Wpf 在DataGrid中绑定CombBox

我不知道如何在代码隐藏中绑定DataGrid中的ComboBox：

我的数据网格：

    <DataGrid x:Name="mydataGridView" HorizontalAlignment="Left" Margin="22,5,0,0" Width="596" ItemsSource="{Binding}"
                  AutoGenerateColumns="False" Height="242" VerticalAlignment="Top">
        <DataGrid.Columns>
            <DataGridTextColumn Binding="{Binding artikel_id}" Header="ArtikelID" Visibility="Hidden"></DataGridTextColumn>
            <DataGridTextColumn Binding="{Binding sifra}" Header="Šifra" Width="60"></DataGridTextColumn>
            <DataGridTextColumn Binding="{Binding naziv}" Header="Naziv" Width="250"></DataGridTextColumn>
            <DataGridTextColumn Binding="{Binding em}" Header="EM" Width="30"></DataGridTextColumn>
            <DataGridTextColumn Binding="{Binding znesek}" Header="Znesek" Width="80"></DataGridTextColumn>
            <DataGridTextColumn Binding="{Binding ddv}" x:Name="DDV" Header="DDV" Width="50"></DataGridTextColumn>
            <DataGridTemplateColumn Header="EM">
                <DataGridTemplateColumn.CellTemplate>
                    <DataTemplate>
                        <ComboBox
                            Name="cmbEM"
                            ItemsSource="{Binding}"
                            Width="60"
                        />
                    </DataTemplate>
                </DataGridTemplateColumn.CellTemplate>
            </DataGridTemplateColumn>
        </DataGrid.Columns>
    </DataGrid>

在datagrid中，我看到除ComboBox为空之外的所有列都已填充。我做错了什么

-->更新

我添加DataGridComboxColumn：

            <DataGridComboBoxColumn x:Name="cmbTest1" Header="EM" DisplayMemberPath="naziv" SelectedValuePath="em"  SelectedValueBinding="{Binding em1}"></DataGridComboBoxColumn>
        </DataGrid.Columns>

而且有效

问候,，

要用什么填充组合框？命名绑定并在该绑定中包含集合。有了DataTable，我想你可以用DataRelation来实现。我找到了一个解决方案，并在更新后发布。无论如何，谢谢你。

            <DataGridComboBoxColumn x:Name="cmbTest1" Header="EM" DisplayMemberPath="naziv" SelectedValuePath="em"  SelectedValueBinding="{Binding em1}"></DataGridComboBoxColumn>
        </DataGrid.Columns>

            cmbTest1.ItemsSource = ds1.Tables[0].DefaultView;
            cmbTest1.DisplayMemberPath = ds1.Tables[0].Columns["naziv"].ToString();
            cmbTest1.SelectedValuePath = ds1.Tables[0].Columns["em"].ToString();
