I followed this guide to create a grouped
Xamarin.Forms. Doing so, the following
Property is given which is bound as the
ItemSource of the
DevicesGrouped = new ObservableCollection<Grouping<string, Device>>(sorted);
Everything works just fine, including the grouping functionality.
To search (and thereby filter) the entries in the list, I have tried to implement this pattern:
this.ItemsSource = DevicesGrouped .Where (x => x.Name.ToLower () .Contains (filter.ToLower ()));
The problem is, that I do not have access to the properties of the
Device as the objects reside in
Groupings. I can only access the
Key of the
DevicesGrouped which, in this case, is a
Manufacturer, where I want to search for the
Name. The problem in searching for the
Key is also, that the
ListView scrolls to the position of the
Key and thus hides the elements in the
ListView behind the grouping header.
My question is thus, how would one access the properties of the
ObservableCollection which is Grouped?
I have tried keeping a List which I use when I filter, but doing so, the app crashes, since
Groupings are enabled on the
Thanks for the help in advance.
