Why
TableViewalready supports incremental loading - its internal collection view forwardsHasMoreItemsandLoadMoreItemsAsyncto anyItemsSourceimplementingISupportIncrementalLoading- but this was undocumented, and the performance guide incorrectly stated the feature was unsupported. There was also no sample demonstrating it.What's changed
Sample app
IncrementalLoadingSource- anObservableCollection<ExampleModel>implementingISupportIncrementalLoadingthat simulates fetching pages from a remote service (750 ms delay, capped at 1,000 items).IncrementalLoadingPageusingSamplePresenter, withIncrementalLoadingTrigger/IncrementalLoadingThreshold/DataFetchSizeset on the TableView, an options panel showing loaded item count,HasMoreItemsstate, and an indeterminate progress bar while a page loads. XAML and C# source snippets included.MainWindow.Docs
docs/docs/incremental-loading.mdcovering how to implement an incremental source, the inheritedListViewloading properties, manual loading from code, and caveats (sorting/filtering/clipboard/export operate only on loaded items).performance.mdthat claimedISupportIncrementalLoadingwas not supported.
