WPF：Stretch treeview

Question

我是WPF的新手，我需要一种方法将树视图控件拉伸到完整的可用尺寸..因此，水平和垂直拉伸是我的第一个猜测，但树视图的行为类似于“自动”大小...

我正在做某事。这里错了吗？

    <Grid.RowDefinitions>
        <RowDefinition Height="*"></RowDefinition>
        <RowDefinition Height="Auto"></RowDefinition>
    </Grid.RowDefinitions>  
    <Grid.ColumnDefinitions>
        <ColumnDefinition Width="*"></ColumnDefinition>
    </Grid.ColumnDefinitions>
    <StackPanel Grid.Row="0" Orientation="Vertical">
        <TreeView VerticalAlignment="Stretch" HorizontalAlignment="Stretch">
            <TreeViewItem>asdasd</TreeViewItem>
            <TreeViewItem>asdasd</TreeViewItem>
        </TreeView>
    </StackPanel>
    <Label Grid.Row="1">asdasd</Label>
</Grid>
</Window>

您已将树包裹在StackPanel中。删除StackPanel，你可能会得到你想要的东西。
