how to upload and view pdf files using file upload control ?

In this i would like to explain about upload pdf and view, using file upload control .

here i will explain already we studied about upload control in previous chapter.

So

code in .aspx page:

<form>

<div>

 Upload:<asp:FileUpload runat="server" ID="fileUpload" />

        <br />

        <asp:Button ID="Button1" runat="server" Text="Upload" OnClick="FileUpload_Click" />

        <asp:HyperLink  runat="server" ID="lnkButton" Text="View File" />

    </div>

    </form>

code in .aspx.cs page:

  Add name space using sytem .IO;

//code in button click event.

Add  folder in solution explorer Resumes

 protected void FileUpload_Click(object sender, EventArgs e)

        {

            if (fileUpload.HasFile)

            {

                string strpath = "~/Resumes" + fileUpload.FileName;

                fileUpload.SaveAs(Server.MapPath(strpath));

                lnkButton.NavigateUrl = "~/Resumes/" + fileUpload.FileName;

//This link button redirects to our resume folder and display the pdf file.

                Response.Write("<script>alert('uploaded successfully');</script>");

            }

}

So your pdf is uploaded  here and if you click on view file then it show your pdf file formate.
maximum size for uploading a pdf file is 4096 i.e, 4mb only.
you will specify the size limit in web config file.
In <system.web> tag
system.web>
      <httpRuntime executionTimeout="90" maxRequestLength="16834" useFullyQualifiedRedirectUrl="false"
minFreeThreads="8"
minLocalRequestFreeThreads="4"
appRequestQueueLimit="100"
enableVersionHeader="true" />
(4096 for 4mb it is default,8192 for 8mb,16384 for 16 mb, 65536 for 64 mb .............
I hope you understand .

if you get any queries about this post a comment.
