我真的與wp8列表框滾動混淆。用下面的簡單代碼我滾動到選定的索引(項目),但它不起作用。如何滾動到列表框中的選定項目
lsbReadingChapter.SelectionChanged -= lsbReadingChapter_SelectionChanged;
_lastAyaSelectedIndex = startingAya;
lsbReadingChapter.ItemsSource = null;
lsbReadingChapter.ItemsSource = ds.getArabicTextWithTranslation(currentChapter);
lsbReadingChapter.SelectedIndex = startingAya;
lsbReadingChapter.UpdateLayout();
lsbReadingChapter.ScrollIntoView(lsbReadingChapter.SelectedItem);
lsbReadingChapter.SelectionChanged += lsbReadingChapter_SelectionChanged;
selectedIndex總是大於零,但列表框顯示列表中的第一項並且不滾動。
這是我的XAML
ListBox x:Name="lsbReadingChapter" HorizontalAlignment="Stretch" Grid.Row="1" ScrollViewer.VerticalScrollBarVisibility="Visible" Width="480" SelectionChanged="lsbReadingChapter_SelectionChanged" Loaded="lsbReadingChapter_Loaded">
<ListBox.ItemTemplate>
<DataTemplate>
<StackPanel HorizontalAlignment="Stretch" Width="480" Orientation="Vertical" Background="{Binding Converter={StaticResource AlternateRowConverter}}" >
<TextBlock Foreground="Black" Padding="20,0,30,0" TextWrapping="Wrap" HorizontalAlignment="{Binding HAlignment}" FontSize="{Binding ArabicFontSize}">
<Run Text="{Binding Aya}"/>
<Run Text="{Binding AyaID, StringFormat=﴿\{0\}﴾}" Foreground="Blue" FontSize="30"/>
</TextBlock>
<TextBlock Padding="20,0,30,0" Text="{Binding AyaTranslation}" Foreground="Black" FontSize="{Binding TranslationFontSize}" TextWrapping="Wrap" HorizontalAlignment="{Binding HAlignment}"/>
</StackPanel>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
我不知道爲什麼它不滾動到所選擇的指數?
謝謝!
謝謝。正如你可以使用我的代碼,但它不起作用。 – ARH

我調試過,所選索引已更改,但滾動不起作用。 – ARH
