ListPresenter and CollectionViewSource

Hello,

Here is the explanation. ListBox or UXListBox should work with CVS since it derived from ItemsControl. There seems a built-in mechanism to pass the View property from CVS which type ICollectionView for the items processing.

CSV is derived from Dependency Object and does not implement any IEnumerable or ICollectionView

publicclass CollectionViewSource : DependencyObject, ISupportInitialize

For this matter, ListPresenter will not work.

ListPresenter is not derieved from ItemsControl. When it first release it does not even support ICollectionView, The ICollectionView support was added after release when to support Domain Data Source.

Our ListPresenter can do sorting and filtering. You can see our ClientUISample/DataPresenter.
Attached screenshot would show the ilustration about our filtering and sorting.

Since our List/Grid presenter would be obsolete in the future, I suggest you to use UXGridView when it has released.

Handy

Thanks for your answer.

I don't really understand why the ListPresenter doesn't support the CollectionViewSource as the View property implement the IEnumerable interface. I though that was the only need of the ItemsSource ... Am I wrong ?

Is there a workwaround to be able to sort or filter the elements in a ListPresenter without using a CollectionViewSource ?

Should we avoid to use the List/GridPresenter components to avoid futur problems ?

Hello Sebastian,

Unfortunately, ListPresenter does not support CollectionView Source. We glad that you kept following our latest product. We will release our rich UXGridView in the short time. You can see more information in this link.

Hi,

When I bind my ListPresenter to a CollectionViewSource, the "Loading" indicator on the bottom of the grid never change to "Ready" (I have only 3 records in my DB). The grid stay empty.

On some computer, we can get an exception whenever we tried to populate the ObservableCollection source of the View .

If I change the ListPresenter by a ListBox all is working fine.

So is it possible to bind a ListPresenter ItemsSource to a CollectionViewSource ?

I read on your blog you are working on a "great" grid, does it mean the ListPresenter will be obsolete ?

Any input on when the ClientUI 2011 R1 will be available ? :)

Regards,

Sebastien
