TreeLoadChildrenParams

Since v3.4.0

Parameters passed to TreeConfig.loadChildren when a node whose children are not yet loaded is expanded.

Properties

Property	Type	Description
row	T	The parent row whose children are being fetched.
key	string	Stable key of the parent node (same value as FlattenedTreeRow.key).
depth	number	Depth of the parent node (0 = root).
signal	AbortSignal	Cancellation signal. Aborted when the plugin detaches or the grid disconnects. Pass it to fetch(url, { signal }). Implementations that ignore it keep working — the superseded request simply completes on the wire and its result is discarded.
