Im having Listview which shows 185 columns and 15 rows. For showing 185 columns with 15 rows, windows store app takes some time or UI gets freezes. below is the code Im using for showing data
<ListView x:Name="outerlstView"
Height="650"
Margin="2,24,10,10" Grid.Row="1"
Grid.Column="1" BorderThickness="1" HorizontalAlignment="Stretch" VerticalAlignment="Stretch"
ItemsSource="{Binding Data,Mode=TwoWay,UpdateSourceTrigger=PropertyChanged}"
ScrollViewer.HorizontalScrollBarVisibility="Visible"
ScrollViewer.HorizontalScrollMode="Enabled" ScrollViewer.VerticalScrollBarVisibility="Auto"
SelectionMode="None" ShowsScrollingPlaceholders="True" IsZoomedInView="False"
IsSwipeEnabled="False" IsItemClickEnabled="False"
ItemContainerStyle="{StaticResource LvItemStyle}"
<ListView.ItemsPanel>
<ItemsPanelTemplate>
<StackPanel

</ItemsPanelTemplate>
</ListView.ItemsPanel>
<ListView.ItemTemplate>
<DataTemplate>
<ListView SelectionMode="None" IsZoomedInView="False" IsHoldingEnabled="False"

the above code has listview inside it another listview. when i try to load list<list> to listview it takes too much of time. Some time app crashes when i load 100 rows with 185 columns.
I tried to replace Itemtemplate stye control to Itemstackpanel performance is good. data is loaded and shown on screen faster but i dont see Horizontal scroll
Previous Code
<ListView.ItemsPanel>
<ItemsPanelTemplate>
<StackPanel
Orientation="Vertical" VirtualizingStackPanel.VirtualizationMode="Standard"/>
</ItemsPanelTemplate>
</ListView.ItemsPanel>
<ListView.ItemTemplate>
when i modify to `<ListView.ItemsPanel>
<ItemsPanelTemplate>
<ItemsStackPanel Margin="0,0,0,0" Width="Auto" Orientation="Horizontal" Height="35" VirtualizingStackPanel.VirtualizationMode="Standard"/>
</ItemsPanelTemplate>
</ListView.ItemsPanel>`
i dont see horizontal scrollbar enabled. Can any1 suggest me how to enable Horizontal scroll bar enabled by default to Itemstackpanel in windows store apps.Looks like it is bug with this control or there work arounds to ItemsStackpanel with Horizontal Scrollbar.
