Combobox及其项目显示问题wpf

Question

我使用以下代码显示组合框中的项目。但是项目没有显示出来。

代码：

<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"; 

Answer 1

确保您绑定的属性定义了“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; }
}

另外，看看你的'输出'窗口，确定你是否有任何绑定错误。

希望这有帮助！

您是否在组合框上尝试过DisplayMemberPath属性？
