How to display a page in another page multiple times at same time

IFrame

Hello,
I have a page that displays salary of a staff. In another page I want to show this page like if we have 10 staff then for all the 10 staff that particular page is shown separately at the same time.

I'm using I frame to do so but it only shows single page for one staff only. Please help me with the issue.
My code behind to access the salary page is

protected void BindPrimaryGrid()
    {
        con.Open();
        SqlDataAdapter sda = new SqlDataAdapter("select * from Salary Where Year='" + Year + "' AND Month='" + PreviousMonth + "' AND Updated='True'";, con);
        DataTable dt = new DataTable();
        sda.Fill(dt);
        con.Close();
        if (dt.Rows.Count > 0)
        {
            for (int i = 0; i < dt.Rows.Count; i++)
            {
                HtmlIframe ifrm = new HtmlIframe();
                ifrm.ID = dt.Rows[i]["REFNo"].ToString();
                ifrm.Src = "StaffSalaryPrint.aspx?REFNo=" + dt.Rows[i]["REFNo"].ToString();
                pnlContents.Controls.Add(ifrm);
            }         
        }

What I have tried:

I've tried to add Iframes dyanamically to do so.
But sadly it doesn't work. Iframe only works for a single row and not in a loop.
