I can give you an example with c#
First Create Default.aspx and paste code

ASP.NET

<![CDATA[<%@ Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit" TagPrefix="atk" %>
<asp:content id="Content1" contentplaceholderid="HeadContent" runat="Server" xmlns:asp="#unknown">
<style type="text/css">
       
                .modalBackground
                {
                       background-color: Gray;
                        filter: alpha(opacity=80);
                        opacity: 0.8;
                        z-index: 10000;
                }
    
    </style>
</asp:content>
<asp:content id="Content2" contentplaceholderid="MainContent" runat="Server" xmlns:asp="#unknown"> 
<hr />
    <asp:label id="lbltotalRow" runat="server" text=""></asp:label>
<asp:panel id="Panel1" runat="server" height="310px" scrollbars="Vertical">

    <asp:gridview id="grdviewFileList" runat="server">
         Width="890px"  >
      <columns>  
         
            <asp:templatefield>
                <itemtemplate>
 <asp:linkbutton id="lnkView" text="Download" runat="server" onclick="DownloadFile"></asp:linkbutton>
                </itemtemplate>
            </asp:templatefield>                     

            </columns>
        
    </asp:gridview>
</asp:panel></asp:content>



  /////////////////////////// Start /////////////////////  PopupView Panel  ///////////////////////////////// /////////////////////  
          <asp:button id="btnShowPopup" runat="server" style="display:none" xmlns:asp="#unknown" />
         
        <atk:modalpopupextender id="ModalPopupExtender1"  runat="server" targetcontrolid="btnShowPopup" popupcontrolid="PopupView" xmlns:atk="#unknown">
            CancelControlID="btnCancel" BackgroundCssClass="modalBackground">
        </atk:modalpopupextender>

Default.cs

C#

String ConnectionString = ConfigurationManager.ConnectionStrings["YourConnectionStringsname"].ConnectionString;
   protected void Page_Load(object sender, EventArgs e)
   {
       if (!Page.IsPostBack)
       {
           DatabindFileList();
           
       }

   }

 public void DatabindFileList()
    {
       
        try
        {
            SqlConnection con = new SqlConnection(ConnectionString);
            SqlCommand cmd = new SqlCommand("SP_DataBindFileList", con);
            cmd.CommandType = CommandType.StoredProcedure;
           // cmd.Parameters.AddWithValue("@Sub_categoryID", sub_categoryname);
            con.Open();
            grdviewFileList.EmptyDataText = "No Records Found";
            grdviewFileList.DataSource = cmd.ExecuteReader();
            grdviewFileList.DataBind();

            lbltotalRow.Text = "Total : " + Convert.ToString(grdviewFileList.Rows.Count) + " Records found" + "<br />";
        }
        catch  
        {
             
        }
    }
 protected void DownloadFile(object sender, EventArgs e)
  {
      string filePath = (sender as LinkButton).CommandArgument;    
     iframe.Attributes.Add("src", filePath);
     this.ModalPopupExtender1.Show();
  }
