How can I change the background and foreground colors of a WPF Textbox programmatically in C#?
textBox1.Background = Brushes.Blue;
textBox1.Foreground = Brushes.Yellow;
WPF Foreground and Background is of type System.Windows.Media.Brush
. You can set another color like this:
using System.Windows.Media;
textBox1.Background = Brushes.White;
textBox1.Background = new SolidColorBrush(Colors.White);
textBox1.Background = new SolidColorBrush(Color.FromArgb(0xFF, 0xFF, 0, 0));
textBox1.Background = System.Windows.SystemColors.MenuHighlightBrush;
