Grid interactions

Interaction configuration is fixed for the lifetime of a GridRuntime. The configuration separates four kinds of state:

• keyboard focus identifies the active cell or row cursor;
• cell selection identifies a rectangular copy or editing range;
• active-row context identifies one current row across the Grid; and
• row selection identifies operation targets.

Choose the reference that matches the coding task:

• Interaction configuration and presets for cell-grid versus row-list behavior, keyboard semantics, cell ranges, and the exported presets.
• Active rows and row activation for master-detail context and repeatable Enter, click, or double-click actions.
• Row selection for single, range, or multi-row operation targets, subscriptions, and selection chrome.

Other interaction surfaces live with their owning APIs:

• GridRuntime owns cross-path row operation targets.
• Advanced Grid composition owns imperative cursor and controller access.
• Grid DOM state contract owns public interaction-state attributes.
