In order to get extended data of a request you should use Request API

SCN_LOAD_DATA pld = ...

HREQUEST rid = pld->requestId;

rapi()->RequestGetNumberOfParameters(rid,...);
rapi()->RequestGetNthParameterName(rid,...);
rapi()->RequestGetNthParameterValue(rid,...);

Another option is to handle and consume FORM_SUBMIT event.
Its BEHAVIOR_EVENT_PARAMS::data will contain name/value map of submitting parameters.
If you consume the event then no SC_LOAD_DATA request is generated.
