I have a web form(page1.aspx) that requests 4 different recordsets from an sql 2000 server. In the page1 codebehind I bind the first 3 recordsets to 3 different datalists. I would like to bind the 4th recordset to a Datalist that is contained in a user control. I am an intermediate level programmer so details would be great. Thanks in advance

Forget about recordser, think ADO.NET with Datasets and DataTable

Dranizz I'm not sure what you mean. Maybe I am using the wrong terms.

Well, in VB.NET we don't use recordset anymore, we use Datasets.
They are real representation of your data in the database, and it's disconnected.

Here is the code that I have

Private Sub getDataAndFill()
        Dim myDataSet As New DataSet
        Dim MyDataAdapter As SqlDataAdapter
        Dim ConString As String = ""
        'CONNECT TO DATABASE
        ConString = ConfigurationSettings.AppSettings("readDbConnString")
        MyDataAdapter = New SqlDataAdapter("Stored_HomePage", ConString)
        MyDataAdapter.SelectCommand.CommandType = CommandType.StoredProcedure
        'FILL DATALISTS
        MyDataAdapter.Fill(myDataSet)
        'BLOG ARCHIVE

        DLBlogArchive.DataSource = myDataSet
        DLBlogArchive.DataMember = "Table"
        'BLOG
        DLBlog.DataSource = myDataSet
        DLBlog.DataMember = "Table1"
        'PHOTOS
        DLPopularPhotos.DataSource = myDataSet
        DLPopularPhotos.DataMember = "Table2"
        'LINKS
        DLPopularLinks.DataSource = myDataSet
        DLPopularLinks.DataMember = "Table3"
       
        'BIND
        DLBlogArchive.DataBind()

        DLBlog.DataBind()
        DLPopularPhotos.DataBind()
        DLPopularLinks.DataBind()

    End Sub


the DLBlogArchive is the datalist that I want to put on the web control since many pages will use it.

by the way datalist is the control, Dataset is what you fill, it's a class
what is the problem exactly?

I may be using the wrong terms.
I want to store the datalist in blogArchiveList.ascx  and then fill the list from the page1.aspx code behind/

use a session
save it on a session like this

On load

Session("Data")=myDataSet

and to get it back

dim data as Dataset

data=Session("Data")

hum...
then use the transfer method

Set to public attributes for your 2 strings in the Page1 class

like

Public Dataset Data;


server.Transfer("Page2.aspx",true);

And at page2 load you'll do this

System.Collections.Specialized.NameValueCollection ColForm;
'Get the data from the source form
colForm=Request.Form

and gets the value from the source form

dim ds as Dataset
ds=  colForm["Data"]

maybe there is a better way then. The reason I am using a ascx page is because the blog archive is something that I want to use on almost every page. In old ASP I would use an include file.

but if you use your ascx in a form and save the dataset in that form, then use the transfer, it could work

That's what I would do.

Use a property in the ascx to indicate the dataset to use or to save
