Since v3.4.0
Event detail emitted when lazy child loading completes successfully.
Properties
Section titled “Properties”| Property | Type | Description |
|---|---|---|
key | string | Stable key of the node whose children are being fetched |
row | T | The parent row data |
depth | number | Depth level of the parent node (0 = root) |
childCount | number | Number of child rows received (0 when cancelled) |
cancelled? | boolean | true when the load was superseded before it settled: the node’s row was replaced by a new object for the same key (e.g. a ServerSide refetch after a sort/filter change or refresh()) and the replacement rendered, so the request was aborted and nothing was merged. If the node is still expanded and the new row’s children are lazy, they are requested again (a fresh tree-load-start). v3.9.2+ |
