触摸屏上客户要求滚动条宽度大些，方便手指上下滚动，之前在网上看了个，原文找不到了，代码记录下。
效果如下：
<ControlTemplate x:Key="ScrollViewerControlTemplate1" TargetType="{x:Type ScrollViewer}"> <Grid x:Name="Grid" Background="{TemplateBinding Background}"> <Grid.ColumnDefinitions> <ColumnDefinition Width="*"/> <ColumnDefinition Width="Auto"/> Grid.ColumnDefinitions> <ScrollContentPresenter x:Name="PART_ScrollContentPresenter" CanContentScroll="{TemplateBinding CanContentScroll}"
