well using dynamic linq extension library iqueryable type of collection. collection of iqueryable. , apply cluase on when enumberate throws exception of null reference. please @ below stack trace.

iqueryable<t> returndata = source.where(advancesearchparameter.advancesearchtext, advancesearchparameter.advancesearchvalue);

where extension method come dynamic extention library.

here source object of type iqueryable<t> , getting error when returndata gets executed(enumerate).
