Mar 16, 2011On my webpage, jobs.aspx, I have a gridview which is populated from my database. I would like it so that when a row in the gridview is clicked, the ID of the row from my database can then be passed through as a query string to a second webpage, details.aspx, where more information about what was clicked on will be displayed.
I'm confident about being able to pass the query string, I just need help with getting the corresponding row's data ID from my database and making the gridview click-able, which will be the interaction which specifies which ID to be retrieved.
