Hi Try the below code private void TextBox1_GotFocus(object sender RoutedEventArgs e) { SolidColorBrush brush = (sender as TextBox).Foreground as SolidColorBrush; if (null != brush) { brush.Color = Colors.Red; } } private void TextBox1_LostFocus(object sender RoutedEventArgs e) { SolidColorBrush brush = (sender as TextBox).Foreground as SolidColorBrush; if (null != brush) { brush.Color = Colors.Blue; } } For detail check the link https://social.msdn.microsoft.com/Forums/windowsapps/en-US/8c7b9f8e-43e2-476f-b974-6cb1d268647e/how-to-set-foreground-color-in-textbox-for-focused-state?forum=wpdevelop https://msdn.microsoft.com/en-us/library/windows/apps/mt299154.aspx http://stackoverflow.com/questions/38216537/how-to-change-border-color-of-textbox-on-focus-in-uwp
