GridView

GridView is a user interface component that presents a collection of items in a two-dimensional grid. It is used to display multiple items at once and to allow users to scroll through them. The exact API and behavior depend on the framework, but the core idea is a grid-based layout driven by a data source and an item template.

In Android, GridView is a view that arranges items in a scrollable grid. It uses an Adapter to provide data and item views, with a layout defined for each item. Developers typically handle item clicks, and the component can be replaced by RecyclerView in modern apps.

In WPF, GridView is a view mode for ListView that renders data in a table-like grid. Columns are defined by GridViewColumn, and items are bound to data sources. It supports sorting, templating, and flexible column sizing, but does not control general item layout beyond the grid.

ASP.NET GridView is a Web Forms server control that renders data in an HTML table. It provides built-in paging, sorting, editing, and templated rendering. While convenient for rapid data display, it can introduce postback overhead on large datasets.

Flutter's GridView is a scrollable grid of widgets. It uses a gridDelegate to determine tile size and arrangement and can build items on demand for performance. GridView supports various constructors, including fixed, extent, and builder modes, and works with Flutter's scrolling model.

Across implementations, GridView elements typically share scrolling, item templates, and data binding. Performance considerations include virtualization and lazy loading. The term "grid view" may refer to different control types across platforms; developers should consult the specific framework documentation for layout rules and limitations.
