#226 – Gradient Fills Adjust to the Size of the Control

Because the start/stop points and gradient stops within a gradient fill are normalized to a 0.0-1.0 range, the same gradient can be used to fill controls of different sizes.  The fill changes color proportionally, relative to the size of the control, rather than at specific pixel positions.

In the example below, we define a linear gradient brush and then apply it to several controls of different sizes.

	<Window.Resources>
		<LinearGradientBrush x:Key="HappyFill" StartPoint="0,0.5" EndPoint="1,0.5">
		    <GradientStop Color="AliceBlue" Offset="0.0"/>
		    <GradientStop Color="Chocolate" Offset="1.0"/>
		</LinearGradientBrush>
	</Window.Resources>

	<StackPanel>
		<Rectangle Height="100" Width="200" Fill="{StaticResource HappyFill}" Margin="30"/>
		<Button Content="!" Width="25" Background="{StaticResource HappyFill}" Height="25"/>
		<Label Content="We few, we happy few, we band of brothers.  --Hal V"
			HorizontalAlignment="Center" Margin="15"
			Background="{StaticResource HappyFill}"/>
	</StackPanel>
