    /// </summary>
    public partial class MainWindow : Window
    {
        public MainWindow()
        {
            InitializeComponent();
            var data = new List<ComboBoxItem>();
            data.Add(new ComboBoxItem { Name = "7of9" });
            data.Add(new ComboBoxItem { Name = "Janeway" });
            data.Add(new ComboBoxItem { Name = "Tubok" });
            data.Add(new ComboBoxItem { Name = "Chakotay" });
            uxItems.ItemsSource = data;
        }
    }

    public class ComboBoxItem
    {
        public string Name { get; set; }
    }
}

MainWindow.xaml

<Window x:Class="_170612_t1340_comboBox.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

        mc:Ignorable="d"
        Title="MainWindow" Height="350" Width="525">
    <Grid>
        <ComboBox x:Name="uxItems" Height="28" Width="100">
            <ComboBox.ItemTemplate>
                <DataTemplate>
                    <TextBox Text="{Binding Name}"/>
                </DataTemplate>
            </ComboBox.ItemTemplate>
        </ComboBox>
    </Grid>
</Window>

表示に違和感がある。

v0.2

ComboBoxにEnumを列挙する。

を見たところ、DisplayMemberPathを使えば良さそう。

<ComboBox Name="cbSample" DisplayMemberPath="Name"/>

    public class ComboBoxItem
    {
        public string Name { get; set; }
    }
}

違和感がなくなった。
