problem with sqldatasource and data binding
- by Alexander
I am trying to pull out data from the table I had from the database according to the id which is passed from the URL. However I always get data from id= 1? Why? FYI I took this code directly from the ClubWebsite starter kit and copy and paste it to my project to make several changes, the ClubWebsite one worked fine.. but this one doesn't and can't find any reason why because they both looked exactly the same.
