silverlight数据绑定 故事板

 

前台代码：

<navigation:Page x:Class="story.databind"
           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"
           mc:Ignorable="d"
           xmlns:navigation="clr-namespace:System.Windows.Controls;assembly=System.Windows.Controls.Navigation"
           d:DesignWidth="640" d:DesignHeight="480"
           Title="databind Page" Loaded="Page_Loaded">
    <UserControl.Resources>
        <Storyboard x:Name="sb">
            <DoubleAnimation Storyboard.TargetName="pb" Storyboard.TargetProperty="Value" From="0" To="200" AutoReverse="True" RepeatBehavior="Forever" Duration="0:0:3" ></DoubleAnimation>
        </Storyboard>
    </UserControl.Resources>
    <Grid x:Name="LayoutRoot" >
   
        <ProgressBar Height="15" HorizontalAlignment="Left" Margin="352,220,0" Name="pb" VerticalAlignment="Top" Width="200" Minimum="0" Maximum="200" />
        <TextBox Height="23" HorizontalAlignment="Left" Margin="352,118,0" Name="textBox1" VerticalAlignment="Top" Width="120"  DataContext="{Binding ElementName=pb}" Text="{Binding Value,Mode=TwoWay}" >
          
       </TextBox>
    </Grid>
</navigation:Page>

 

我们后台只需要写：

   private void Page_Loaded(object sender,RoutedEventArgs e)
        {
            sb.Begin();
        }

就OK了。
