Property Value

The resource key for the Color of text in a window's client area.

Use the WindowTextColorKey to create a dynamic reference to the window text system color. This dynamic reference will automatically update if the color is changed. To create a static reference that won't update automatically, use WindowTextColor.

To use a system color in a gradient, you use the <SystemColor>Color and <SystemColor>ColorKey static properties of the SystemColors class to obtain a reference to the color, where <SystemColor> is the name of the desired system color. Use the <SystemColor>ColorKey properties when you want to create a dynamic reference that updates automatically as the system theme changes. Otherwise, use the <SystemColor>Color properties.

The following example uses dynamic system color resources to create a gradient.

         is running, the gradient will be updated
         automatically.  -->
    <Button Content="Hello, World!">

            <GradientStop Offset="1.0" 
              Color="{DynamicResource {x:Static SystemColors.ControlLightLightColorKey}}" />
          </LinearGradientBrush.GradientStops>
        </LinearGradientBrush>

The next example uses static system color resources to create a gradient.

    <!-- Uses static references to system colors to set
         the colors of gradient stops. 
         If these system colors change while this application
         is running, this button will not be updated until
         the page is loaded again. -->
    <Button Content="Hello, World!">
      <Button.Background>
        <LinearGradientBrush>
          <LinearGradientBrush.GradientStops>
            <GradientStop Offset="0.0" 
              Color="{x:Static SystemColors.DesktopColor}" />
            <GradientStop Offset="1.0" 
              Color="{x:Static SystemColors.ControlLightLightColor}" />
          </LinearGradientBrush.GradientStops>
        </LinearGradientBrush>
      </Button.Background>
    </Button>
