Setting background of panel with custom color code
I think this sample helps you for xaml solution;
<Border.Background>
<LinearGradientBrush EndPoint="1.204,0.5" StartPoint="0.056,0.5">
<GradientStop Color="#FFFFFFFF" Offset="0" />
<GradientStop Color="#FFD4D7DB" Offset="1" />
</LinearGradientBrush>
</Border.Background>
The following oneliner should work.
something.Background = (Brush)new BrushConverter().ConvertFrom("#C7DFFC");
BrushConverter bc = new BrushConverter();
stackPanelFlasher.Background= (Brush)bc.ConvertFrom("#C7DFFC");
Should do the job. If you want to make it waterproof, better would be
BrushConverter bc = new BrushConverter();
Brush brush=(Brush)bc.ConvertFrom("#C7DFFC");
brush.Freeze();
stackPanelFlasher.Background=brush;
needs fewer resources...
stackPanelFlasher.Background = new SolidColorBrush(Color.FromArgb(alpha, red, green, blue));
