Ajout Item dans DDL

Bonjour,

Voilà je souhaiterai ajouter un Itel "Add a new Macro Brick" en début de DDL.
Pour cela je dispose d'un tableau avec un bouton "Update". Quand je clique dessus, une des colonnes pour la ligne cliquée se met en DDL.

Voilà ce que je fais (et qui ne fonctionne pas!):
-----------------------------------------------------------------------------
Protected Sub MappingList_RowUpdating(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewUpdateEventArgs) Handles MappingList.RowUpdating

        Dim AddMacro As ListItem
        AddMacro.Value = 0
        AddMacro.Text = "Add a new macro-brick"

        CType(MappingList.FindControl("ReferenceList"), DropDownList).Items.Insert(0, AddMacro)

End Sub
-----------------------------------------------------------------------

et voilà le code ASP:

-------------------------------------------------------------------------
<asp:GridView ID="MappingList" runat="server" AllowPaging="True" AutoGenerateColumns="False"
        DataSourceID="MappingListDB" DataKeyNames="NAT,SRCKEY"
        PagerSettings-Mode="NumericFirstLast"
        PagerSettings-PageButtonCount='<%$ AppSettings:GridViewPageButtonCount %>'
        PageSize='<%$ AppSettings:GridViewPageSize %>'
        AllowSorting="True">
        <Columns>
            <asp:CommandField ShowEditButton="True" />            
            <asp:TemplateField HeaderText="RegExtSales Brick"  SortExpression="SRCLAB">
                <ItemTemplate>
                    <%# Eval("SRCLAB")%> -  <%#Eval("SRCKEY")%>
                </ItemTemplate>
             </asp:TemplateField>
            <asp:TemplateField HeaderText="Macro Brick" SortExpression="DESTLAB" >
                <ItemTemplate>
                    <%#Eval("DESTLAB")%> - <%#Eval("DESTKEY")%>
                </ItemTemplate>
                <EditItemTemplate>
                    <asp:DropDownList ID="ReferenceList" runat="server" DataSourceID="ReferenceListDB"
                     DataTextField="REFLAB" DataValueField="REFKEY"
                     SelectedValue='<%#Bind("DESTKEY")  %>' TabIndex="0">
                     </asp:DropDownList>
                </EditItemTemplate>
            </asp:TemplateField>            
        </Columns>
</asp:GridView>  
--------------------------------------------------------------------------

Je pense que c'est le Ctype qui ne permet pas de retourner ce que je souhaite!

Merci pour votre aide

Bonjour,
Excuse moi de répondre à la suite de ce mail, mais j'ai urgemment besoin d'aide.
Je veux éxécuter 2 requetes à la suite et je finis par avoir un "Illegal name/number variable" sur le dernier excecuteNonQuery(), et je comprends pas pkoi, je l'ai déjà fais autre part cette enchainement et ça marche très bien!!!
