grdiview selectedindex & selectedvalue

[katmagic]

I have the selectedindex of a gridview, but no value. How do I set the
selectedvalue of a gridview?

My scenario: I have 3 gridviews on a page, all of which use the same insert
record control. When the user inserts a record, everything works fine
because it is getting the selectedvalue of the gridview that is selected.
However once a record is inserted, the gridviews are rebound, but the
gv.SelectedIndex is saved from the gridview that the user selected. When a
user enters a second record, I have the SelectedIndex, but there is no
selectedvalue. So if I have the selectedindex, how do I get the
SelectedValue of that gridview. Hope that makes sense & thanks so much for
your help.
