How can I progamatically change the view port size in the foundset property ? . What is the place I can do it ? . How can I do it . Please provide some suggestions.
You can ask for a change in viewPort size from component's (client) js using loadRecordsAsync, loadExtraRecordsAsync or loadLessRecordsAsync. Those methods are available on the value of the foundset property in browser - the same one that contains the viewport as well.
