如何用静态项填充数据网格中的组合框

我正在开发wpf应用程序，但不使用MVVM架构。我在数据网格中有一个组合框，我静态地填充它的itemssource。这在我的电脑上工作得很好，但是当我在新电脑上安装应用程序时，组合框的itemssource是空的。

CommandeWindow.xaml 

    <DataGrid x:Name="dataGridCommand" ItemsSource="{Binding Path=ProdCommande, ElementName=CommandeWindow,Mode=TwoWay}" AutoGenerateColumns="False" TextOptions.TextFormattingMode="Display" SelectionUnit="FullRow" IsSynchronizedWithCurrentItem="True" IsReadOnly="True" SelectionMode="Single" ColumnWidth="*">            
     <DataGrid.Columns>                                  
      <DataGridTextColumn x:Name="prodReference" CanUserReorder="False" Binding="{Binding refProduit}" Width="150" Header="Référence Paulstra"/>
      <DataGridTextColumn x:Name="prodCDP"  CanUserReorder="False" Binding="{Binding cdp}" Width="50" Header="CDP"/>
      <DataGridTemplateColumn Header="Statut du commande"  CanUserReorder="False" Width="160">
      <DataGridTemplateColumn.CellTemplate>
        <DataTemplate>
            <ComboBox ItemsSource="{Binding StatutCommande, ElementName=CommandeWindow}" SelectedItem="{Binding statut, Mode=TwoWay}"  SelectionChanged="ComboBox_SelectionChanged" >
            </ComboBox>
        </DataTemplate>
       </DataGridTemplateColumn.CellTemplate>
      </DataGridTemplateColumn>
    </DataGrid.Columns>
    </DataGrid>
这是我在 后面的代码

CommandeWindow.xaml.cs 

public object StatutCommande
{
    get { return GetValue(StatutComProperty); }
    set { SetValue(StatutComProperty, value); }
}
// Using a DependencyProperty as the backing store for ACCOU.  This enables animation, styling, binding, etc...
public static readonly DependencyProperty StatutComProperty =
    DependencyProperty.Register("StatutCommande", typeof(object), typeof(Commande), new UIPropertyMetadata(null));

public Commande()
{            
    context = new CRM_HUTCHINSONEntities();
    StatutCommande = new List<string> { "En cours", "Commandée", "Perdue" };
...

如何用静态项填充数据网格中的组合框

我知道怎么解决它了。我只是添加RelativeSource={RelativeSource祖先类型=窗口}到我的itemssource在组合框

<DataGrid x:Name="dataGridCommand" ItemsSource="{Binding Path=ProdCommande, ElementName=CommandeWindow,Mode=TwoWay}" AutoGenerateColumns="False" TextOptions.TextFormattingMode="Display" SelectionUnit="FullRow" IsSynchronizedWithCurrentItem="True" IsReadOnly="True" SelectionMode="Single" ColumnWidth="*">            
     <DataGrid.Columns>                                  
      <DataGridTextColumn x:Name="prodReference" CanUserReorder="False" Binding="{Binding refProduit}" Width="150" Header="Référence Paulstra"/>
      <DataGridTextColumn x:Name="prodCDP"  CanUserReorder="False" Binding="{Binding cdp}" Width="50" Header="CDP"/>
      <DataGridTemplateColumn Header="Statut du commande"  CanUserReorder="False" Width="160">
      <DataGridTemplateColumn.CellTemplate>
        <DataTemplate>
            <ComboBox ItemsSource="{Binding StatutCommande, RelativeSource={RelativeSource AncestorType=Window}}" SelectedItem="{Binding statut, Mode=TwoWay}"  SelectionChanged="ComboBox_SelectionChanged" >
            </ComboBox>
        </DataTemplate>
       </DataGridTemplateColumn.CellTemplate>
      </DataGridTemplateColumn>
    </DataGrid.Columns>
    </DataGrid>
