即使内容比容器高，WPF控件也会对齐到底部

Question

我有一个需要显示的控件，以便即使该控件比其容器高，它也始终在其容器的底部对齐。 我已经设置了控件的VerticalAlignment="Bottom" ，当容器更大时，它可以正常工作，但是当容器缩小时，控件的顶部与容器的顶部对齐，并且底部被切除。 我需要切断顶部。

<Window x:Class="NestedListBox.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:system="clr-namespace:System;assembly=mscorlib"
        x:Name="Root"
        Title="MainWindow" Height="185" Width="525">
    <Grid>
        <ItemsControl VerticalAlignment="Bottom">
            <system:String>Test 1</system:String>
            <system:String>Test 2</system:String>
            <system:String>Test 3</system:String>
            <system:String>Test 4</system:String>
            <system:String>Test 5</system:String>
            <system:String>Test 6</system:String>
            <system:String>Test 7</system:String>
            <system:String>Test 8</system:String>
            <system:String>Test 9</system:String>
            <system:String>Test 10</system:String>
            <system:String>Test 1</system:String>
            <system:String>Test 2</system:String>
            <system:String>Test 3</system:String>
            <system:String>Test 4</system:String>
            <system:String>Test 5</system:String>
            <system:String>Test 6</system:String>
            <system:String>Test 7</system:String>
            <system:String>Test 8</system:String>
            <system:String>Test 9</system:String>
            <system:String>Test 10</system:String>
        </ItemsControl>
    </Grid>
</Window>

当您拖动窗口大于ItemsControl ，它将保持与底部对齐，但是一旦窗口变小，顶部就会对齐。

除了Grid ，我还尝试了DockPanel将ItemsControl设置为具有DockPanel.Dock="Bottom" ，但这也不起作用。

您可以使用Canvas达到预期效果

请注意，将从ItemsControl和Canvas.Bottom删除了VerticalAlignment设置为0以使其固定在Canvas的底部。

<Grid>
    <Canvas>
        <ItemsControl Canvas.Bottom="0">
            <system:String>Test 1</system:String>
            <system:String>Test 2</system:String>
            <system:String>Test 3</system:String>
            <system:String>Test 4</system:String>
            <system:String>Test 5</system:String>
            <system:String>Test 6</system:String>
            <system:String>Test 7</system:String>
            <system:String>Test 8</system:String>
            <system:String>Test 9</system:String>
            <system:String>Test 10</system:String>
            <system:String>Test 1</system:String>
            <system:String>Test 2</system:String>
            <system:String>Test 3</system:String>
            <system:String>Test 4</system:String>
            <system:String>Test 5</system:String>
            <system:String>Test 6</system:String>
            <system:String>Test 7</system:String>
            <system:String>Test 8</system:String>
            <system:String>Test 9</system:String>
            <system:String>Test 10</system:String>
        </ItemsControl>
    </Canvas>
</Grid>
