LongListSelector不滾動

Question

我無法讓我的長列表選擇器正常工作。當列表比屏幕高時，長列表選擇器保持靜態，我無法滾動查看所有項目。

有什麼想法？

<phone:PivotItem Header="{Binding Path=LocalizedResources.ApplicationsHeader, Source={StaticResource LocalizedStrings}}" x:Name="applicationsPivotItem"> 
    <Grid x:Name="applications" Grid.Row="1"> 
     <phone:LongListSelector x:Name="MainLongListSelector" ItemsSource="{Binding Items}" SelectionChanged="MainLongListSelector_SelectionChanged"> 
      <phone:LongListSelector.ItemTemplate> 
       <DataTemplate> 
        <StackPanel> 
         <TextBlock Text="{Binding LineOne}" TextWrapping="Wrap" Style="{StaticResource PhoneTextExtraLargeStyle}"/> 
         <TextBlock Text="{Binding LineTwo}" TextWrapping="Wrap" Margin="12,-6,12,0" Style="{StaticResource PhoneTextSubtleStyle}"/> 
        </StackPanel> 
       </DataTemplate> 
      </phone:LongListSelector.ItemTemplate> 
     </phone:LongListSelector> 
    </Grid> 
</phone:PivotItem>

修復的電網

<Grid x:Name="applications" Grid.Row="1" Height="400"> 
...long list code... 
</Grid>

我也有類似的問題，即我的panoramaItem是高度定義如下：

  <phone:PanoramaItem> 
       <Grid> 
        <Grid.RowDefinitions> 
         <RowDefinition Height="Auto"/> 
        </Grid.RowDefinitions> 

        <phone:LongListSelector x:Name="SpeciesList" Grid.Row="0"> 
         <phone:LongListSelector.ItemTemplate> 
          <DataTemplate> 
           <StackPanel Margin="0,-6,0,12"> 
            <TextBlock Text="{Binding PrimaryName}"/> 
           </StackPanel> 
          </DataTemplate> 
         </phone:LongListSelector.ItemTemplate> 
        </phone:LongListSelector> 
       </Grid> 
      </phone:PanoramaItem> 

通過改變RowDefinition用*代替汽車，我的滾動問題已解決！如下所示。

    <Grid.RowDefinitions> 
         <RowDefinition Height="*"/> 
        </Grid.RowDefinitions>

我有與LongListSelector不滾動相同的問題。最後是在LongListSelector中設置的OpacityMask =「White」，導致問題as per this question

同樣根據Mattias，我沒有設置特定高度，只要將網格RowDefinition設置爲* 。
