Problemas con GridView

[NicroX]

Aquaventus: en la grilla si tome en cuenta el = y tengo mas valores solo quiero editar uno que esta en el medio.-

lucord este es el codigo completo del GridView1_RowUpdating y cargo la grilla con este

codigo: cargagrid("V_MemoriasTecnicas", "select * from V_MemoriasTecnicas where num_mt=" & cod_memtec.Text, GridView1)
y enlazo con los nombres de los campos de la BD y eso los muestra, lo raro que en visual .Net 2008 funionaba lo mas bien, migre a 2010 y dejo de funcionar

Código:

If GridView1.SelectedIndex >= 0 Then
            Dim dt = CType(Session("TaskTable"), DataTable)
            Dim row = GridView1.Rows(e.RowIndex)

            Dim a As String = row.Cells(1).Text
            cam = GridView1.SelectedRow.Cells(5).Text

            If cod_memtec.Text <> "" Then
                cod = devuelve_codigo("SELECT * FROM Tab_MemoriaTecnicaDet where id_mtdet=" & GridView1.SelectedRow.Cells(1).Text, "Tab_MemoriaTecnicaDet", "id_mtdet")
