First of all, I'm using VS2005. On random compiles, I'll get the following error: 'DataKeys' is not a member of 'gridView'. This makes no sense to me, since DataKeys is obviously a member of GridView. Intellisense thinks so, the internet thinks so, I think so. The line that's causing this issue is...
