Question

我在WPF应用程序中使用combobox创建了gridview。如图所示，

    <ListView Name="MyListView" Width="261">
        <ListView.View>
            <GridView>

                <GridView.Columns>

                    <GridViewColumn DisplayMemberBinding="{Binding Operation}" />
                    <GridViewColumn>
                        <GridViewColumn.CellTemplate>
                            <DataTemplate>
                                <ComboBox ItemsSource="{Binding Choices}" Width="100px"  />
                            </DataTemplate>
                        </GridViewColumn.CellTemplate>
                    </GridViewColumn>

                </GridView.Columns>

            </GridView>
        </ListView.View>
    </ListView>

而且，我已经在C＃中为gridview中每行的不同数据绑定了组合框，

var dahList = new List<StatsOperation>();
dahList.Add(new StatsOperation
{
    Operation = "Op A",
    Choices = new string[] { "One", "Two", "Three" },
});
dahList.Add(new StatsOperation
{
    Operation = "Op B",
    Choices = new string[] { "4", "5", "6" },
});
this.MyListView.ItemsSource = dahList;

它没有在组合框中显示任何内容
