    <p>I am trying to create a grid containing elements such as</p> <pre><code>| 1 | 4 | 7 | | 2 | 5 | 8 | ===&gt; extend | 3 | 6 | 9 | </code></pre> <p>Since the data is very large, I need to use UI virtualization and what I see in most example is the VirtualizingStackPanel</p> <p>Here is how I have setup my Gridview in XAML . The problem is that the following code creates a horizontal row of single element (which makes sense given it is just a stack panel). </p> <pre><code>| 1 | 2 | 3 | 4 | ..... &lt;GridView x:Name="itemGridView" AutomationProperties.AutomationId="ItemsGridView" AutomationProperties.Name="Items" TabIndex="1" Grid.RowSpan="3" Padding="116,136,116,46" ItemsSource="{Binding Source={StaticResource itemsViewSource}}" ItemTemplateSelector="{StaticResource CellStyleSelector}" ItemClick="ItemView_ItemClick" IsItemClickEnabled="True" SelectionMode="Extended" SelectionChanged="ItemView_SelectionChanged" IsSwipeEnabled="true"&gt; &lt;GridView.ItemsPanel&gt; &lt;ItemsPanelTemplate&gt; &lt;VirtualizingStackPanel Orientation="Horizontal"/&gt; &lt;/ItemsPanelTemplate&gt; &lt;/GridView.ItemsPanel&gt; &lt;/GridView&gt; </code></pre> <p>How would one go about making it display a grid that extends horizontally using virtualizingstackpanel? I have no groups in my data so all the examples that show virtualizingstackpanel show this ? I am completely new at Windows Store app dev (mostly have been on iOS and Android ) so would appreciate any code sample or resources.</p> <p>Thank you</p>

    1. COIt looks like the default ItemsPanel of GridView itself is virtualizing. So this question itself is invalid. It looks like Virtualization can get broken due to other conditions (such as grouping etc)

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
