Answer 1

Use ListBox for this. It will be something like:

protected void UploadButton_Click(object sender, EventArgs e){
    foreach (HttpPostedFile fl in fu.PostedFiles)
    {
        fl.SaveAs(DestinationPath + fl.FileName);
        ListItem li = new ListItem();
        li.Text = fl.FileName;
        ListBox1.Items.Add(li);
    }
}

In your design page:

<asp:Panel ID="pnlFiles" runat="server" />

Your code behind:

Protected Sub Button1_Click(ByVal sender As Object, _ByVal e As System.EventArgs)
    For Each fl as HttpPostedFile in fu.PostedFiles
        Dim fileLink as String = DestinationPath + fl.FileName
        fl.SaveAs(fileLink)
        Dim hpr as New HyperLink
        hpr.Text = "Download file"
        hpr.NavigateUrl = fileLink
        pnlFiles.Controls.Add(hpr)
    Next
End Sub
