copied!<p>DynamicResources unfortunately don't exist in Silverlight.</p> <p>Some people use Bindings.</p> <p>There's a sneaky way to simulate the experience within a single UserControl that you might want to try.</p> <p>All that's happening in the code below is that the Storyboard animates a single rectangle's Fill, which is then bound to the other Fill's in the UserControl by using Element binding. The source rectangle doesn't need to be visible for this to work.</p> <pre><code><UserControl x:Class="TestSilverlightStuff.MainPage" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" xmlns:local="clr-namespace:TestSilverlightStuff" mc:Ignorable="d" d:DesignHeight="300" d:DesignWidth="400"> <UserControl.Resources> <SolidColorBrush x:Key="Background" Color="Black" /> </UserControl.Resources> <Grid x:Name="LayoutRoot"> <VisualStateManager.VisualStateGroups> <VisualStateGroup x:Name="MyStates"> <VisualState x:Name="Normal"/> <VisualState x:Name="Red"> <Storyboard> <ColorAnimation Duration="0" To="Red" Storyboard.TargetProperty="(Shape.Fill).(SolidColorBrush.Color)" Storyboard.TargetName="trickyRectangle" d:IsOptimized="True"/> </Storyboard> </VisualState> </VisualStateGroup> </VisualStateManager.VisualStateGroups> <Rectangle Fill="Black" x:Name="trickyRectangle" Visibility="Collapsed" /> <Border Background="{Binding Fill, ElementName=trickyRectangle}" Width="100" Height="100" HorizontalAlignment="Left" VerticalAlignment="Top" BorderBrush="Red" BorderThickness="1"/> <Rectangle Fill="{Binding Fill, ElementName=trickyRectangle}" Width="100" Height="100" HorizontalAlignment="Right" VerticalAlignment="Bottom"/> <Button Content="Button" Height="57" HorizontalAlignment="Left" Margin="12,231,0,0" Name="button1" VerticalAlignment="Top" Width="153" Click="button1_Click" /> </Grid> </UserControl> </code></pre> <p>Here's the C# button click code:</p> <pre><code>private void button1_Click(object sender, System.Windows.RoutedEventArgs e) { VisualStateManager.GoToState(this, "Red", true); } </code></pre> <p>It's not as elegant as a DynamicResource, but it works in some cases. </p>
