A simple explanation of the GridView Control is needed?????

I am trying to use the ASP.Net GridView control and not having much luck figuring it out. I know it's suppose to be more simple than most but here I am struggling with it. All I want to do is take a SQL Query with 4 columns and populate a GridView. I want to do this dynamically in the VB.Net code-behind referencing each column. Anyone wanna take a shot at this easy request? I'm so pissed off with this because I can't find a straight-forward answer on the web.

Moved to the ASP.Net forum

Google a little. I think this has various examples on the web. If you can't find anything let us know what you are trying so far. I will see this tomorrow.
Goodnight.
