I posted the other day regarding a solution i needed to design, im new to development an asp,net and built a local post office search tool using asp.net 2. vb in visual studio, using an sql express mdf database(this means the database is transferable with the solution even if the server doesnt have sql server on it) The app works fine, users can search, admins can edit data, insert and delete. The site also has membership and role management.
My problem is that i needed to be able to have a user browse a csv file and upload it into a datagrid and then the database. ive got the following but recieve an error when running it.
