Methods

ClearPinnedRows()

ClearPinnedRows(): any

ClearPinnedRowsAsync()

Called to clear all pinned rows.

ClearPinnedRowsAsync(): any

Clone()

Clone(): any

CloneAsync()

Clones this data source instance, copying the summary, grouping, filter and sorting settings into the new instance.

CloneAsync(): any

FlushAutoRefresh()

FlushAutoRefresh(): any

FlushAutoRefreshAsync()

Called to make sure a queued refresh of the data source has been applied before continuing. Should only be needed if you are trying to synchronously examine the results of changing settings on the data source. Note, for a virtual data source, the data source itself may be waiting for other synchronous requests to actualize data. This call will not wait for those, but will only make sure the appropriate requests are in flight from the settings changes

FlushAutoRefreshAsync(): any
