问题描述

我正在开发UWP应用，并且正在使用Template10. 我有一个TextBlock，在VisualStateNarrow中我想要它RelativePanel.AlignVerticalCenterWithPanel="True"，在NormalMinWidth中我想要RelativePanel.AlignHorizontalCenterWithPanel="True"，但是我不能这样做！

I am develop an UWP app, and I am using Template10. I have an TextBlock, that in VisualStateNarrow I want it RelativePanel.AlignVerticalCenterWithPanel="True" and in NormalMinWidth I want RelativePanel.AlignHorizontalCenterWithPanel="True" but I can not do this!

<VisualStateManager.VisualStateGroups>
                <VisualStateGroup x:Name="AdaptiveVisualStateGroup">
                    <VisualState x:Name="VisualStateNarrow">
                        <VisualState.StateTriggers>
                            <AdaptiveTrigger MinWindowWidth="{StaticResource NarrowMinWidth}"/>
                        </VisualState.StateTriggers>
                        <VisualState.Setters>

                           <Setter Target="TextBlock.RelativePanel.AlignVerticalCenterWithPanel="True"/>

                        </VisualState.Setters>
                    </VisualState>
                    <VisualState x:Name="VisualStateNormal">
                        <VisualState.StateTriggers>
                            <AdaptiveTrigger MinWindowWidth="{StaticResource NormalMinWidth}"/>
                        </VisualState.StateTriggers>
                        <VisualState.Setters>

                          <Setter Target="TextBlock.RelativePanel.AlignHorizontalCenterWithPanel="True"/>

                        </VisualState.Setters>
                    </VisualState>
                    <VisualState x:Name="VisualStateWide">
                        <VisualState.StateTriggers>
                            <AdaptiveTrigger MinWindowWidth="{StaticResource WideMinWidth}"/>
                        </VisualState.StateTriggers>
                        <VisualState.Setters>
                        </VisualState.Setters>
                    </VisualState>
                </VisualStateGroup>
            </VisualStateManager.VisualStateGroups>

在XAML编辑器中，给我这个错误:引发了异常." -无法在指定对象上解析TargetProperty RelativePanel.AlignHorizo​​ntalCenterWithPanel."

In XAML editor give me this error: "An Exception was thrown." - "Cannot resolve TargetProperty RelativePanel.AlignHorizontalCenterWithPanel on specified object."

我有很多Setter.Target，它们都可以工作！ 我的Setter.Target的示例:

I have many Setter.Target and they all work! Example of my Setter.Target:

<Setter Target="TextBlock.Margin" Value="8"/>
<Setter Target="TextBlock.Width" Value="200"/>
<Setter Target="TextBlock.Height" Value="200"/>

推荐答案

对于附加属性，您必须按如下方法在方括号中添加方括号:

For attached properties you have to add brackets to in setters as follows:

Element.(Grid.Row)
Element.(ToolTipService.ToolTip)

因此您的代码将如下所示:

So your code will look like this:

<Setter Target="TextBlock.(RelativePanel.AlignVerticalCenterWithPane‌​l)" Value="True" />
