Clear the list before you fill it each time i.e. datalist.clear(); something like that

I need to allow multiple Selection so I can't clear the the list before fill it each time, otherwise I can use just DataSource and bind the data to it. I need other Solution :) Regards

Run a query to check if the values already exist in the other list, if so dont add, if not add. Try something like that
