嵌套的滚动条仅部分可见

Question

我无法弄清楚如何为嵌套的ScrollViewer控件提供空间。

我有Border嵌套ScrollViewer，其中包含ListView模板，可以呈现多个DevExpress GridControl控件。

我尝试过添加填充，边距等似乎无法正常工作。

这个网格允许我添加多个StackPanel，因为它们在不同的点可见。我已经删除了简洁的代码。

        <Border BorderThickness="4" Grid.Column="0" Grid.Row="2">
        <ScrollViewer VerticalScrollBarVisibility="Auto" Width="450" MinHeight="200" MaxHeight="600">
            <Grid>
                <StackPanel HorizontalAlignment="Center">
                    <ListView ItemsSource="{Binding FilterItemLists}"  ScrollViewer.HorizontalScrollBarVisibility="Disabled" view:MarginSetter.Margin="5">
                        <ListView.ItemsPanel>
                            <ItemsPanelTemplate>
                                <WrapPanel Orientation="Horizontal"></WrapPanel>
                            </ItemsPanelTemplate>
                        </ListView.ItemsPanel>
                        <ListView.ItemTemplate>
                            <DataTemplate>
                                <StackPanel Orientation="Vertical" Width="200">
                                    <dxlc:LayoutItem VerticalAlignment="Stretch" Padding="4">
                                        <Label Content="{Binding Title}"/>
                                    </dxlc:LayoutItem>
                                    <dxlc:LayoutItem VerticalAlignment="Stretch" Padding="4" Height="200" >
                                        <dxg:GridControl ItemsSource="{Binding Path=Items, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}"

                                            <dxg:GridControl.Columns>
