I have an ASP.NET user control that includes some javascript. The control
file (ascx) and javascript file (.js) are both in the same path. However,
when I have an ASPX page in a different directory that uses the control, the
javascript doesn't get referenced properly (I'm guessing that the control is
trying to load the javascript relative to the ASPX page that calls it).
Here is some code from the user control:

<%@ Control Language="vb" AutoEventWireup="false" Codebehind="Title.ascx.vb"
Inherits="presto.Title"
TargetSchema="http://schemas.microsoft.com/intellisense/ie5"; %>
<script language="javascript" src="title.js"></script>

I can put the full path to the application in the src attribute and that
will work, but that means I have the absolute path which I don't want. Or,
I could simply put the .js file in the control. But I don't want that
either. Is there any other way to get this to work (ie- something that says
include this file from the controls directory, no matter where the control
is getting called from)?

Thanks,
Greg

You could declare a public variable in the ascx file that gets set during
the onload of each of the parent pages like so.

'in your user control code behind
Public javaSource As String
Protected javaString As System.Web.UI.WebControls.Literal

Private Sub Page_Load(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles MyBase.Load
    If Not IsPostBack Then
        javaString.Text = "<script langugage=""javascript"" src="""
& javaSource & """></script>"
    End If
End Sub

'in your user control front end
<html>
<head>
<title>WebForm1</title>
</head>
<body>
<asp:literal id="javaString" runat="server"></asp:literal>
<form>
</form>
</body>
</html>

'in your parent page
Protected myControl As MyControlPage

Private Sub Page_Load(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles MyBase.Load
    If Not IsPostBack Then
        myControl.javaSource = "../includes/java.js"
    End If
End Sub

Another approach is for each app directory to have a sub-virtual directory that points to a common virtual directory. The common virtual directory would contain your ascx and javascript files. Then you could always reference the files the same way, regardless of application. Something like this...

/IncludeDir        #store ascx and js file here
/App1/IncludeDir #points to /IncludeDir
/App2/IncludeDir    #points to /IncludeDir
/App3/IncludeDir    #points to /IncludeDir

Steve Smith has an article that explains this at:

Hope that helps,
Jon
