Hi Syed,
I meant about your local variable (isPaid)
If IsPaid is "not NULL" then the t.IsPaid == null cannot be true...
Could you please try this one below?
return dc.TicketInfos.Where(t => ((locationId != null&& t.LocationId == locationId) || t.LocationId == null) && ((issuerId != null&& t.IssuerId == issuerId) || t.IssuerId == null) && (isPaid == null || t.IsPaid == isPaid)).ToList();
Regards, Peter
