So as development continues on iMoney I looked at implementing a ‘grouping’ feature for the debits and credits.
Enter the CollectionViewSource.
Now I wont lie it took a while to wrap the grey matter around it but after some research and wine I established this code.
I then feed the monthSummaryCollectionGrouped object into the CollectionViewSource source.
And in the XAML, I used VisualStateManager to ensure the app can work across devices.
