Refreshes destdataset whenever the source fieldname field (on the datasource dataset) changes value, by setting the destdataset parameter named paramname to it. fieldname must be a field that actually fires data change events — a fkcalculated field does not, so it can not be used to trigger the link. To set more than one destination parameter from a single source field change, do it in onsetparam of one link rather than adding one tfieldparamlink per parameter, to avoid refreshing destdataset once per parameter.
