Asp with vb.net codebehind, httpfilecollection loses data

Question

I have an html input that i use to upload files. Now on my page when I try to authenticate a user first, and hide the div that the controls are in for my file uploads, the collection is empty. When I dont use runat = "server", it works as expected. Not sure how to get around this.

Code: Here is what works...but without hiding... not what I want.

        <div id="attachments">
            Attachments to add:
            <div id="divFileInputs">
                <input id="file1" runat="server" name="fileInput" type="file" size="50" style="width: 50em"
                    onfocus="AddFileInput()"  /></div>
            <br />
            <select id="selectFileList" name="ListBox1" size="5" style="width: 50em; text-align: left" />
            <br />
            <input id="RemoveAttachmentButton" onclick="RemoveFileInput()" type="button" value="Remove"
                class="removebutton " /><br />
            <br />
        </div>

Here is the code behind that uses it:

 Protected Sub CopyAttachments(ByVal issueId As String)

    Dim files As HttpFileCollection = Request.Files
    Dim myStream As System.IO.Stream

    Dim hardwareService As New localhost.Service
    For i As Integer = 0 To files.Count - 1

        Dim postedFile As HttpPostedFile = files(i)
        Dim fileNameWithoutPath As String = System.IO.Path.GetFileName(postedFile.FileName)

        If fileNameWithoutPath.Length > 0 And issueId.Length > 0 Then
            Dim fileLength As Integer = postedFile.ContentLength
            Dim fileContents(fileLength) As Byte

            ' Read the file into the byte array.  Send it to the web service.
            myStream = postedFile.InputStream
            myStream.Read(fileContents, 0, fileLength)
            hardwareService.ClearQuestAttachToIssue(issueId, fileNameWithoutPath, fileContents)
        End If
    Next

    hardwareService = Nothing
End Sub

Thanks in advance!!!
