Asp.net Open PDF File in Web Browser using C#, VB.NET

Nov 5, 2012
Introduction

Here I will explain how to open pdf file in web browser in asp.net using C# and VB.NET.

Description

In previous articles I explained Export Gridview data to PDF, Send values from one page to another page using QueryString, Joins in SQL Server, Highlight Gridview records based on search and many articles relating to Gridview, SQL ,jQuery,asp.net, C#,VB.NET. Now I will explain how to open pdf file in web browser in asp.net using C# and VB.NET.

To implement this concept first create one new website and add one of your existing pdf file to your website after that open Default.aspx page and write the following code 


<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title>Open PDF File in Web Browser in asp.net</title>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:Button ID="btnOpen" Text="1st Way to Show PDF In Browser" Font-Bold="true" runat="server" onclick="btnOpen_Click" />
<asp:Button ID="btnpdf" Text="2nd Way to Show PDF In Browser" Font-Bold="true" runat="server" onclick="btnpdf_Click" />
</div>
</form>
</body>
</html>
Now open Default.aspx code behind file and add following namespaces

C# Code


using System;
using System.Net;
Once namespaces added write the following code 


protected void Page_Load(object sender, EventArgs e)
{
}
// First Way to show PDF in browser
protected void btnOpen_Click(object sender, EventArgs e)
{
Response.Redirect("SiteAnalytics.pdf");
}
// Second way to Show PDF in browser by setting Content Type of the Response object and add the binary form of the pdf in the header
protected void btnpdf_Click(object sender, EventArgs e)
{
string path = Server.MapPath("SiteAnalytics.pdf");
WebClient client = new WebClient();
Byte[] buffer = client.DownloadData(path);

if (buffer != null)
{
Response.ContentType = "application/pdf";
Response.AddHeader("content-length", buffer.Length.ToString());
Response.BinaryWrite(buffer);
}
}
VB.NET Code


Imports System.Net

Partial Class VBCodetoShowPDF
Inherits System.Web.UI.Page
Protected Sub Page_Load(sender As Object, e As EventArgs)

End Sub
' First Way to show PDF in browser
Protected Sub btnOpen_Click(sender As Object, e As EventArgs)
Response.Redirect("SiteAnalytics.pdf")
End Sub
' Second way to Show PDF in browser by setting Content Type of the Response object and add the binary form of the pdf in the header
Protected Sub btnpdf_Click(sender As Object, e As EventArgs)
Dim path As String = Server.MapPath("SiteAnalytics.pdf")
Dim client As New WebClient()
Dim buffer As [Byte]() = client.DownloadData(path)

If buffer IsNot Nothing Then
Response.ContentType = "application/pdf"
Response.AddHeader("content-length", buffer.Length.ToString())
Response.BinaryWrite(buffer)
End If
End Sub
End Class
