I got this XAML for my ListView:

<Grid x:Name="gSearch"  Grid.Row="1" Margin="0,45,871,0" >
                        <ListView x:Name="lVsearch" Height="472" Margin="15,7,5,17" SelectionMode="Single" 
                                      
                                      HorizontalContentAlignment="Stretch" ScrollViewer.CanContentScroll="True" >
                            <ListView.Template>
                                <ControlTemplate>
                                    <Border CornerRadius="3" BorderThickness="1" BorderBrush="LightGray" Background="{TemplateBinding Background}">

                                </DataTemplate>
                            </ListView.ItemTemplate>
                        </ListView>
                    </Grid>

i不知道为什么ListView没有显示ScrollBars？



我尝试过：



ScrollViewer.CanContentScroll = true

i don't know why the ListView is not showing the ScrollBars?

What I have tried:

ScrollViewer.CanContentScroll = true

推荐答案

您的控制模板中需要 ScrollViewer ：

You need a ScrollViewer in your control template:

<ListView.Template>
    <ControlTemplate>
        <Border CornerRadius="3" BorderThickness="1" BorderBrush="LightGray" Background="{TemplateBinding Background}">
            <ScrollViewer Padding="{TemplateBinding Padding}" Focusable="False">
                <ItemsPresenter SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}" />
            </ScrollViewer>
        </Border>
    </ControlTemplate>
</ListView.Template>
