How to use CollectionViewAdv ?

[maxima]

I wanted a sortable collection like CollectionViewSource in Silverlight and UWP doesn't have one. I found SF CollectionViewAdv. It has all the right params in the intellisense but the documentation doesn't give any meaningful details.

so I just wrote at best guess:

     dataView = new CollectionViewAdv(data);

     lst.ItemsSource = dataView;

and although the view created ok, on the second statement I got nullRef exception without any idea what happened.

Anyone uses it? whats the correct use? or is there another collection for that?

I need to write something like :

    dataView.SortDescriptions.Add(new SortDescription("SOMEPROP", ListSortDirection.Ascending));

Hi Volodymyr, 

Thank you for contact Syncfusion support. 

We are having Syncfusion.data.uwp for doing data operations needed for SfDataGrid. You can use it in your application if it suits your needs. As this is internal view of SfDataGrid, you can’t find the documentation for the same. Please find the getting started code snippet for doing sorting and grouping using QueryableCollection. 

QueryableCollectionView view = new QueryableCollectionView(viewM.Orders); 

             

view.SortDescriptions.Add(new SortDescription() { PropertyName = "OrderID", Direction= ListSortDirection.Descending }); 

 

view.GroupDescriptions.Add(new PropertyGroupDescription() { PropertyName = "OrderID" }); 

 

view.Filter = FilterRecord; 

 

//Get the ordered information when grouping not applied 

view.Records 

 

//Get the ordered information when grouping applied 

view.TopLevelGroup.DisplayElements 

 

//Get the groups list when 

view.TopLevelGroup.Groups 

We have attached the example application for you reference. You can able to download it from the below link.
