I don’t see how this is possible, but I really, really hate to run my query an extra time just to get the record count so I can build a pager. When I say a “pager” I simply mean the common gizmo with a link for each 10 records for example.
Assuming you are building a query in the selecting event, the best you could do is construct the full query, get and save the count, then take or skip it into the e.result.
And by best I mean, the easiest read code from a single query, rather than two. You’ll still be running two separate evaluations on the database though. Use query analyser to see if the statements are a ‘Select Count’ then a ‘Select take’ or a dirty big select pared down by LINQ after the retrieve. I think LINQ does the former.
