Set WebPopup value in Web 2.0

So I was setting the value of my WebPopups using:

self.GradePopup.Text = StudentRS.Column("Grade").StringValue

This no longer works. Looking at what should be replaced, I was hoping to change .text to .value and have it work (since that works fine with my textboxes) but apparently that’s not a property in WebPopups.

So how can I set that value?

Should I be reworking the whole thing for Web 2.0?

Edit: I need to figure out how to use binding, don’t I?

You should be setting the SelectedListIndex that matches the item you are trying to select.
