Question

When I’m making a new Visual Studio Windows 8 Store Project (C#), I get dummy data if I start off With a SplitPage, however, if I’m adding new SplitPages to the Project, there’s no dummy data coming With it, and I just get a ton of errors if I try the code from the main SplitPage (the one created when I made the actual Project).

How can I get dummy data in the “new added” SplitPages, not only in the main Project file?

You can do it manually. You can use ExampleDataSource classes which you can find in any example.
Then in XAML code, when you describe CollectionViewSource in Page.Resources you usually bind data-source in way like:

        <CollectionViewSource
            x:Name="itemsViewSource"
            Source="{Binding YourDataSource}"/>

Here you use Source parameter to specify binding. Now use parameter d:Source. Namespace d is used for describing things, which will be used only in designer (that’s why it is d, I believe).

So try adding this parameter to your CollectionViewSource:

        d:Source="{Binding AllGroups, Source={d:DesignInstance Type=data:SampleDataSource, IsDesignTimeCreatable=True}}"

Assuming that SampleDataSource has property AllGroups and it is ObservableCollection, it should work.

Hope my answer helps anyone dealing with Win8 apps.
