2、自定义 Silverlight 程序的启动界面,并显示加载进度
启动界面的 xaml 文件
SplashScreen.xaml
启动界面的 xaml 文件
SplashScreen.xaml
<Grid xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Background="Bisque"
>
<StackPanel Orientation="Horizontal" HorizontalAlignment="Center" VerticalAlignment="Center">
<TextBlock Text="Loading" Margin="3" />
<TextBlock x:Name="percent" Text="0%" Margin="3" />
</StackPanel>
</Grid>
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Background="Bisque"
>
<StackPanel Orientation="Horizontal" HorizontalAlignment="Center" VerticalAlignment="Center">
<TextBlock Text="Loading" Margin="3" />
<TextBlock x:Name="percent" Text="0%" Margin="3" />
</StackPanel>
</Grid>
Silverlight 程序全部加载完成前,显示启动界面并显示加载进度
