C# WPF bir datagrid combobox sütununu SQL Server 2014'ten doldurma

Question

Bu DataGrid'i dolduracak bir C# programı yazıyorum. Ayrıca bir combobox'ım olan sütunu doldurmayı da çok isterim. Kombobox'ın doğru bir şekilde çalıştığı bir seçim listesi var. Bu sütunu veritabanından veri ile dolduramıyorum. Sanırım gerçekten yakınım, neyi kaçırdığımı anlayamıyorum.

Şimdiye kadar geldiğim XAML.

<Window x:Class="datagridcombobox.MainWindow" 
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" 
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" 
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008" 
    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" 
    xmlns:local="clr-namespace:datagridcombobox" 
    mc:Ignorable="d" 
    Title="MainWindow" Height="350" Width="525" Loaded="Window_Loaded"> 

    <Grid> 
     <Grid.ColumnDefinitions> 
      <ColumnDefinition/> 
      <ColumnDefinition Width="0*"/> 
     </Grid.ColumnDefinitions> 

     <DataGrid AlternatingRowBackground="#FFC4B0B0" Height="200" Width="500" AutoGenerateColumns="False" Name="grdEmployee" Margin="2,0,1,-81"> 
      <DataGrid.Columns> 
       <DataGridComboBoxColumn Header="Terminal" x:Name="comboboxColumn1" SelectedValueBinding="{Binding Terminal}"/> 
       <DataGridTextColumn Binding="{Binding Terminal}" Width="100" Header="Terminal"/> 
       <DataGridTextColumn Binding="{Binding Applicator}" Width="100" Header="Applicator"/> 
       <DataGridTextColumn Binding="{Binding applicator_Type}" Width="100" Header="Applicator Type"/> 
       <DataGridTextColumn Binding="{Binding Hand_tool}" Width="100" Header="Hand Tool"/> 
       <DataGridTextColumn Binding="{Binding Hand_Tool_Type}" Width="100" Header="Hand Tool Type"/> 
       <DataGridTextColumn Binding="{Binding Wire_Gauge}" Width="100" Header="Wire Gauge"/> 
      </DataGrid.Columns> 
     </DataGrid> 
    </Grid> 
</Window>

    public MainWindow()

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

     } 
     catch (Exception E) 
     { 
      MessageBox.Show(E.ToString()); 
     } 
     finally 
     { 
      connection.Close(); 
     }; 

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

    private void Window_Loaded(object sender, RoutedEventArgs e) 
    { 
     connection = new SqlConnection(Common.ConnectionString); 
     Step1(); 
    } 
}

SqlCommand cmd = new SqlCommand("SELECT * FROM YourDataBase", yourConnectionName); 
SqlDataReader read = null; 
read = cmd.ExecuteReader(); 
while(read.Read()) 
{ 
    YourComboBox.Items.Add(read["YourValue"].ToString() + "read["value1"].ToString()+ "StringValue"); 
} 
read.Close();
