Sorting Gridview

[Will]

So I have a gridview with a column that has a drop down in that column.
What I want to do is resort the gridview which is originally sorted by
that column to be resorted based on what is selected in the drop down.
Anyone know a good tutorial I can follow that does this?

The gridview has template columns in it, one has a drop down control in
it, and when I change the number in that drop down I want the whole
gridview to be reordered by that number that is selected in the drop
down.....any leads on how to do it?
