Help needed - nested detailsview referencing

[sansie]

Hi,

I have a page which is basically a details view(in inset mode) inside a datalist.
The problem is I want to set the field "invoiceID" (of the detailsview) to an invoiceID coming through the query string of the page.

Now, I have sucessfully done this with a detailsview that is not enclosed in a datalist, using the following page load script:

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArg s) Handles Me.Load

Dim Invoiceid As TextBox = CType(DetailsVi ew1.FindControl ("Invoiceid" ), TextBox)
Invoiceid.Text = Request.QuerySt ring("Invoiceid ")
End Sub


however when I enclosed the detailsview in a datalist, it suddenly stopped working,

The first error I get is

Compiler Error Message: BC30451: Name 'DetailsView1' is not declared.

Line 9: Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArg s) Handles Me.Load
Line 10:
Line 11: Dim Invoiceid As TextBox = CType(DetailsVi ew1.FindControl ("Invoiceid" ), TextBox)
Line 12: Invoiceid.Text = Request.QuerySt ring("Invoiceid ")
Line 13: End Sub



My code is below:



<asp:DataList ID="DataList1" runat="server" DataKeyField="T estID" DataSourceID="O bjectDataSource 2"

Can anyone tell me how to reference the Invoice ID textbox in the detailsview, and then set it to a request.queryst ring value?
