Hello,
Please note I'm also running the following code during application startup:
SfSkinManager.ApplyStylesOnApplication = true;
SfSkinManager.SetVisualStyle(mainWindow, VisualStyles.Office365);
During further testing, I've found that removing this code, fixes the issues. The Foreground color is now correctly applied on the Docking Manager header text.
I would however prefer to keep globally applying that VisualStyle, I still think this behaviour is unexpected.
Kind regards,
Floris Verhoeven
