12/23/2023 0 Comments Xamarin studio release notes![]() Performance of load, sort and filter improved for scenarios with a huge number of rows (Model-virtualization).Rows and Columns.DisableAnimations() allows performing changes in the model without being animated.C1PagedCollectionView, ISupportPaging, C1VirtualCollectionView, C1SequenceCollectionView, C1SelectCollectionView, C1SelectMan圜ollectionView, C1CacheCollectionView, C1EditableCollectionView, C1DelegateList and ISupportAsyncLoading, EntityFrameworkVirtualCollectionView added.With the cursor collection view you need to bring the pages in one at a time (and the activity indicator displays at the bottom).The trade off to using the new virtual collection view is that it needs to calculate the total count of items in the table, which can be an expensive database operation. The benefit of the virtual collection view is that when you scroll a list of items, you can go directly to the last item. This release introduces the EntityFrameworkVirtualCollectionView to join the EntityFrameworkCursorCollectionView.C1EditableCollectionView – with this collection view changes made to the collection are tracked locally and aren’t committed to the source immediately.C1SequenceCollectionView - this collection allows composing a range of collection into one sequentially to be exposed as a single collection.It can be used together with C1SelectCollectionView to avoid calling the selector repeatedly for the same item, and thus improve performance. C1CacheCollectionView - this collection keeps a reference to the items when they are accessed.C1SelectMan圜ollectionView - this is like C1SelectCollectionView, but every item of the original collection is converted to a range of items in the resulting collection.This collection is a transforming collection, like C1SortCollectionView or C1FilterCollectionView. C1PagedCollectionView - provides a paged collection view that supports the ISupportPaging interface that allows controls like C1DataPager to change the pages.This collection resolves the problem of synchronizing requests and avoiding duplicates. C1VirtualCollectionView - provides page-like data virtualization with a GetPageAsync() method that populates the collection view.SfCardLayout Bug fixes FB28784 - Android The SfCardLayout will no longer be thrown exception when setting the Visual as Default. Both of these data-providing and transforming collection views are newly added in 2019 v2 along with several others: Essential Studio for Xamarin.Forms Release Notes v19.3.0.44 OctoSfAccordion Bug fixes I342581 - UWP The NullReferenceException will no longer be thrown when navigating back from another page. For example, you can implement paged data virtualization by wrapping a C1VirtualCollectionView with a C1PagedCollectionView. ![]() The CollectionView for Xamarin is enhanced with virtualization features including several new collection views designed for specific scenarios.The viewer supports page navigation and text search.ĬollectionView for Xamarin Virtualization Enhancements ![]() Use the FlexViewer (beta) to display PDF files in your Xamarin.Forms, Xamarin.Android or Xamarin.iOS mobile apps.
