why would this routine return a blank page when the same code worked when in a page load method. now that it is in a function it runs but does not show any datalist items on the page?? Is it because I am using a collection and need to import a namespace?

<%@ Import Namespace="System" %>
<%@ Import Namespace="System.Data" %>
<%@ Import Namespace="System.Data.SqlClient" %>
<%@ Import Namespace="System.Web" %>

<html>
<head>

<script language="VB" runat="server">

Function CreateDataSource() As ICollection ' Create Instance of Connection and Command Object
Dim myConnection As SqlConnection = New SqlConnection(ConfigurationSettings.AppSettings("ConnectionString"))
Dim myCommand As SqlCommand = New SqlCommand("DocumentSearch", myConnection)

' Mark the Command as a SPROC
myCommand.CommandType = CommandType.StoredProcedure

' Add Parameters to SPROC
Dim parameterSearch As SqlParameter = New SqlParameter("@Search", SqlDbType.NVarChar, 255)
parameterSearch.Value = "" 'Request.Params("txtSearch")
myCommand.Parameters.Add(parameterSearch)

' Execute the command
myConnection.Open()

DataList1.DataSource = myCommand.ExecuteReader(CommandBehavior.CloseConnection)
DataList1.DataBind()
End Function

Sub Page_Load(sender As Object, e As EventArgs)

If Not IsPostBack Then
BindList
End If

End Sub

Sub BindList
DataList1.DataSource= CreateDataSource()
DataList1.DataBind
End Sub

Sub DataList_ItemCommand(sender As Object, e As DataListCommandEventArgs)
Dim cmd As String = e.CommandSource.CommandName
If cmd = "select" Then
DataList1.SelectedIndex = e.Item.ItemIndex
End If

BindList
End Sub
