Gridview update with sqldatasource and dropdown

[Will]

I have searched and solutions that I have found are not working, I have
a datagrid that will be updating a mysql db. Now I have a drop down
that has a static collection but is dynamically selected to a selected
value thats in the database. I click the edit button in the gridview
and the drop down shows up fine, I pick a number in the drop down and
hit update it says at that new number but the database never
updates.....help anyone know why? Is there anyway to print the
updatecommand to the screen to show what values are going to the
database?
