当我在ListView.ItemsPanel中设置WrapPanel时,右滚动条会丢失(不可见)。并且内容通过鼠标滚轮滚动,当然,通过研究此滚动查看器中的可视树,所有属性都已正确安装。这里可能有什么问题以及为什么他不可见。

        <Style TargetType="{x:Type ListView}">
            <Setter Property="ItemsPanel">
                <Setter.Value>
                    <ItemsPanelTemplate>
                        <WrapPanel Background="Transparent" MouseDown="WrapPanel_MouseDown_1" 
                             IsItemsHost="True"
                             Width="{Binding Path=ActualWidth,  RelativeSource={RelativeSource Mode=FindAncestor, AncestorType={x:Type ScrollContentPresenter}}}">

                        </WrapPanel>
                    </ItemsPanelTemplate>
                </Setter.Value>
            </Setter>
            <Setter Property="ItemTemplate">
                <Setter.Value>
                    <DataTemplate>
                        <Grid>
                            <Grid.ColumnDefinitions>
                                <ColumnDefinition Width="Auto" />
                                <ColumnDefinition />
                            </Grid.ColumnDefinitions>
                            <Path Fill="{Binding ElementName=tBlock, Path=Foreground}" Width="20" Height="20" Margin="5, 0, 0, 0" Stretch="Uniform" Data="{Binding SmallIcon}" />
                            <TextBlock Margin="5, 4, 5, 0" x:Name="tBlock" Grid.Column="1" TextWrapping="Wrap" Width="200" Text="{Binding Name}"></TextBlock>
                        </Grid>
                    </DataTemplate>
                </Setter.Value>
            </Setter>
        </Style>

VerticalScrollBarVisibility和/或HorizontalScrollBarVisibility设置为所需的值:

<ListView
          ScrollViewer.HorizontalScrollBarVisibility="Visible" 
          ScrollViewer.VerticalScrollBarVisibility="Visible"> 
    <ListView.Style>
        <Style TargetType="{x:Type ListView}">
         // ...
默认情况下,

VerticalScrollBarVisibilityAuto,我无法复制您的问题。但是,我希望这会有所帮助。
