How to change the color of inside circle of radio button in WPF XAML

Question

This is my radio button:

<RadioButton Content="Add" Grid.Column="1" Height="16" HorizontalAlignment="Left" Margin="50,13,0,0" Name="rdAdd" VerticalAlignment="Top" GroupName="AddEditRadio" Checked ="rdAdd_Checked" FontSize="12.667" />

Now the color of inner circle of radio button is orange.I want to change it to blue.

Which property do I set to get "Blue" color?

Answer 1

I'm afraid there is no direct property you can use to change the color.
What you need to do is reTemplate the RadioButton to whatever you would like.

Luckily, the default templates are available, here is the one for the RadioButton.

If I understand correctly what you want to change, you should probably modify the color of the CheckMark (or the entire BulletDecorator depends what you're trying to achieve).

Answer 2

<RadioButton Content="Add" Background="Blue" Foreground="Green" BorderBrush="Red" BorderThickness="5" />

(i added BorderThickness of 5 to make it easier to see)

This will change the background color of the radio button to blue, the text "ADD" to green, and the border (around the button) red, like this:

These are the only colors you can directly change from Radio button (without using templates and such)
