滚动条和...文本框的奇怪问题？ （垂直内容对齐）

Question

我有这个奇怪的问题，我不明白是什么原因造成的。在我的整个项目中，文本框无法垂直居中，无论我使用什么，填充，VerticalContentAlignment，或者任何你能想到的其他东西，水平都可以正常工作。

然后我觉得可能是某个资源干扰了我的文本框，所以我开始一一删除，直到找到导致这个问题的资源，这是我在互联网上找到的自定义滚动条，读了大约10遍后，我刚刚放弃了。你们能帮我了解该资源的哪一部分导致了这个问题吗？

Answer 1

事实证明，滚动查看器中有一个名为 x:Name="Corner" 的矩形，我不知道，再次浏览互联网后，我发现了这个问题，这确实解决了我的问题，通过替换我的资源中的最后两个样式（我最初添加它们是因为我从互联网上获得的资源有它，并且它还解决了当两个滚动条可见时在右下角生成的空方块的烦人问题） 现在，当我这么说时，所有文本框都在中间完美对齐。

这是我更换的新样式：

<Style TargetType="ScrollViewer">
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="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" Grid.Row="1"
                Fill="Transparent"/>
                    <ScrollContentPresenter x:Name="PART_ScrollContentPresenter"
                            Grid.Column="0" Grid.Row="0"
                            CanContentScroll="{TemplateBinding CanContentScroll}"
                            CanHorizontallyScroll="False" CanVerticallyScroll="False"
                            ContentTemplate="{TemplateBinding ContentTemplate}"
                            Content="{TemplateBinding Content}"
                            Margin="{TemplateBinding Padding}"/>
                    <ScrollBar x:Name="PART_VerticalScrollBar"
