Question

朋友，下面是我的代码。我不知道为什么我的滚动条不起作用。

<Window x:Class="Seris.Views.Help"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    Title="Help" Height="400" Width="400">
<DockPanel>
    <ScrollViewer VerticalScrollBarVisibility="Auto">
        <TextBlock HorizontalAlignment="Left" Margin="10,10,0,0" TextWrapping="Wrap" VerticalAlignment="Top" Height="350" Width="372"><InlineUIContainer>
                <Image Height="100" Width="100" RenderTransformOrigin="1.37,0.46" Source="../Images/help.jpg"/>
                </InlineUIContainer><Run/><LineBreak/><Run Text="There are some validations on the Vehicle Form as below."/><LineBreak/><Run Text="P"/><Run Text="lease note that all the fields are mandatory."/><LineBreak/><Run/><LineBreak/><Run FontWeight="Bold" Text="Vehicle No"/><LineBreak/><Run Text="It should be always 7 character long con"/><Run Text="taining "/><Run Text="first 3 digits as alphabet in capital form and remaining 4 numerical.

        </TextBlock>
    </ScrollViewer>
</DockPanel>
</Window>

Answer 1

删除Height="350"＆amp;来自TextBlock的Width="372"，这些阻止了ScrollViewer正常工作

如果要限制大小，可以根据需要将其应用于DockPanel或ScrollViewer。

因此，如果您将宽度或高度应用于TextBlock将限制元素的大小，并且ScrollViewer可能无法按预期工作。

另外，您也可以删除HorizontalAlignment="Left"＆amp;来自TextBlock的VerticalAlignment="Top"因为它们可能也不是必需的

ScrollViewer不适用于WPF中的TextBlock
