Customizing Radio buttons UWP - xaml

Question

I am trying to customize my radio buttons such that the outer ellipse is black and the inner circle fill is black when selected. In addition, i want to also change the font weight of the selected item to bold.
Currently i have the outer ellipse as black and inner circle as black but when i hover over it i can see it change to the default behavior of the button. My code is as follows:
<Style x:Key="RadioButtonStyle1" TargetType="RadioButton">
<Setter Property="Background" Value="{ThemeResource RadioButtonBackground}"/>
<Setter Property="Foreground" Value="{ThemeResource RadioButtonForeground}"/>
<Setter Property="BorderBrush" Value="{ThemeResource RadioButtonBorderBrush}"/>
<Setter Property="Padding" Value="8,6,0,0"/>
<Setter Property="HorizontalAlignment" Value="Left"/>
<Setter Property="VerticalAlignment" Value="Center"/>
<Setter Property="HorizontalContentAlignment" Value="Left"/>
<Setter Property="VerticalContentAlignment" Value="Top"/>

How do i make sure the properties i set are preserved when i hover over the radio buttons and how do i make the selected option appear bold.

Answer 1

i want to also change the font weight of the selected item to bold.
If you want to edit the content font weight when selected, you could add DiscreteObjectKeyFrame into checked VisualState like the following.
<VisualState x:Name="Checked">
<Storyboard>
<DoubleAnimation
Storyboard.TargetName="CheckGlyph"
Storyboard.TargetProperty="Opacity"
To="1"
Duration="0" />
<DoubleAnimation
Storyboard.TargetName="OuterEllipse"
Storyboard.TargetProperty="Opacity"
To="0"
Duration="0" />
<DoubleAnimation
Storyboard.TargetName="CheckOuterEllipse"
Storyboard.TargetProperty="Opacity"
To="1"
Duration="0" />
<ObjectAnimationUsingKeyFrames Storyboard.TargetName="ContentPresenter" Storyboard.TargetProperty="FontWeight">
<DiscreteObjectKeyFrame KeyTime="0" Value="Bold" />
</ObjectAnimationUsingKeyFrames>
</Storyboard>
</VisualState>
Currently i have the outer ellipse as black and inner circle as black but when i hover over it i can see it change to the default behavior of the button.
During the testing, we have not reproduce this behavior, you could check PointerOver VisualState and edit the matched element background when cursor point over.
