c# - WPF Bool DataTrigger - Change Font Colour -

I want to change the font color of many items on a WPF page based on the user-selected theme. (A light subject, and a deep subject)

I am using a database template to customize the contents of the list of contents, when the subject is dark, then I will use all the textblocks of the font colors as white I want to change in

In my previous class I am setting the dark theme as truth.

I have successfully set triggers down, although I

So, I textblocks to white Can the font color style give if DarkTheme = true

code:?

  Public Partial Media Media: UserControl {public bool darkTheme {get; Set; } Readonly DatabaseAsset _dbAssets = new DatabaseAsset (); Public Media () {InitializeComponent (); RefreshMediaList (); Darkthim = Global. Configuration. DarkModeAppleldEtheme (); }}

 This is not the right way to themed into WPF.  
 But if you want a quick solution,  Move InitializeComponent ()  statement to the bottom of its manufacturer:  
  public media () { RefreshMediaList (); Darkthim = Global. Configuration. DarkModeAppleldEtheme (); InitializeComponent (); // & lt; - here}
