Can the results of my search be links to pages?

I have a search engine on my ASP.net 4.0 VB site that in which I need to link the search results with their individual pages. I understand that this can be done simply with a submit button after the search textbox but a submit button wouldn't fit next to the search bar on my page, plus it wouldn't look right.

Can the results of my search be links to pages?

The old way, the results were stored in a hidden div where they became links to their pages. I was hoping that the code I have of the old search could be incorporated into the new search, but I do not know where it would go. The only way I can think of to do it is to place the code in the webservice in a while or for loop. I may be way off base here, but that is why I am asking what the best way to go about this would be?

<WebMethod()> _
Public Function GetCompletionList(ByVal prefixText As String, ByVal count As Integer) As String()
    Dim ProductSql As String = "Select ProductName FROM Product WHERE ProductName LIKE '" & prefixText & "%'"
    Dim sqlConn As New SqlConnection
    sqlConn.Open()
    Dim myCommand As New SqlCommand(ProductSql, sqlConn)
    Dim myReader As SqlDataReader = myCommand.ExecuteReader()
    Dim myTable As New DataTable
    myTable.TableName = "ProductSearch"
    myTable.Load(myReader)
    sqlConn.Close()
    Dim items As String() = New String(myTable.Rows.Count - 1) {}
    Dim i As Integer = 0
    For Each dr As DataRow In myTable.Rows
        items.SetValue(dr("ProductName").ToString(), i)
        i += 1
    Next
    Return items
End Function

        <asp:ScriptManager ID="ScriptManager1" runat="server">
    <Services>
        <asp:ServiceReference Path="ProductSearch.asmx" />
    </Services>
</asp:ScriptManager>
    <asp:TextBox ID="Search" runat="server" AutoComplete="off"></asp:TextBox>
    <asp:AutoCompleteExtender ID="AutoCompleteExtender1" runat="server" TargetControlID="Search" ServicePath="~/ProductS开发者_JAVA百科earch.asmx" ServiceMethod="GetCompletionList" MinimumPrefixLength="1" CompletionSetCount="120" EnableCaching="true" CompletionListCssClass="results">
    </asp:AutoCompleteExtender>


I used a little javascript to make links out of the results of my search engine query. This is what I have now - although the For Each loop in the Web Service doesn't work properly.

<asp:Content ID="Content1" ContentPlaceHolderID="head" Runat="Server">
<script type="text/javascript">
function AutoCompleteClientMethod(source, eventArgs) {
    var value = eventArgs.get_value();
    window.location = ("/Product/Default.aspx?id=" + value)
} 
</script>
</asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="body" Runat="Server">
    <asp:ScriptManager ID="ScriptManager1" runat="server">
    <Services>
        <asp:ServiceReference Path="ProductSearch.asmx" />
    </Services>
</asp:ScriptManager>
    <asp:TextBox ID="Search" runat="server" AutoComplete="off"></asp:TextBox>
    <asp:AutoCompleteExtender ID="AutoCompleteExtender1" runat="server" TargetControlID="Search" ServicePath="~/ProductSearch.asmx" ServiceMethod="GetProducts" MinimumPrefixLength="1" CompletionSetCount="120" EnableCaching="true" OnClientItemSelected="AutoCompleteClientMethod">
    </asp:AutoCompleteExtender>
</asp:Content>


<WebMethod()> _
Public Function GetProducts(ByVal prefixText As String, ByVal count As Integer) As String()
    Dim ProductSql As String = "Select ProductID, ProductName FROM Product WHERE ProductName LIKE '" & prefixText & "%'"
    Dim sqlConn As New SqlConnection
    sqlConn.Open()
    Dim myCommand As New SqlCommand(ProductSql, sqlConn)
    Dim myReader As SqlDataReader = myCommand.ExecuteReader()
    Dim myTable As New DataTable
    myTable.TableName = "ProductSearch"
    myTable.Load(myReader)
    sqlConn.Close()
    Dim items As String() = New String(myTable.Rows.Count - 1) {}
    Dim i As Integer = 0
    For Each dr As DataRow In myTable.Rows
        items.SetValue(dr("ProductName").ToString(), i)
        i += 1
    Next
    Return items
End Function
End Class
