I did some checking on here and in the sample app and found that there is a global.asax in the sample app that I don't have in my app.  Additionally, looks like that's where I am supposed to setup the data connection.

So, here are my questions...

Do I need a global.asax and what is it for? 

If it is necessary, should it have been added when I created the project? 

Lastly, if I add one, will that take care of my DataSourceKey error?

Thanks again for any help!
