我在Windows应用商店应用程序项目上有以下代码。
<Grid x:Name="minutesGrid" Height="1000" Width="1024" Background="White" >
<Grid.RowDefinitions>
<RowDefinition Height="20"/>
<RowDefinition Height="50"/>
<RowDefinition Height="100"/>
<RowDefinition Height="750"/>
<RowDefinition Height="30"/>
</Grid.RowDefinitions>
<StackPanel Grid.Row="1" Background="White" Height="50" Orientation="Vertical" >
<TextBlock x:Name="minutesTitle" Text="" FontFamily="Segoe UI Semilight" FontWeight="SemiLight" FontSize="24" TextAlignment="Center" Foreground="{StaticResource BrandBrush}" Margin="0,15,0,0"></TextBlock>
</StackPanel>
<StackPanel Grid.Row="2" Background="White">
<ScrollViewer HorizontalScrollBarVisibility="Disabled" HorizontalScrollMode="Disabled" VerticalScrollMode="Enabled" VerticalScrollBarVisibility="Visible" Height="100">
<TextBlock x:Name="minutesDesc" Text="" FontFamily="Segoe UI Semilight" FontWeight="SemiLight" FontSize="24" Foreground="{StaticResource BrandBrush}" Margin="15,15,0,0" TextWrapping="WrapWholeWords"></TextBlock>
</ScrollViewer>
</StackPanel>
<StackPanel Grid.Row="3" Background="White">
<PdfViewer:SfPdfViewerControl x:Name="minutesPDF" Canvas.ZIndex="1"/>
</StackPanel>
</Grid>
当我加载 pdf 时，它不显示滚动条或让我用鼠标滚轮或在平板电脑上用手指进行滚动。
这就是我如何加载正确显示的文件。
var datapdf = await objService。download file service(" test . pdf "，minutes . gapp file . _ id)；
PdfLoadedDocument pdf = new PdfLoadedDocument(Convert.FromBase64String(datapdf));
await minutesPDF.LoadDocumentAsync(pdf);
minutesPDF.ViewMode = Syncfusion.Windows.PdfViewer.PageViewMode.Normal;
我需要添加其他东西吗？
我认为您必须移除堆栈面板并分配网格。PDFViewer的行..

由于StackPanel具有沿一个方向增长的默认行为，因此在未设置高度属性的情况下，无法启动StackPanel中包含的控件的滚动。
请找到以下链接，该链接说明了“为什么控件无法在不设置其高度属性的情况下在 StackPanel 中滚动？
如何让ScrollViewer在StackPanel中工作？
