我是c#
WPF 应用程序开发的新手,目前我正在编写第一个应用程序,我能够在一个窗口中显示一个列表,但只能在一个框中显示。
Fitness 框效果很好但我无法获得第二个工作。如果我更改了订单并将WeightList
放在首位,那么它就可以正常工作,并且不会显示ActivityList
。这是代码:
XAML:
<Grid>
<Border BorderBrush="Black" BorderThickness="1" HorizontalAlignment="Left" Height="178" VerticalAlignment="Top" Width="220" Margin="0,3,0,0">

MainWindow.cs
public partial class MainWindow : ModernWindow
{
public static ObservableCollection<Activity> Activities;
public static ObservableCollection<Weight> WeightControl;
public MainWindow()
{
InitializeComponent();
Activities = new ObservableCollection<Activity>() {
new Activity() {Type = "Running", Date = "15.07.2015", Distance = "5km"},
new Activity() {Type = "Cycling", Date = "17.07.2015", Distance = "120km"},
new Activity() {Type = "Swimming", Date = "19.07.2015", Distance = "3km"},
};
ActivityList.ItemsSource = Activities;
WeightControl = new ObservableCollection<Weight>() {
new Weight() {Date = "15.07.2015", currentWeight = 61.2},
new Weight() {Date = "17.07.2015", currentWeight = 62.1},
new Weight() {Date = "19.07.2015", currentWeight = 61.9},
};
答案 0 :(得分:1)
您忘了设置WeightList.ItemsSource。这应该这样做:
static factory method
