C# C“WPF：在高度属性设置为”的ListView中，防止水平滚动条覆盖最后一项；“自动”；

我在StackPanel中有一个WPF列表视图，带有Height=“Auto”。它做了我想做的事情，根据ListView中包含的所有项目更改了它的高度，这真是太棒了。我的ListView上还有HorizontalScrollBarVisiblity=“Auto”，这符合我的需要

当我的ListView的列的整个宽度大于ListView控件的宽度（即，用户减小窗口和该控件的宽度）时，就会出现问题。在这种情况下，显然会出现水平滚动条-这没关系。问题是这个滚动条覆盖了ListView项目的最后一个（底部）项目，所以它部分不可见

垂直滚动条没有出现，这是正常的-我不想要它。我只是想让我的ListView高度被正确计算，所以它会考虑显示的水平滚动条的高度，并将其包括在计算中，以便所有项目都是完全可见的

Xaml代码示例：

<ListView Name="lvProcedures" ItemsSource="{Binding Path=Procedures}" SelectionMode="Single">
 <ListView.View>
     <GridView AllowsColumnReorder="False" ColumnHeaderToolTip="Lista zabiegów">
         <GridViewColumn DisplayMemberBinding="{Binding Path=procedure}" Header="A" Width="150" />
         <GridViewColumn DisplayMemberBinding="{Binding Path=location}" Header="B" Width="100" />
         <GridViewColumn DisplayMemberBinding="{Binding Path=material}" Header="C" Width="180" />
         <GridViewColumn DisplayMemberBinding="{Binding Path=other}" Header="D" Width="180" />
         <GridViewColumn DisplayMemberBinding="{Binding Path=description}" Header="E" Width="400" />
     </GridView>
  </ListView.View>
</ListView>

我现在很想创建一个用户控件（可能只是ListView的Derived类？？），它覆盖了MeasureOverride，但我认为这不是解决这么一个小但令人毛骨悚然的“bug”的好方法，而且它仍然让我很难实现解决方案

有人能为这个问题提供一些优雅的解决方案吗？

如果您有任何想法，我们将不胜感激。

@bartivo:我不会得到与您相同的结果-底部的水平滚动条似乎不会模糊最低的项目。我想知道您是否正在为ListView和ScrollViewer使用自定义的ControlTemplate，b/c默认的ScrollViewer模板有两行，第一行是ScrollContentPresenter（Height=“*”），第二行是HorizontalScrollBar（Height=“Auto”），从而确保一行不会与另一行重叠

也许您可以尝试在ListView和ScrollViewer中使用这些样式，看看是否仍然存在此问题：

        <SolidColorBrush x:Key="ListBorder" Color="#828790"/>
    <Style x:Key="{x:Static GridView.GridViewScrollViewerStyleKey}" TargetType="{x:Type ScrollViewer}">
        <Setter Property="Focusable" Value="false"/>
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="{x:Type ScrollViewer}">
                    <Grid SnapsToDevicePixels="true" Background="{TemplateBinding Background}">
                        <Grid.ColumnDefinitions>
                            <ColumnDefinition Width="*"/>
                            <ColumnDefinition Width="Auto"/>
                        </Grid.ColumnDefinitions>
                        <Grid.RowDefinitions>
                            <RowDefinition Height="*"/>
                            <RowDefinition Height="Auto"/>
                        </Grid.RowDefinitions>

通常情况下就是这样。水平滚动查看器将显示在最后一个ListViewItem的下方。只有当ListView的高度因任何原因受到限制时，才会出现您所说的问题，例如，明确设置高度LymeLeak和softwarequestioneer-您完全正确。。。我只是忘记了我使用了我自己的控制风格和模板，呃，在这样简单的问题中浪费了几个小时。我现在已经修复了我的模板，一切都是正确的！谢谢你的回答+1，我会投票，因为巴蒂沃不能：）很高兴你解决了！
