How to enable lefto-right scrolling of GridView in Windows Phone 8.1 WinRT?

gridview, windows-phone-8.1, winrt-xaml

Solution

GridView needs to have it enabled. So, in the GridView, you also need to set the HorizontalScrollMode property.

<GridView x:Name="GridView1" Margin="0,9.5,0,0"
          ItemsSource="{Binding Items}"
          SelectionMode="None"
          IsItemClickEnabled="True"
          ItemClick="ItemView_ItemClick"
          ScrollViewer.VerticalScrollBarVisibility="Visible"  
          ScrollViewer.HorizontalScrollBarVisibility="Visible"
          ScrollViewer.HorizontalScrollMode="Auto">

....

</GridView>

Problem

I am trying to change the orientation of GridView from the default up-down to left-right. Only I cannot get manual scolling to function even though calling ScrollIntoView from code behind works just fine. Here are details for my test project. 1) File >> New Project >> Hub App (Windows Phone) 2) HubPage.xaml (Hub control removed and replaced with just a GridView) ``` <Grid x:Name="LayoutRoot" DataContext="{Binding Groups[5]}"> <GridView x:Name="GridView1" Margin="0,9.5,0,0" ItemsSource="{Binding Items}" SelectionMode="None" IsItemClickEnabled="True" ItemClick="ItemView_ItemClick" ScrollViewer.VerticalScrollBarVisibility="Visible" ScrollViewer.HorizontalScrollBarVisibility="Visible"> <GridView.ItemsPanel> <ItemsPanelTemplate> <ItemsWrapGrid Orientation="Vertical" ScrollViewer.HorizontalScrollBarVisibility="Visible" ScrollViewer.VerticalScrollBarVisibility="Visible"/> </ItemsPanelTemplate> </GridView.ItemsPanel> <GridView.ItemTemplate> <DataTemplate> <Grid Margin="0,0,9.5,9.5" Background="{ThemeResource ListViewItemPlaceholderBackgroundThemeBrush}"> <Image Source="{Binding ImagePath}" Stretch="UniformToFill" AutomationProperties.Name="{Binding Title}" Height="200" Width="200"/> <TextBlock Text="{Binding Title}" VerticalAlignment="Bottom" Margin="9.5,0,0,6.5" Style="{ThemeResource BaseTextBlockStyle}"/> </Grid> </DataTemplate> </GridView.ItemTemplate> </GridView> </Grid> ``` 3) HubPage.xaml.vb (only change in this click handler) ``` Private Sub ItemView_ItemClick(sender As Object, e As ItemClickEventArgs) GridView1.ScrollIntoView(GridView1.Items.Last) End Sub ``` What am I missing here?
