="ComboBox" x:Name="comboboxColumn1"
            SelectedValueBinding="{Binding ComboBox}" />

        </DataGrid.Columns>

    </DataGrid>

`

C＃代码`

public partial class Termination : Window
{

    DataTable Lds;
    SqlDataAdapter adapter;
    SqlConnection connection;

    public List<string> GVComboBox { get; set; }

    public Termination()
    {
        InitializeComponent();
        GVComboBox = new List<string>() { "CRV Owned", "Customer Owned", "CRV Leased", "Customer Leased", "" };
        comboboxColumn1.ItemsSource = GVComboBox;


    }

    private void ApplicatorB_Click(object sender, RoutedEventArgs e)
    {

        Common.sqlApplicator = "Select Terminal,Applicator,applicator_Type as 'Applicator Type',Hand_tool as 'Hand Tool', Hand_Tool_Type as 'Hand Tool Type',Wire_Gauge as 'Wire Gauge',Crimp_Height as 'Core Crimp Height',Conductor_Crimp_Width as 'Core Crimp Width',Insulator_Crimp_Height as 'Insulation Crimp Height',Insulator_Crimp_Width as 'Insulation Crimp Width',Tooling,Notes,Strip_Length as 'Strip Length',Applicator_Status as 'Applicator Status' ,ID from Tooling_Specs where Applicator like '" + ApplicatorTB.Text + "%' order by Applicator";

        try
        { 
            connection.Open();
            adapter = new SqlDataAdapter(Common.sqlApplicator, connection);
            Lds = new DataTable("Applicator");
            adapter.Fill(Lds);
            OutputDG.ItemsSource = Lds.DefaultView;

        }
    catch (Exception E)
            {
            MessageBox.Show(E.ToString());
            }          
    finally
            {
            connection.Close();
    };
        Common.Applicator = ApplicatorTB.Text;
        Common.Terminal = TerminalTB.Text;
        Common.Tool = ToolTB.Text;

        if (Common.admin == false)
        {
            ApplicatorTB.Clear();
        }          
    }`
