无法在 WPF 中完全设置 ListBox/Scrollviewer 的样式

问题描述

我正在使用我们使用标准 ControlTemplates 创建的自定义滚动条，但是当我将它们应用到 ListBox 时，右下角有一个角，我无法找到任何方法来覆盖它.

I'm using custom Scrollbars we created using standard ControlTemplates, however when I apply them to a ListBox there is a corner in the bottom right which I am unable to find any way to override.

很遗憾，在获得更多积分之前，我无法发布图片.但是我指的角落是当垂直和水平滚动条都出现时，右下角有一个空间，填充了我无法覆盖的灰白色

Unfortunately I can't post a picture until I get more points. But the corner I'm referring to is when both a vertical and horizontal scrollbar appear, there is a space in the bottom right that is filled with an off-white color that I am unable to ovrerride

推荐答案

这是我使用 Blend 获得的 ScrollViewer 模板代码的一部分.我在右下角添加了一个矩形并将填充设置为红色.您可以以相同的方式对其进行样式设置，也可以使用 Grid.RowSpan="2" 为 VerticalScrollBar(第一个)或 Grid.ColumnSpan="2" 为 Horizo​​ntalScrollBar(第二个)扩展其中一个 ScrollBar 以覆盖空间.

this is the part of the template code i got for ScrollViewer using Blend. I added a Rectangle in the bottom right corner and set the Fill to Red. You can style it in the same way or you can expand one of the ScrollBar to cover the space using Grid.RowSpan="2" for VerticalScrollBar(first one) or Grid.ColumnSpan="2" for HorizontalScrollBar(second one).

<Style TargetType="{x:Type ScrollViewer}">
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="{x:Type ScrollViewer}">
                <Grid>
                    <Grid.ColumnDefinitions>
                        <ColumnDefinition/>
                        <ColumnDefinition Width="Auto"/>
                    </Grid.ColumnDefinitions>
                    <Grid.RowDefinitions>
                        <RowDefinition/>
                        <RowDefinition Height="Auto"/>
                    </Grid.RowDefinitions>
                    <ScrollContentPresenter Grid.Column="0"/>
                    <ScrollBar Name="PART_VerticalScrollBar" Grid.Row="0" Grid.Column="1" Value="{TemplateBinding VerticalOffset}" Maximum="{TemplateBinding ScrollableHeight}" ViewportSize="{TemplateBinding ViewportHeight}" Visibility="{TemplateBinding ComputedVerticalScrollBarVisibility}"/>
                    <ScrollBar Name="PART_HorizontalScrollBar" Orientation="Horizontal" Grid.Row="1" Grid.Column="0" Value="{TemplateBinding HorizontalOffset}" Maximum="{TemplateBinding ScrollableWidth}" ViewportSize="{TemplateBinding ViewportWidth}" Visibility="{TemplateBinding ComputedHorizontalScrollBarVisibility}"/>
                    <Rectangle Grid.Row="1" Grid.Column="1" Fill="Red"/>
                </Grid>
            </ControlTemplate>
        </Setter.Value>
    </Setter>
</Style>
