自动高度与最大高度相结合

我在设置以下xaml布局时遇到问题：

RowHeightAuto.xaml

<Window xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    x:Class="GridMaxHeight.RowHeightAuto"
    Title="RowHeightAuto" WindowState="Maximized">
<Grid>
    <Grid.RowDefinitions>
        <RowDefinition />
        <RowDefinition Height="Auto" MaxHeight="200" />
    </Grid.RowDefinitions>
    <StackPanel Background="LightGray" Grid.Row="0"></StackPanel>
    <DataGrid Name="DataGrid1" Grid.Row="1" />
</Grid>

DataGrid1控件没有显示任何定义了大量列和行的滚动条。当我将Height="Auto"替换为Height="*"时，一切都会正常，而不是像预期的那样显示水平和垂直滚动条。

当我直接在DataGrid1中声明MaxHeight时，它也会起作用，但这并不是我真正想要的。

这是子控件在设置Height="Auto"时忽略最大高度的错误吗？还是我可能做错了什么？同样的行为可以用ListBox/ListView等再现，也可以用第三方控件（如ComponentOne、Telerik。。。

如果这是一个bug，你知道变通方法吗？或者有其他提示吗？

以下是我如何设置DataGrid的ItemsSource的代码。RowHeightAuto.xaml.cs

public partial class RowHeightAuto : Window
{
    private readonly DateTime _start;
    public RowHeightAuto()
    {
        InitializeComponent();
        DataGrid1.ItemsSource = GetTestData();
        _start = DateTime.Now;
        Dispatcher.BeginInvoke(new Action(() => MessageBox.Show((DateTime.Now - _start).TotalSeconds.ToString(CultureInfo.InvariantCulture))), DispatcherPriority.ContextIdle, null);
    }
    public static List<TestData> GetTestData()
    {
        const int maxCols = 501;
        const int maxRows = 300;
        var testDatas = new List<TestData>(maxRows);
        for (int i = 0; i < maxRows; i++)
            testDatas.Add(new TestData());
        for (int i = 0; i < maxCols; i++)
        {
            string propName = string.Format("Property{0}", AddLeadingZeros(i));
            for (int j = 0; j < maxRows; j++)
                testDatas[j][propName] = propName;
        }
        return testDatas;
    }
    private static string AddLeadingZeros(int val)
    {
        return val.ToString(CultureInfo.InvariantCulture).PadLeft(3, '0');
    }
}
public class TestData
{
    public object this[string propertyName]
    {
        get
        {
            var myType = GetType();
            var myPropInfo = myType.GetProperty(propertyName);
            return myPropInfo.GetValue(this);
        }
        set
        {
            var myType = GetType();
            var myPropInfo = myType.GetProperty(propertyName);
            myPropInfo.SetValue(this, value, null);
        }
    }
    public string Property000 { get; set; }
    public string Property001 { get; set; }
    public string Property002 { get; set; }
    public string Property003 { get; set; }
    ...
    public string Property498 { get; set; }
    public string Property499 { get; set; }
    public string Property500 { get; set; }
}
