Something like this would help.
Make a listpicker like this in your xaml.
<toolkit:ListPicker Name="lstCars" VerticalAlignment="Top" Width="220" >
<toolkit:ListPicker.ItemTemplate >
<DataTemplate >
<TextBlock Text="{Binding PropertyName}"/>
</DataTemplate>
</toolkit:ListPicker.ItemTemplate>
<toolkit:ListPicker.FullModeItemTemplate>
<DataTemplate >
<TextBlock Text="{Binding PropertyName}" FontSize="28"/>
</DataTemplate>
</toolkit:ListPicker.FullModeItemTemplate>
</toolkit:ListPicker>
an assign the list as an itemsource to the listpicker in c# like
lstCars.ItemSource=Your List;
