BorderThickness的边框控制无效 [英] BorderThickness of Border control doesn't work

问题描述

我已经定义了以下DataTemplate:

I have defined the following DataTemplate:

                    <dxg:TableView.DataRowTemplate>
                    <DataTemplate>
                        <StackPanel Orientation="Vertical">
                            <Border BorderThickness="0" BorderBrush="#D0C9A0" Style="{StaticResource borderStyle}">
                                <dx:MeasurePixelSnapper>
                                    <ContentControl Content="{Binding}" ContentTemplate="{Binding View.DefaultDataRowTemplate}"/>
                                </dx:MeasurePixelSnapper>
                            </Border>
                        </StackPanel>
                    </DataTemplate>
                </dxg:TableView.DataRowTemplate>

我想在行集中时应用这种样式:

And I want to apply this style when the row is focused:

        <Style TargetType="Border" x:Key="borderStyle">
        <Setter Property="BorderThickness" Value="0"/>
        <Style.Triggers>
            <Trigger Property="dxg:GridViewBase.IsFocusedRow" Value="True">
                <Setter Property="BorderThickness" Value="4"></Setter>
            </Trigger>
        </Style.Triggers>
    </Style>

为什么不起作用?我不明白为什么触发器要执行.有解决办法吗?

Why doesn't it work? I don't understand why the Trigger is noct executed. Any solution?

推荐答案

由< Border BorderThickness ="0" ...> 设置的本地属性值的优先级高于任何设置的值通过样式.因此，触发器设置的值会被静默忽略.

The local property value set by <Border BorderThickness="0" ...> has higher precedence than any value set by a Style. Hence the value set by the Trigger is silently ignored.

只需删除BorderThickness分配:

Just remove the BorderThickness assignment:

<Border BorderBrush="#D0C9A0" Style="{StaticResource borderStyle}">
    ...
</Border>

请参见相关性属性值优先级.
