Wpf 无背景滚动查看器
我想问你是否有人知道如何创建无背景的ScrollViewer。我知道使用样式或模板（我猜）是不可能的，必须从ScrollVewer创建新组件，但我找不到哪个方法/属性重写 例如：Wpf 无背景滚动查看器,wpf,background,scrollviewer,Wpf,Background,Scrollviewer,我想问你是否有人知道如何创建无背景的ScrollViewer。我知道使用样式或模板（我猜）是不可能的，必须从ScrollVewer创建新组件，但我找不到哪个方法/属性重写 例如： <Window x:Class="WpfScroll.MainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/

-pav-您可以处理ScrollViewer的PreviewMouseDown事件。 在您的xaml中：
<Grid>
<!--Button is removed as it will be not used-->
<ScrollViewer Background="{x:Null}" Margin="20" PreviewMouseDown="ScrollViewer_MouseDown">
<StackPanel Orientation="Horizontal" Background="{x:Null}">
<Rectangle Fill="Red" Width="100" Margin="50"></Rectangle>
<Rectangle Fill="Red" Width="100" Margin="50"></Rectangle>
<Rectangle Fill="Red" Width="100" Margin="50"></Rectangle>
<Rectangle Fill="Red" Width="100" Margin="50"></Rectangle>
</StackPanel>
</ScrollViewer>
</Grid>
