Setting or modifying ThemeResource in code

Question

My questions is very specific to ThemeResources in a Windows 10 Store App. Unfortunately several things available in \"classic\" WPF are different or not available here.

Answer 1

In Windows 10, the name "Accent Color" is changed to "SystemControlHighlightAccentBrush", and it's a ThemeResource

Example using it

To override it, simply change value of it in App.xaml

To switch, it's a little bit more difficult First, you need to set all the color for each theme in App.xaml

Then, in the page or in code behind, you set the corresponding theme

or in C#

TestTextBlock.RequestedTheme = ElementTheme.Dark;
