Is it possible to change PhoneTextNormalStyle from code behind ? I tried in ways but no luck.
I have already used this style in many places in my app . Now i want to change foreground color . How can i do this without changing all the places in xaml
You can create a custom style on your App.xaml based on the PhoneTextNormalStyle and just adapt the Foreground to suit your needs:
<Style x:Key="RedPhoneTextNormalStyle" BasedOn="{StaticResource PhoneTextNormalStyle}">
<Setter Property="Foreground" Value="Red"/>
</Style>
Then adapting the current style calls to the new one should be fairly easy (search & replace)
<TextBlock x:Name="ApplicationTitle"
Text="APP NAME"
Style="{StaticResource RedPhoneTextNormalStyle}"/>
The advantage of using a custom style is that you can always extend it if you need to add more functionality to it, as well as use it as a base for other styles
