我使用以下代码来显示组合框中的项目。但项目未显示。

<ComboBox Width="100" ItemsSource="{Binding}" SelectedIndex="0" Name="cbProduct"/>
  List<ComboObject> combObjList = new List<ComboObject>();

        combObjList.Add(new ComboObject { Text = "All", Value = "%" });
        combObjList.Add(new ComboObject { Text = "Music", Value = "1" });
        combObjList.Add(new ComboObject { Text = "Games", Value = "2" });
        combObjList.Add(new ComboObject { Text = "Video", Value = "3" });

        cbProduct.DataContext= combObjList;
        cbProduct.DisplayMemberPath = "Text";
        cbProduct.SelectedValuePath = "Value";

确保要绑定的属性定义了“get”。

public ObservableCollection<ComboObject> CombObjList
    {
        get { return combObjList; }
    }
    private ObservableCollection<ComboObject> combObjList = new ObservableCollection<ComboObject>();

class ComboObject
{
    public string Text { get; set; }
    public string Value { get; set; }
}

希望这有帮助!

你试过在组合框上显示memberpath属性吗?
