Performance Issues loading large data set into c# GridView

Question

Ok,

been testing relatively small data sets into my GridView, and all has worked fine. However, i\'ve now moved into proper UAT and have tried to load 17,000 records

Answer 1

Really, loading a 17k record once is not useful even user can not see the whole 17k records at once. I would suggest you to use pagination along with DataTable.Merge function which helps to load records in chunks and append the new fetched data into previous one. I just did a quick test and found a solution. Give this a try.
