Clearing previous results in a grid on click of a search button

Set the batchsize to 0 to not retrieve any data, a!save(local!TestGridPaging.batchSize, 0). Also, to clear data from the datasubset, try this a!save(<DATASUBSET VARIABLE>, null)

I tried making batchsize as 0 and it gave me an error --> An error occurred while executing a save: java.lang.IllegalArgumentException: Invalid index: Cannot index property 'batchSize' into type GridSelection

Also, I already tried a!save(<DATASUBSET VARIABLE>, null) as above and it too gave me an error
Expression evaluation error in rule 'TestGridClearance' at function 'todatasubset' [line 161]: Error evaluating function 'todatasubset' : An invalid start index of 0 was passed in. Start indices must be greater or equal to 1.

--> An error occurred while executing a save: java.lang.IllegalArgumentException: Invalid index: Cannot index property 'batchSize' into type GridSelection

If TestGridPaging is GridSelection type then set batchsize like this: a!save(local!TestGridPaging.pagingInfo.batchSize, 0)

--> a!save(<DATASUBSET VARIABLE>, null)
Try setting the data part of the datasubset to null: a!save(<DATASUBSET VARIABLE>.data, null)
