</Columns>
</asp:GridView>
<br />
</div>
My code behind look like this. not sure what I am missing. I can't seem to get the values from the row. I have tried everything, DirectCast, FindControl.
Protected Sub OnRowUpdating(ByVal sender As Object, ByVal e As GridViewUpdateEventArgs)
Dim updVid As New VidInformation
Dim updVidRecord As New vidController
Dim row = gvVideos.Rows(e.RowIndex)
updVid.customerId = row.Cells(1).Text.ToString
gvVideos.EditIndex = -1
gvVideos.DataSource = updVidRecord.UpdateVidRecord(updVid)
bindGridview()
End Sub

Converting series of helpful comments to an answer
The correct way to get new values posted to edited GridView row is to use NewValues property of the even args object:
Protected Sub OnRowUpdating(ByVal sender As Object, ByVal e As GridViewUpdateEventArgs)
...
Dim updVid As New VidInformation
updVid.customerId = e.NewValues("customerId")
...
End Sub
As to why initial approach did not work. Important thing to realize is that GridView row in question was in edit mode during the previous load of the page. During the post back which edit button triggered new values are posted to the server, but the row is no longer in edit mode, so there are no more edit controls to be found in this row. Thus the method described above is the only by-design way to obtain new values for the row.
