Web Forms :: Downloading A File With C#?
Aug 10, 2010
i am making a gridview in which textfield of password should match with the password stored in the database (table) .As soon as that happens, the file should be ready to download . now the problem is that the code is niether working nor showing any error, which is very sarcastic.
if (txtval.Text != null || txtval.Text !="")
{
if (txtval.Text == ds.Tables[0].Rows[0]["FilePassword"].ToString())
{
lblmessage.Text = "File has been downloaded successfully.";
WebClient fileReader = new WebClient();..........

I have made an application where I am displaying the .pdf , .doc , .docx files. These files are uploading from an Admin Panel.When user place a mouse pointer on download icon provided in front of every file, it shows the complete path where it’s get saved.I want to avoid this path visibility even when user place mouse on download icon and even if it Inspect an element (as most modern browser will have this functionality).

we are working on a file download page. We want to download a file with a name with spaces and accents. Although the filename is shown correctly on the filedownload dialog, when we click open, the file name is shown with %e1%ba%a3n%20... on notepad. ('Save as' shows the correct name) This problem only happens in Internet Explorer.
Is there anyway we can Display the file name correctly (on the target application) after opening it (without saving) from file download dialog ?
We use this code to set the filename :
fileName = Server.UrlPathEncode(fileName);
Response.AppendHeader("Content-Disposition", "attachment; filename="" + fileName + """);

I have 4 checkboxes named(Laptop, Car, Phone, TV) and a button. when user checks one Car checkbox and clicks a button, car specifications pdf should be downloaded. Similarly when phone or laptop checkbox checked, relevant pdf's should be downloaded. For this i have written following code
[Code]....
This code is working well in VS2008 but has issues when run in localhost.
Issue --> Check one checkbox like chkPhone and click on button, the Phone pdf gets downloaded and uncheck chkPhone checkbox and check other one like chkCar and when clicked on button to download, getting following errors.
1. xml parsing error not well-formed --> this error is getting only in mozilla.
2. HTTP/1.1 100 Continue Server: Microsoft-IIS/5.1 Date: Wed, 09 Mar 2011 05:34:23 GMT X-Powered-By: ASP.NET HTTP/1.1 200 OK Server: Microsoft-IIS/5.1 Date: Wed, 09 Mar 2011 05:34:23 GMT X-Powered-By: ASP.NET X-AspNet-Version: 2.0.50727 Content-disposition: attachment; filename=Car.pdf;
I have googled the issues and find the following sites[URL] For second issue i added the following line
System.Net.ServicePointManager.Expect100Continue = false;
but still sometimes iam getting the same error. Sometimes these errors raise after downloading 2 files and when tried to download 3rd one.

Ive created a Web App where it is possible to download an xml file from the server to the client. It works just fine except that the Save Dialog recognizes the file being dowloaded as of type .aspx and the name of the file as being the name of the page I' on. The page is called Download.aspx and it contains a button that when clicked executes the following code:
[Code]....
The save dialog appears and says:
Name: Download.aspx
Type: ASP.NET Server Page, 1,16KB
From: 127.0.0.1
If I download the file and open it it contains the correct Xml file content and nothing else, so it is working correctly. It just annoys me that it appears to the user that he is downloading the aspx site (and it shows up as such in windows explorer as well) rather than the xml file which is the actual content.

I have a page that has a note to the user about the file they're about to download and a button to click to start the download. When they click the button, it does a Response.Redirect to another page with the following code in its Page_Load:
Response.Clear()
Response.Buffer = True
Response.AppendHeader("Content-disposition", "attachment; filename=" & FileName)
Response.AppendHeader("Content-length", FileSize.ToString)
Response.ContentType = "application/download"
Response.WriteFile(Page.ResolveUrl(FilePath))
Response.Flush()
Response.End()
I want the download to start and then I want this page (which is a tab in the browser) to close.
The code to download the file works fine. I just can't figure out how to close this tab when it's finished. I've read a lot of forum posts from people who are using similar code, but none of the suggestions seem to work for me. I understand that Response.End means that I can't put any more code this page; it will be ignored. But how do I get this tab to close?

