API Reference > imodeljs-frontend > Tiles > TileRequestChannel > onNoContent onNoContent Method Invoked when Tile.requestContent returns undefined. Return true if the request can be retried, e.g., via different channel. If so, the tile will remain marked as "not loaded" and, if re-selected for display, a new TileRequest will be enqueued for it. Otherwise, the tile will be marked as "failed to load" and no further requests will be made for its content. The default implementation always returns false. onNoContent(_request: TileRequest): boolean Parameter Type Description _request TileRequest Returns - boolean Defined in core/frontend/src/tile/TileRequestChannel.ts Line 239 Last Updated: 12 June, 2024
