c# – 如何仅使用xaml在scrollviewer中设置滚动条的余量

概述我需要在滚动查看器中设置滚动条的边距. 我尝试在默认的scrollviewer样式中重写滚动条边距.只需修改样式中的边距,滚动条magin设置正确的值.但滚动条移动时,scrollviewer中的内容会保持静态.我该如何修复它还是有另一种方法来设置scrollviewer中滚动条的余量更容易吗？ <Style TargetType="ScrollViewer"> <Setter Propert 我需要在滚动查看器中设置滚动条的边距.

解决方法 我为垂直Scrollbar制作了margin =“10,10,20”,它工作得很好.
ScrollVIEwer包含一个用于测试目的的DataGrID.

XAML：

<ScrollVIEwer HorizontalAlignment="left" Height="152" margin="25,42,0" VerticalAlignment="top" WIDth="449">        <ScrollVIEwer.Template>            <ControlTemplate targettype="{x:Type ScrollVIEwer}">                <GrID x:name="GrID" Background="{TemplateBinding Background}">                    <GrID.ColumnDeFinitions>                        <ColumnDeFinition WIDth="*"/>                        <ColumnDeFinition WIDth="auto"/>                    </GrID.ColumnDeFinitions>                    <GrID.RowDeFinitions>                        <RowDeFinition Height="*"/>                        <RowDeFinition Height="auto"/>                    </GrID.RowDeFinitions>                    <Rectangle x:name="Corner" GrID.Column="1" Fill="{DynamicResource {x:Static Systemcolors.ControlBrushKey}}" GrID.Row="1"/>                    <ScrollContentPresenter x:name="PART_ScrollContentPresenter" CanContentScroll="{TemplateBinding CanContentScroll}" CanHorizontallyScroll="False" CanVerticallyScroll="False" ContentTemplate="{TemplateBinding ContentTemplate}" Content="{TemplateBinding Content}" GrID.Column="0" margin="{TemplateBinding padding}" GrID.Row="0"/>                    <Scrollbar x:name="PART_VerticalScrollbar" automationPropertIEs.automationID="VerticalScrollbar" Cursor="Arrow" GrID.Column="1" Maximum="{TemplateBinding ScrollableHeight}" Minimum="0" GrID.Row="0" Visibility="{TemplateBinding ComputedVerticalScrollbarVisibility}" Value="{Binding VerticalOffset,Mode=OneWay,relativeSource={relativeSource TemplatedParent}}" VIEwportSize="{TemplateBinding VIEwportHeight}" margin="10,20"/>                    <Scrollbar x:name="PART_HorizontalScrollbar" automationPropertIEs.automationID="HorizontalScrollbar" Cursor="Arrow" GrID.Column="0" Maximum="{TemplateBinding ScrollableWIDth}" Minimum="0" OrIEntation="Horizontal" GrID.Row="1" Visibility="{TemplateBinding ComputedHorizontalScrollbarVisibility}" Value="{Binding HorizontalOffset,relativeSource={relativeSource TemplatedParent}}" VIEwportSize="{TemplateBinding VIEwportWIDth}"/>                </GrID>            </ControlTemplate>        </ScrollVIEwer.Template>        <DataGrID x:name="dataGrID" ItemsSource="{Binding Mode=OneWay}">            <DataGrID.DataContext>                <local:MyDataCollection/>            </DataGrID.DataContext>        </DataGrID>    </ScrollVIEwer>
