Want to fix four items per row in a gridview in Windows Phone 8.1 app. I am using data binding.

Question

No of items in a row of grid varies for different resolution WP devices. How can it be fix to say 4 items per row. Here is xaml:
<DataTemplate x:Key="DataTemplate1">
<Grid Margin="8,0">
<Grid.RowDefinitions>
<RowDefinition Height="Auto"/>
<RowDefinition Height="Auto"/>
</Grid.RowDefinitions>
<Border Background="{ThemeResource ListViewItemPlaceholderBackgroundThemeBrush}" Margin="0,9.5,0,0">
<Image x:Name="image" Height="100" Width="100" Source="{Binding ImageName}" >
</Image>
</Border>
<TextBlock Grid.Row="1" Text="{Binding Name}" />
</Grid>
</DataTemplate>
<Grid>
<GridView ItemTemplate="{StaticResource DataTemplate1}" ItemsSource="{Binding Data1}" HorizontalAlignment="Center" >
</GridView>
</Grid>

You could change the GridView's size to datatemplate size * 4 (and allow for any padding). This would have the side-effect of making the GridView a different size on different screens though (e.g. on a higher-resolution screen the grid will be smaller, but
will have the correct number of rows).
I'm not sure if it's possible, but see if you can adjust the datatemplate's size at runtime to be 1/4 the gridview size. This will scale nicely if it works.
