In my WPF application, I want to have an ambient animated background similar to Media Center's background. Is there a free control that offers this?

推荐答案

我想preFER通过故事板动画边框的背景。这是pretty容易，只要你喜欢，你可以建立一个动画一样复杂。下面是一个简单的例子：

I would prefer to animate the background of a border via storyboard. It's pretty easy and you can build a animation as complex as you like. Here is a short example:

<Window x:Class="WpfApplication1.Window1"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    Title="Window1" Height="300" Width="300">
    <Window.Triggers>
        <EventTrigger RoutedEvent="Window.Loaded">
            <BeginStoryboard>
                <Storyboard AutoReverse="True" BeginTime="0" >
                    <DoubleAnimation Storyboard.TargetName="Foo"
                                     Storyboard.TargetProperty="Offset"
                                     From="0.2" To="0.8" Duration="0:0:10"/>
                </Storyboard>
            </BeginStoryboard>
        </EventTrigger>
    </Window.Triggers>
    <Border>
        <Border.Background>
            <LinearGradientBrush StartPoint="0,0" EndPoint="1,1">
                    <GradientStop Color="Yellow" Offset="0"/>
                    <GradientStop Color="Orange" Offset="0.2"  x:Name="Foo"/>
                    <GradientStop Color="Red" Offset="1"/>               
            </LinearGradientBrush>
        </Border.Background>
    <!-- put your windowcontent(grid etc.) here -->
    </Border>
</Window>
