I have a grid that uses a LinqDataSource. The LinqDataSource uses the event Selecting to fill out the data retrieved. All works fine except that even though I am using a RadAjaxManager the grid still "blinks" when I use the paging controls instead of how the 300,000 row Telerik demo works. Will I not be able to accomplish that with the way I am doing it? My Linq query is a join. I have attached the code I use. If anyone has any tips, please let me know. I like the way the demo handles the postbacks.
