How to change the background color of button on Cl

Question

I'm working on a UWP app in windows 10 and I am trying to change the background color of a button in a click event. This is my code:

private void button1_1_Click(object sender, RoutedEventArgs e)
{
    if (_Sign)
    {
        button_1_1.Content = "Cross";
        _Sign = false;
    }
    else
    {
        // button_1_1.Background = new SolidColorBrush(new Windows.UI.Color )    

        // indows.UI.Colors clr = new Windows.UI.Colors(new SolidColorBrush red);

        // SolidColorBrush color = new SolidColorBrush();
        // color = new SolidColorBrush.
        // button_1_1.Background = clr;

        button_1_1.Content = "Tick";
        _Sign = true;
    }
}

Answer 1

Use the predefined color objects from the Colors properties:

button_1_1.Background = new SolidColorBrush(Windows.UI.Colors.White);

Answer 2

You can also provide different color

 SolidColorBrush mySolidColorBrush = new SolidColorBrush();
   mySolidColorBrush.Color = Color.FromArgb(0, 255, 244, 244);
 button1.Background = mySolidColorBrush;

U have to just convert a color code to Argb like this

return new SolidColorBrush(
                Color.FromArgb(
                    255,
                    Convert.ToByte(hexaColor.Substring(1, 2), 16),
                    Convert.ToByte(hexaColor.Substring(3, 2), 16),
                    Convert.ToByte(hexaColor.Substring(5, 2), 16)
                )
            );

its very easy and proper because you can give any color not a default color like black ,orange etc.

Answer 3

You can do just that

button1.SetValue(BackgroundProperty,new SolidColorBrush(Windows.UI.Colors.Black));

You can play with that! I am not on my pc now to check it but something like that works.

or you can try

button1.Background = new SolidColorBrush(Windows.Ui.Colors.Black);