I have code to actually create a CSV file from a Gridview control. What I am trying to figure out is how I can set the default 'Save As File name when the Save As dialog comes up that gets generated from the Response.AppendHeader in the content-disposition ?
Below is my code that I have.
protected
void btnExportExcel_Click(object sender,
EventArgs e)
{
// CurrView is populated from a Session variable
string fname =
"e:\data\customapps\fieldsalesreports\mydata\" + CurrView +

I have a web app which displays some data in a GridView. This GridView is populated with a method called BindGrid. The user selectes one or more rows from the grid, then clicks the Process button. What needs to happen is that the selected rows are assembled into a CSV file which is downloaded to the browser, then the database is updated to reflect which rows were selected, and the grid is refreshed so the previously selected rows are no longer displayed. This all sort of works, except...
My code is below, which is very similar to lots of snippets found in this forum.
The problem is that if I uncomment Response.End(), or replace it with ApplicationInstance.CompleteRequest, it all works great except none of the code after Response.End() executes, and so the log entry is not made and the grid is not refreshed.
If I comment Response.End(), as in the snippet below, the code following does run, including the log entry and the call to BindGrid. (I know that because log entries inside BindGrid are made.) However, the page does not refresh. If I press F5 to refresh the page, it redraws correctly refreshed.
So the question is, how do I refresh the page after downloading the file?
I have tried calling both Response.Redirect and Server.Transfer after BindGrid
For what it is worth, I am using IE7.

I am working on a http based (NOT Secure) Web Application. In this, I have provided a provision to add some appointment to the Client's outlook calendar. I am creating the .vcs file dynamically when clicked on a hyperlink. The code of generating .VCS file is:
string calendarFormat = GetVCSFormat();
Response.ContentType = "text/calendar";
Response.AppendHeader("content-disposition", "attachment; filename=MyCalendar.vcs");
Response.Write(calendarFormat);
Response.End();
It is working fine in all browsers except IE. It is giving me following error:Internet Explorer cannot download GenerateAppointment.aspx from server. Internet Explorer was not able to open this Internet site. The requested site is either unavailable or cannot be found.

I'm trying to write come code for users to download files, but the files are located above the webroot (e.g. c:downloads)
I've found some code online that allows me to download a file via a url parameter/argument which is perfect, but the files need to be located within the website structure.
<%@ Page language="vb" runat="server" explicit="true" strict="true" %><script language="vb" runat="server">Sub Page_Load(Sender As Object, E As EventArgs)Dim strRequest As String = Request.QueryString("file") '-- if something was passed to the file querystringIf strRequest <> "" Then 'get absolute path of the fileDim path As String = Server.MapPath(strRequest) 'get file object as FileInfoDim file As System.IO.FileInfo = New System.IO.FileInfo(path) '-- if the file exists on the serverIf file.Exists Then 'set appropriate headersResponse.Clear()Response.AddHeader("Content-Disposition", "attachment; filename=" & file.Name)Response.AddHeader("Content-Length", file.Length.ToString())Response.ContentType = "application/octet-stream"Response.WriteFile(file.FullName)Response.End 'if file does not existElseResponse.Write("This file does not exist.")End If 'nothing in the URL as HTTP GETElseResponse.Write("Please provide a file to download.")End IfEnd Sub</script>
Source: http://www.xefteri.com/articles/show.cfm?id=8
how this can be modified so that it can access files outside the webroot?
I'd like it so that I can create an href like: <a href="download.aspx?file=test.pdf">Download File</a> and then the code will download the file from c:downloads est.pdf

I have VB code that parses XML data from a webpage. Up until 2 days ago the XML data could be viewed right on the page and I could just grab the HTML source code to get the information. Now they have changed the page to a link button to download the XML file.
The problem is that when I click on the XML link I get the 'File Download Prompt' which asks me to run or save the file. I figured I could just save the file to temp directory and then open it up to parse it in my VB app but I can't figure out how to grab the file from the browser in my application.
