使用大集合 - Windows 8 DataGrid

我正在使用Windows 8應用程序（C＃/ XAML）。其中一個要求是在DataGrid中加載一個單詞集合，我們在這裏使用語義縮放選項。使用大集合 - Windows 8 DataGrid

當收集具有小於約1500的項目的應用程序掛起更多，並給出該錯誤：

+異常{「沒有足夠的配額是可用來處理該命令（從HRESULT異常：0x80070718）。」}系統.Exception

所用的一些代碼：

_collection = _readDictionary.GetModeDetailsForModeDetails(modeId); 

var query = from item in _collection 
      orderby (item.WordName.ToLower()) 
      group item by item.WordName[0].ToString().ToUpper() into g 
      select new { GroupName = g.Key.ToString().ToUpper(), Items = g }; 

foreach (var g in query) 
{ 
    GroupInfoList<Words> info = new GroupInfoList<Words>(); 
    info.Key = g.GroupName; 

    foreach (var item in g.Items) 
    { 
    info.Add(item); 
    } 

    groups.Add(info); 
} 

bindGroupData.Source = groups; 
(semanticZoom.ZoomedOutView as ListViewBase).ItemsSource = bindGroupData.View.CollectionGroups;

，這是XAML代碼：

<SemanticZoom x:Name="semanticZoom" VerticalAlignment="Bottom" > 
     <SemanticZoom.ZoomedOutView> 
      <GridView ScrollViewer.IsHorizontalScrollChainingEnabled="False" VerticalAlignment="Top" HorizontalAlignment="Left"> 
       <GridView.ItemTemplate> 
        <DataTemplate> 
         <TextBlock Text="{Binding Group.Key}" FontFamily="Segoe UI Light" Foreground="Red" FontSize="24"/> 
        </DataTemplate> 
       </GridView.ItemTemplate> 
       <GridView.ItemsPanel> 
        <ItemsPanelTemplate> 
         <WrapGrid ItemWidth="75" ItemHeight="75" MaximumRowsOrColumns="5" VerticalChildrenAlignment="Center" /> 
        </ItemsPanelTemplate> 
       </GridView.ItemsPanel> 
       <GridView.ItemContainerStyle>

         <Setter Property="VerticalContentAlignment" Value="Center" /> 
        </Style> 
       </GridView.ItemContainerStyle> 
      </GridView> 
      </SemanticZoom.ZoomedOutView> 
     <SemanticZoom.ZoomedInView> 
      <GridView x:Name="GrdViewWord" SelectionMode="Multiple" ItemsSource="{Binding Source={StaticResource bindGroupData}}" ItemClick="GrdViewWord_ItemClick" SelectionChanged="GrdViewWord_SelectionChanged" Background="#FFE2E2E2" Height="396" VerticalAlignment="Top" > 
       <!-- ItemContainerStyle="{StaticResource GridViewItemStyle}" --> 
       <GridView.ItemsPanel> 
        <ItemsPanelTemplate> 
         <!--<WrapGrid Orientation="Vertical" Background="{Binding BG}"/>--> 
         <StackPanel Orientation="Horizontal" /> 
        </ItemsPanelTemplate> 
       </GridView.ItemsPanel> 

       <GridView.ItemTemplate> 
        <DataTemplate> 
         <StackPanel Orientation="Horizontal" Height="20" Width="75" > 
          <TextBlock Text="{Binding WordName}" Tag="{Binding WordID}" FontFamily="Segoe UI" FontSize="12" Margin="5,5,0,0" Foreground="Black" HorizontalAlignment="Left" Height="20" Padding="0"/> 
         </StackPanel> 
        </DataTemplate> 
       </GridView.ItemTemplate> 

       <GridView.GroupStyle> 
        <GroupStyle> 
         <GroupStyle.HeaderTemplate> 
          <DataTemplate> 
           <Grid Margin="10"> 
            <!--Background="{StaticResource ApplicationPageBackgroundThemeBrush}"--> 
            <TextBlock Text='{Binding Key}' FontSize="25" Foreground="Red" Margin="5" /> 
           </Grid> 
          </DataTemplate> 
         </GroupStyle.HeaderTemplate> 

         <GroupStyle.Panel> 
          <ItemsPanelTemplate> 
           <VariableSizedWrapGrid Orientation="Vertical" Height="300" /> 
          </ItemsPanelTemplate> 
         </GroupStyle.Panel> 
        </GroupStyle> 
       </GridView.GroupStyle> 
      </GridView> 
     </SemanticZoom.ZoomedInView> 
    </SemanticZoom>

任何人都可以請幫我解決這個問題嗎？
