Add border to radioButton with text on isChecked - wpf

Question

I want to add border to radiobutton with text on isChecked
I tried Style.Trigger but it didn't seem to have action
Also tried via ControlTemplate.Trigger but referencing to both grid and text box says Parameter is not recognized

The TextBlock doesn't have a border, so it's impossible to set a value for the border either.
It can be solved in two ways.
Use instead of TextBlock element TextBox in read-only mode.
<ControlTemplate TargetType="RadioButton">
<Grid VerticalAlignment="Stretch"
HorizontalAlignment="Stretch"
Background="{TemplateBinding Background}"
x:Name="GridMain">
<TextBox Text="{TemplateBinding Content}"
x:Name="ButtonText"
VerticalAlignment="Center"
Margin="20,0,0,0"
IsReadOnly="True"/>
</Grid>
<ControlTemplate.Triggers>
<Trigger Property="IsChecked" Value="True">
<Setter TargetName="ButtonText" Property="Margin" Value="30,0,0,0"></Setter>
<Setter TargetName="ButtonText" Property="BorderThickness" Value="5"/>
</Trigger>
<Trigger Property="IsMouseOver" Value="True">
<Setter TargetName="GridMain" Property="Background" Value="#424549"></Setter>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
Since you have only one element in the panel, you can use Border instead.
<ControlTemplate TargetType="RadioButton">
<Border VerticalAlignment="Stretch"
HorizontalAlignment="Stretch"
Background="{TemplateBinding Background}"
x:Name="GridMain">
<TextBlock Text="{TemplateBinding Property=Content}"
x:Name="ButtonText"
VerticalAlignment="Center"
Margin="20,0,0,0">
</TextBlock>
</Border>
<ControlTemplate.Triggers>
<Trigger Property="IsChecked" Value="True">
<Setter TargetName="ButtonText" Property="Margin" Value="30,0,0,0"></Setter>
<Setter TargetName="GridMain" Property="BorderThickness" Value="5"/>
</Trigger>
<Trigger Property="IsMouseOver" Value="True">
<Setter TargetName="GridMain" Property="Background" Value="#424549"></Setter>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
