To add to the Profiler suggestion, you can also capture this information using Extended Events.  Below is a script example to capture RPC and batch completed events.  This can be done from the SSMS Object Explorer as well:
--create ExtendedEvent session
CREATE EVENT SESSION [ParameterTrace] ON SERVER
ADD EVENT sqlserver.rpc_completed(
ACTION(sqlserver.sql_text)),
ADD EVENT sqlserver.sql_batch_completed(
ACTION(sqlserver.sql_text))
ADD TARGET package0.event_file(SET filename=N'C:\Temp\ParameterTrace.xel')
WITH (MAX_MEMORY=4096 KB,EVENT_RETENTION_MODE=ALLOW_SINGLE_EVENT_LOSS,MAX_DISPATCH_LATENCY=30 SECONDS,MAX_EVENT_SIZE=0 KB,MEMORY_PARTITION_MODE=NONE,TRACK_CAUSALITY=OFF,STARTUP_STATE=OFF)
GO
--start session
ALTER EVENT SESSION [ParameterTrace] ON SERVER
STATE = START;
GO
--stop session
ALTER EVENT SESSION [ParameterTrace] ON SERVER
STATE = STOP;
--query trace data
SELECT CAST(event_data AS XML) AS event_data
FROM sys.fn_xe_file_target_read_file(N'C:\temp\ParameterTrace*', default, default, default);
