Question

我有一个比它的窗口容器大的图像，它被放置在ScrollViewer中，但是，图像根本不滚动。我已经尝试将图像放在一个没有运气的容器中。我在这里缺少什么设置？（我直接从MS复制代码，但是他们错了）

以下是代码：

<Window
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:h="http://helixtoolkit.codeplex.com" x:Class="TileLayout"
Title="TileLayout" Height="1000" Width="845" WindowStartupLocation="CenterScreen" WindowStyle="ThreeDBorderWindow">
<StackPanel HorizontalAlignment="center" VerticalAlignment="Top">
    <StackPanel Orientation="Horizontal"   >
        <TextBox x:Name="txtSourceFilePath" Width="500" Margin="10" Height="22" TextChanged="TextBox_TextChanged" Text="E:\projects\Test3D\SavedSnapshots\snapshot.png"/>
        <Button x:Name="btnPickFile" Width="100" Margin="0,10,10,10" Content="Pick File" ></Button>
    </StackPanel>
    <ScrollViewer VerticalScrollBarVisibility="Auto" >
        <Image x:Name="imgFinal" Source="SteelMotion_chevron2.png"/>
    </ScrollViewer>
</StackPanel>

Answer 2

您需要指定ScrollViewer的大小。在这种情况下，ScrollViewer和Image的大小相同，因此滚动条不显示。

ScrollViewer不会滚动图像WPF
