Hi pankaj123,
I have created sample code by refering the below article which full-fill your requirement.
HTML
<form id="form1" runat="server">
<div>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>
<script type="text/javascript">
$(function () {
$('[Id*=FileUpload1]').change(function () {
$('[Id*=btnView]').click();
});
});
</script>
</div>
<div>
<asp:FileUpload ID="FileUpload1" runat="server" />
<br />
<asp:Literal ID="ltEmbed" runat="server" />
<br />
<asp:Button ID="btnView" Text="Submit" OnClick="OnCheck" Style="display: none" runat="server" />
</div>
</form>
C#
protected void OnCheck(object sender, EventArgs e)
{
ltEmbed.Visible = true;
Viewme();
}
private void Viewme()
{
using (Stream fs = FileUpload1.PostedFile.InputStream)
{
using (BinaryReader br = new BinaryReader(fs))
{
byte[] bytes = br.ReadBytes((Int32)fs.Length);
Session["ByteArray"] = bytes;
Session["FileName"] = FileUpload1.PostedFile.FileName;
string filename = Path.GetFileName(FileUpload1.PostedFile.FileName);
string contentType = FileUpload1.PostedFile.ContentType;
string embed = "<object data=\"{0}\" type=\"application/pdf\" width=\"500px\" height=\"300px\">";
embed += "If you are unable to view file, you can download from <a href = \"{0}\">here</a>";
embed += " or download <a target = \"_blank\" href = \"http://get.adobe.com/reader/\">Adobe PDF Reader</a> to view the file.";
embed += "</object>";
ltEmbed.Text = string.Format(embed, ResolveUrl("~/PdfViewer_Handler.ashx"));
}
}
}
PdfView_Handler.ashx
<%@ WebHandler Language="C#" Class="PdfViewer_Handler" %>
using System;
using System.Web;
public class PdfViewer_Handler : IHttpHandler, System.Web.SessionState.IRequiresSessionState
{
public void ProcessRequest(HttpContext context)
{
byte[] bytes = context.Session["ByteArray"] as byte[];
string fileName = context.Session["FileName"].ToString();
context.Response.Buffer = true;
context.Response.Charset = "";
context.Response.Cache.SetCacheability(HttpCacheability.NoCache);
context.Response.ContentType = "application/pdf";
context.Response.BinaryWrite(bytes);
context.Response.Flush();
context.Response.End();
}
public bool IsReusable
{
get
{
return false;
}
}
}
