如何阻止点击scrollviewer里面的单位内容时，自动滚动

 <Style TargetType="{x:Type ListBoxItem}">

 <Setter Property="FocusVisualStyle" Value="{x:Null}" />

 <Setter Property="Background" Value="Transparent" />

 <EventSetter Event="RequestBringIntoView" Handler="OnRequestBringIntoView" />//这句话起作用

 <Setter Property="Template">

 <Setter.Value>

 <ControlTemplate TargetType="{x:Type ListBoxItem}">

 <ContentPresenter HorizontalAlignment="Stretch"

 VerticalAlignment="Stretch"

 SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}" />

 </ControlTemplate>

 </Setter.Value>

 </Setter>

 </Style>

 //cs代码

 private void OnRequestBringIntoView(object sender, RequestBringIntoViewEventArgs e)

         {

             e.Handled = true;

         }
