问题描述
大家好，
我有这种WPF风格：
< 样式 TargetType = RadioButton x：名称 = 切换 >
< Setter 属性 = 模板 >
< ; Setter.Value >
< ControlTemplate >
< 边框 BorderBrush = {TemplateBinding BorderBrush} BorderThickness = {TemplateBinding BorderThickness} >
< 网格 >
< 矩形 >
< Rectangle.Style >
< 样式 TargetType = 矩形 >
< Style.Triggers >
< 触发器 属性 = IsChecked 值 = True >
< Setter 属性 = 填写 值 = {TemplateBinding Foreground} / >
< / Trigger >
< 触发器 属性 = IsChecked < span class =code-attribute> 值 = False >
< Setter 属性 = 填写 值 = {TemplateBinding Background} / >
< / Trigger >
< / Style.Triggers >
< < span class =code-leadattribute> / Style >
< / Rectangle.Style >
< ; / Rectangle >
< ContentPresenter / >
< / Grid >
< / Border >
< / ControlTemplate >
< / Setter.Value >
< / Setter >
< / Style >
这些行：
< 触发器 属性 = IsChecked 值 = < span class =code-keyword> True >
< Setter Property = 填写 值 = {TemplateBinding Foreground} / >
< / Trigger >
< 触发器 属性 = IsChecked 值 = 错误 >
< Setter 属性 = 填写 值 = {TemplateBinding Background} / >
< / Trigger >
不起作用，因为它们嵌套在矩形而不是Radiobutton中。
如何触发参考RadioButton？
非常感谢!!

Hi everybody,
I have this WPF style:
<Style TargetType="RadioButton" x:Name="Toggle">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate>
<Border BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}">
<Grid>
<Rectangle>
<Rectangle.Style>
<Style TargetType="Rectangle">
<Style.Triggers>
<Trigger Property="IsChecked" Value="True">
<Setter Property="Fill" Value="{TemplateBinding Foreground}" />
</Trigger>
<Trigger Property="IsChecked" Value="False">
<Setter Property="Fill" Value="{TemplateBinding Background}" />
</Trigger>
</Style.Triggers>
</Style>
</Rectangle.Style>
</Rectangle>
<ContentPresenter />
</Grid>
</Border>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
Those lines:
<Trigger Property="IsChecked" Value="True">
<Setter Property="Fill" Value="{TemplateBinding Foreground}" />
</Trigger>
<Trigger Property="IsChecked" Value="False">
<Setter Property="Fill" Value="{TemplateBinding Background}" />
</Trigger>
Do not work as they are nested in a Rectangle and not in the Radiobutton.
How can I make the trigger refer to the RadioButton?
Thanks a lot!!
