I think you did not understand me.
My application already uses "StyleManager.ApplicationTheme = new MetroTheme
();" in App.xaml.cs
I already use several controls "RadControls" in my application.
I want to create new controls (non-existent in RadControls) using the color patterns that are active in "StyleManager.ApplicationTheme."
For example: I want to create a control that has a "rectangle" with the background color of a "RadButton" and border color of the border "RadMaskedTextBox."
Style style = StyleManager.ApplicationTheme.GetStyle("RadButton");
Brush brush = style.GetSetter("Background");
MyControl control.Background = brush;
