All about the Microsoft way

I'm trying to figure out the best way to re-execute the sql to update the data in a dataSet based on a change in what's selected in a asp:RadioButtonList. I can see what has changed and am able to update the selectCommand for the dataSet object. I just can't find what I need to do to make it actually execute the sql and update the page with the new data.

Databinding was the key. I asked a friend and found an answer to this question very quickly. It seems many times that the simple things take some time to become accustomed to.
