我有要使用数据绑定在Canvas中显示的项目列表.

ItemsToShowInCanvas = new ObservableCollection<ItemDetail>
   {
       new ItemDetail {Text = "ABC", Top = 10, Left = 200},
       new ItemDetail {Text = "DEF", Top = 100, Left = 300},
       new ItemDetail {Text = "PQR", Top = 50, Left = 150}
   };

ItemDetail是一个简单的类,具有Text,Top和Left值的自动属性

public class ItemDetail
{
    public string Text { get; set; }
    public double Top { get; set; }
    public double Left { get; set; }
}

当我对项目进行数据绑定时,它们会出现在画布中.但是这些项目不会出现在使用"上"和"左"属性提到的位置.

<Canvas>
    <ItemsControl ItemsSource="{Binding Path=ItemsToShowInCanvas}">
        <ItemsControl.ItemTemplate>
            <DataTemplate>
                <TextBlock Text="{Binding Path=Text}" Canvas.Top="{Binding Path=Top}" Canvas.Left="{Binding …

我有进度条，但点太小，如何将其放大？我没有发现任何女巫可以改变点的大小。高度/宽度仅改变点可移动的区域
