使用一个大集合- Windows 8 DataGrid

我正在做一个Windows 8应用程序(c#/XAML)。其中一个要求是在DataGrid中加载一个单词集合，我们在这里使用Semantic Zoom选项。

当集合超过1500项时，应用程序挂起并给出以下错误:

+Exception{"没有足够的配额来处理此命令。(来自HRESULT: 0x80070718的异常)"}系统。除了

一些使用的代码:

_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;

这是XAML代码:

 <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>
