I am creating a custom poll webpart using the following two lists:
1) QuestionList : Stores questions of poll (QuestionId,QuestionDate,Votes,TakenBy)
2) OptionsList: Stores option pertaining to a particular question (OptionId, Question(LookUp), Votes)
I have implemented the functionality. But my concern here is when multiple users try to submit their votes I am not able to achieve concurrency.
I using Sharepoint Web Services to achieve the functionality.
Can some one please throw some light on the issue?
