在使用WaterfallPanel时出现异常

[BFNOC]

异常内容：

System.InvalidOperationException:“元素“HandyControl.Controls.WaterfallPanel”的布局测量覆盖不应将 PositiveInfinity 作为其 DesiredSize 返回，即使将 Infinity 作为可用大小传入。”

我是在ItemsControl里面使用WaterfallPanel的

<ItemsControl ItemsSource="{Binding Value}">
  <ItemsControl.ItemsPanel>
      <ItemsPanelTemplate>
          <hc:WaterfallPanel Groups="8"/>
      </ItemsPanelTemplate>
  </ItemsControl.ItemsPanel>

这个问题我在网上搜过几遍，没有找到解决办法，有大佬可以解决吗？

Hi 🖐,
I just test the WaterfallPanel into a ItemsPanelTemplate and it's working perfectly for me. Maybe your exception is coming from your ItemsSource Bind : Value

Here my code :

MainWindow.xaml.cs

public partial class MainWindow : Window
    {
        public List<string> MyList { get; set; }

        public MainWindow()
        {
            InitializeComponent();
            DataContext = this;
            MyList = new List<string>() {"Test","Test", "Test", "Test", "Test", "Test", "Test", };
        }
}

MainWindow.xaml

        <ItemsControl ItemsSource="{Binding MyList}">
            <ItemsControl.ItemsPanel>
                <ItemsPanelTemplate>
                    <hc:WaterfallPanel Groups="8"/>
                </ItemsPanelTemplate>
            </ItemsControl.ItemsPanel>
        </ItemsControl>

Result :
