Help needed - nested detailsview referencing

1 New Member
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"

I am passing the whole object instead or parameters in my select and update methods. I can get the updated object if I set UpdateMethod, let ASP.NET autogenerate an update button, and then press update after making changes, but I don't want that update button. How can I get the updated object when the user presses one of my other action buttons?

Hi all, I am using python to drive another tool using pexpect. The values which I get back I would like to automatically put into a list if there is more than one return value. They provide me a way to see that the data is in set by parenthesising it. This is all generated as I said using pexpect - Here is how I use it.. child = pexpect.spawn( _buildCadenceExe(), timeout=timeout) child.sendline("somefunction()")

My users are used to having an image to click on then bring up a pop-up Calendar Control to populate the textbox with the date.

Hi, I've been trying different ways of getting an insert button within a detailsview control to be the default button when the return key is pressed. Using a panel and itemtemplates I get the exception "{"The DefaultButton of '' must be the ID of a control of type IButtonControl."} - why it thinks I'm referencing ''? Is it a scope issue because the button is within the itemtemplate?
