【问题描述】：
我的 WPF 应用程序中有一些错误检查。错误信息显示在文本框旁边，但当文本框在应用程序右侧时，它不会显示所有错误文本。
结果：
这是我的错误模板样式：
<ControlTemplate x:Key="errorTemplateStyle">
<StackPanel Orientation="Horizontal">
<Border BorderThickness="1" BorderBrush="#FFdc000c" CornerRadius="0.7"
VerticalAlignment="Top">
<Grid>
<Polygon x:Name="toolTipCorner"
Grid.ZIndex="2"
Margin="-1"
Points="6,6 6,0 0,0"
Fill="#FFdc000c"
HorizontalAlignment="Right"
VerticalAlignment="Top"
IsHitTestVisible="True"/>
<Polyline Grid.ZIndex="3"
Points="7,7 0,0" Margin="-1" HorizontalAlignment="Right"
StrokeThickness="1.5"
StrokeEndLineCap="Round"
StrokeStartLineCap="Round"
Stroke="White"
VerticalAlignment="Top"
IsHitTestVisible="True"/>
<AdornedElementPlaceholder x:Name="adorner"/>
</Grid>
</Border>
<Border x:Name="errorBorder" Background="#FFdc000c" Margin="1,0,0,0"
Opacity="0" CornerRadius="1.5"

<Border.Effect>
<DropShadowEffect ShadowDepth="2.25"

</Border.Effect>
<TextBlock Text="{Binding ElementName=adorner,
Path=AdornedElement.(Validation.Errors)[0].ErrorContent}"
Foreground="White" Margin="8,3,8,3" TextWrapping="Wrap"/>
</Border>
</StackPanel>
<ControlTemplate.Triggers>
<DataTrigger Value="True">
<DataTrigger.Binding>
<MultiBinding Converter="{StaticResource BooleanOrConverter}">
<Binding ElementName="adorner" Path="AdornedElement.IsKeyboardFocused" />

</MultiBinding>
</DataTrigger.Binding>
<DataTrigger.EnterActions>

<Storyboard>
<DoubleAnimation Duration="00:00:00.15"

Storyboard.TargetName="errorBorder"
Storyboard.TargetProperty="Margin"
FillBehavior="HoldEnd"
From="1,0,0,0"
To="5,0,0,0">
<ThicknessAnimation.EasingFunction>
<BackEase EasingMode="EaseOut" Amplitude="2"/>
</ThicknessAnimation.EasingFunction>
</ThicknessAnimation>
</Storyboard>
</BeginStoryboard>
</DataTrigger.EnterActions>
<DataTrigger.ExitActions>
<StopStoryboard BeginStoryboardName="fadeInStoryboard"/>
<BeginStoryboard x:Name="fadeOutStoryBoard">
<Storyboard>
<DoubleAnimation Duration="00:00:00"
Storyboard.TargetName="errorBorder"
Storyboard.TargetProperty="Opacity"
To="0"/>
</Storyboard>
</BeginStoryboard>
</DataTrigger.ExitActions>
</DataTrigger>
</ControlTemplate.Triggers>
</ControlTemplate>
你能帮我如何显示所有错误信息吗？
谢谢雅库布
