Perofrmance Issue when processing large number of records in a PageList
Hi, I am processing almost 3000 records via excel upload. In post processing, I have to perform some validation (I have to make sure that combination of 3 properties should be unique) for which I am using IsInPageListWhen function. But the problem is because of the large number of records, I am having performance issue since first I am looping on those 3000 records and each row's data I am validating again using function in the entire PageList which is giving me performance issues.
Appreciate any help to resolve the issue. Thanks
