With a complex objects list this is difficult. I would suggest doing it server side.
If the lists contained numerical or string items you could rely on sorting to make your iteration process shorter.

What's the best practice when you have to compare two large lists? My main list is 9000 objects long. I have to compare this to another list which might have 4000 objects in it. Right now I'm doing it the WRONG way. For each row in the Main list i iterate through every item in the 4000 objects. As soon as I hit a match I return a true and that exits the iteration. This is still a very slow process. Both lists are dynamic. Any ideas on the right way to do this? Thanks, Nate
