# CollectionView — .NET MAUI `CollectionView` is the primary control for displaying scrollable lists and grids of data in .NET MAUI. It replaces `ListView` with better performance, flexible layouts, and no `ViewCell` requirement. ## When to Use - Displaying a scrollable list or grid of data items - Binding a collection of objects to a templated item layout - Adding selection (single or multiple), grouping, or pull-to-refresh - Implementing infinite scroll / incremental loading - Showing swipe actions on list items - Displaying an empty state when no data is available ## When Not to Use - Static layouts with a fixed number of items — use `Grid` or `StackLayout` directly - Map pin lists — use the `Microsoft.Maui.Controls.Maps` NuGet package - Table-based data entry forms — use standard form controls - Simple text-only lists with no interaction — consider `BindableLayout` on a `StackLayout` ## Scope Control — Answer Only What Was Asked This skill is a **reference you consult**, not a checklist you apply.

Do not append grouping, swipe actions, empty views, snap points, or performance tips that were not asked about. - **The user's existing code already works.** Do not rewrite working markup to match the examples here.
