Update row when reordering ASP.Net GridView using jQuery Drag and Drop

Nevermind, I figured that out :

    Protected Sub gvLocations_RowDataBound(sender As Object, e As GridViewRowEventArgs)
        If e.Row.RowType = DataControlRowType.DataRow Then
            Dim myLabel As Label = CType(e.Row.FindControl("lblUp"), Label)
            Dim text As String = myLabel.Text
            If text = "" Then
                e.Row.BackColor = Nothing
            Else
                e.Row.BackColor = Drawing.Color.LightYellow
            End If
        End If
    End Sub
