silverlight里的FindName的问题

Question

xaml： <Grid x:Name="LayoutRoot" Background="White"> <sdk:TabControl Height="100" HorizontalAlignment="Left" Margin="72,136,0,0" Name="tabControl1" VerticalAlignment="Top" Width="200"> <sdk:TabItem Header="tabItem1" Name="tabItem1"> <Grid /> </sdk:TabItem> </sdk:TabControl> <Button Content="Button" Height="23" HorizontalAlignment="Left" Margin="118,44,0,0" Name="button1" VerticalAlignment="Top" Width="75" Click="button1_Click" /> </Grid> code behind: public MainPage() { InitializeComponent(); TabItem ti = new TabItem(); tabControl1.Items.Add(ti); Grid g1 = new Grid(); g1.Name = "g1"; ti.Content = g1; Grid g2 = new Grid(); g2.Name = "g2"; g1.Children.Add(g2); object o1 = FindName("g1"); object o2 = FindName("g2"); } private void button1_Click(object sender, RoutedEventArgs e) { TabItem ti = new TabItem(); tabControl1.Items.Add(ti); Grid g3 = new Grid(); g3.Name = "g3"; ti.Content = g3; Grid g4 = new Grid(); g4.Name = "g4"; g3.Children.Add(g4); object o1 = FindName("g3"); object o2 = FindName("g4"); } 最后一个g4始终找不到，不知为何，本人初学silverlight，很多不懂，希望高手们能不吝赐教

我来赐教啦~

把tabControl1.Items.Add(ti);
移动到g3.Children.Add(g4);
下面，原因还没研究
