Silverlight多个xap之间导航 silverlight整站程序动态加载xap包
XAML代码：
1 <Border Name="Frame" Grid.Column="1" Style="{StaticResource ContentBorderStyle}">
2 <Grid Grid.Column="1" Name="gridFrame">
3
4 </Grid>
5 </Border>
后台代码:
1 private void LoadSolutionManagement()
2 {
3 WebClient Appclient = new WebClient();
4 Appclient.OpenReadAsync(new Uri("UI.xap", UriKind.Relative));
5 Appclient.OpenReadCompleted += new OpenReadCompletedEventHandler(Appclient_OpenReadCompleted);
