Upload and Show PDF in Website

Just follow these steps.

1) Create a Class Library project. I create a Visual C# Class Library project using Visual Studio and select C# as language and give it a name. I give my project name ShMyPdf.

I change the existing class. I change class name to DisplayPdf and it is inherited from WebControl class.

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Text;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;

namespace ShMyPdf
{
public class DisplayPdf : WebControl
{
private string _filepath;
public string FilePath
{
get
{
return _filepath;
}
set
{
if (string.IsNullOrEmpty(value))
{
_filepath = string.Empty;
}
else
{
int tild = -1;
//check ~ symbol including in pdf path then remove
tild = value.IndexOf('~');
if (tild != -1)
{
_filepath = value.Substring((tild + 2)).Trim();
}
else
{
_filepath = value;
}
}
}
}

protected override void RenderContents(HtmlTextWriter writer)
{
try
{
StringBuilder sb = new StringBuilder();
sb.Append("<iframe src=" + Convert.ToString(FilePath) + " ");
//fix height and width
sb.Append("width=800px height=500px");
sb.Append("<View PDF: <a href=" + Convert.ToString(FilePath) + "</a></p> ");
sb.Append("</iframe>");
writer.RenderBeginTag(HtmlTextWriterTag.Div);
writer.Write(Convert.ToString(sb));
writer.RenderEndTag();
}
catch
{
//If any problem in the PDF at that time display below information
writer.RenderBeginTag(HtmlTextWriterTag.Div);
writer.Write("PDF Control...");
writer.RenderEndTag();
}
}
}
}

2) Run the project. It will generate a dll called ShMyPdf.dll.

3) Create a new ASP.NET Web Application using Visual Studio. I give my application DemoPDFViewer. I select C# as language in Visual Studio.

In this application, user can upload a PDF file and view it.

a. Add a reference to ShMyPdf.dll

b. Make a PDF folder on the site and make sure you have write permissions set on this folder.

c. Add Upload PDF functionality

This is how my page looks like.

ASPX Code :

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %>

<%@ Register Assembly="ShMyPdf" Namespace="ShMyPdf" TagPrefix="PdfViewer" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title>PDF View Online</title>
</head>
<body>
<form id="form1" runat="server">
<div>
<center>
<table>
<tr>
<td colspan="2" align="center" style="font-family: Verdana; font-size: larger">
Online PDF Viewer
</td>
</tr>
<tr>
<td>
Upload PDF File
</td>
<td>
<asp:FileUpload ID="fup" runat="server" />
</td>
</tr>
<tr>
<td colspan="2">
<asp:Button ID="btnUpload" runat="server" Text="Upload" OnClick="btnUpload_Click" />
</td>
</tr>
<tr>
<td>
<asp:Label ID="lblMsg" runat="server" ViewStateMode="Disabled" Font-Bold="true" ForeColor="Red"></asp:Label>
</td>
</tr>
<tr>
<td colspan="2" align="center">
<asp:Button ID="btnView" Text="View PDF" runat="server" Visible="false" OnClick="btnView_Click" />
</td>
</tr>
<tr>
<td colspan="2" id="pnlPDFViewer" visible="false" runat="server">
<asp:HyperLink ID="HyperLink1" runat="server">Open PDF into New Page</asp:HyperLink>
<br />
<PdfViewer:DisplayPdf ID="displaypdf1" runat="server" BorderStyle="Inset" BorderWidth="2px"
Style="height: 500px;" Width="800px" />
</td>
</tr>
</table>
</center>
</div>
</form>
</body>
</html>

CS Code:

using System;
using System.Data;
using System.Configuration;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;
using System.Drawing;

public partial class _Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{

}

public string Uploadedfilename { get { return Convert.ToString(ViewState["filename"]); } set { ViewState["filename"] = value; } }

protected void btnUpload_Click(object sender, EventArgs e)
{
if (fup.HasFile)
{
string strFilePath = Server.MapPath("PDF") + "\\";
Uploadedfilename = Convert.ToString(Guid.NewGuid()) + ".pdf";
strFilePath = strFilePath + Uploadedfilename;
fup.SaveAs(strFilePath);
lblMsg.ForeColor = Color.Blue;
lblMsg.Text = "PDF File Upload Successfully";
btnView.Visible = true;
}
else
{
lblMsg.Text = "Please Upload PDF File";
}
}
protected void btnView_Click(object sender, EventArgs e)
{
pnlPDFViewer.Visible = true;
displaypdf1.FilePath = @"~/pdf/" + Uploadedfilename;
HyperLink1.NavigateUrl = @"~/pdf/" + Uploadedfilename;
}
}

4) compile code and run application.
