Place A Hyperlink Field In A Webpage At Runtime?

I am trying to display contents of a folder in a hyperlink. I am using masterpage also. The hyperlinks are not shown into the content page. what to do for that?

I know in windows forms we can use like TextBox.Location=new Point(100,100);

But how to do in web page..

my coding in page_load is

protected void Page_Load(object sender, EventArgs e)
{
DirectoryInfo di = new DirectoryInfo(Server.MapPath("~/ProjectsUpload"));
int i = 0;
foreach (FileInfo fi in di.GetFiles())
{
HyperLink HL = new HyperLink();
HL.ID = "HyperLink" + i++;
HL.Text = fi.Name;
HL.NavigateUrl = "downloading.aspx?file=" + fi.Name;
Page.Controls.Add(HL);
Page.Controls.Add(new LiteralControl("<br/>"));
}
}
