how to pass value from asp.net server control using jQuery?
<p>I UPDATED the code with code behind. I'm doing something dynamic with the label contrtol.</p>

<p>I have the following jQuery code working as it is (passing the value of 'test") but what I want to do is to pass the value of the label control (lblNames). I'm using the label control to collect the uploaded file names. Is there a way?</p>

<p>jQuery:</p>

<pre><code>$(document).ready(function () {
    $("#btnUpload").click(function () {
        $("#Notes", top.document).val('test');
    });
});
</code></pre>

<p>ASPX code:</p>

<pre><code>&lt;asp:Label ID="lblNames" runat="server" visible="true" &gt;&lt;/asp:Label&gt;
</code></pre>

<p>Code Behind:</p>

<pre><code>    Protected Sub btnUpload_Click(ByVal sender As Object, ByVal e As System.EventArgs)    Handles btnUpload.Click
    Dim fileExt As String
    fileExt = System.IO.Path.GetExtension(FileUpload1.FileName)

    If (fileExt &lt;&gt; ".exe") Then
        Dim fileNames As New List(Of String)

        Try
            Dim hfc As HttpFileCollection = Request.Files
            lblFiles.Text = String.Empty
            lblNames.Text = String.Empty

            For i As Integer = 0 To hfc.Count - 1
                Dim hpf As HttpPostedFile = hfc(i)
                If hpf.ContentLength &gt; 0 Then
                    fileNames.Add(hpf.FileName)
                    hpf.SaveAs(Server.MapPath("/directory") &amp; "\" &amp; System.IO.Path.GetFileName(hpf.FileName))
                    lblFiles.Text += "&lt;b&gt;File: &lt;/b&gt;" &amp; hpf.FileName &amp; "     " &amp; "    Uploaded Successfully! &lt;br /&gt;"
                    lblNames.Text += hpf.FileName &amp; ", "
                Else
                    lblWarning.Text = "Please choose a file to upload."
                End If
            Next i
        Catch ex As Exception

        End Try
</code></pre>
