Default problem with populating ddl in edit of detailsview

Hi,

i defined a dropdownlist in an EditTemplate of a detailsview like this:

<EditItemTemplate>
<asp:DropDownList ID="drop1" runat="server"></asp:DropDownList>
</EditItemTemplate>

I want to populate it in code-behind; i tried this:

Protected Sub DetailsView1_ItemCreated(ByVal sender As Object, ByVal e As
System.EventArgs) Handles DetailsView1.ItemCreated
        If DataControlRowState.Edit Then 'only in edit mode
            If DataControlRowType.DataRow Then 'only datarow
                Dim dd1 As DropDownList
                Dim z1 As ListItem
                Dim i As Integer
                dd1 = CType(DetailsView1.Rows(5).FindControl("drop1"),
DropDownList)
                For i = 0 To 20
                z1 = New ListItem(i, i)
                dd1.Items.Add(z1)
                Next
            End If
        End If
    End Sub

But i get the error:"Object reference not set to an instance of an object"
at line: dd1.Items.Add(z1)

Thanks for help
H.
