I have a form with a few fields that the user has to fill, and then an upload field that allows the user to upload their article (I haven't added the code to check for file size and format yet; trying to get it to save first!)
For some reason, the click event of the button doesn't run, and I don't get any exceptions or such. Here's the .aspx file:
<%@ Page Language="C#" AutoEventWireup="true" title="Submit an Article" CodeFile="SubmitArticle.aspx.cs" Inherits="SubmitArticle" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

Until the Dec 29th my website was working fine. Then My fileupload problems started happening. My fileupload page would simply quit and say the page can not be found. I maximized all my timeout settings and that did not work. I called my hosting company and apparently they have no problem using my page to upload files from their geographical area. So then I concluded it might be a network problem. I ran a trace route and could not really figure out where the problem was. So, I have no idea what is going on. Is it possible that my site is being blocked by some black list out there somewhere?
I have a simple file input field that utilizes a File.Copy routine to move the file from the local store to the server. This part of the application works fine in staging but in production I had to establish a work around in order to get it to work. I have the users do a Save As on the file they want to upload and then slightly change the name of the file and then it will upload. I do not have to do this in staging with the same file in order for it to work. I am racking my brain as to whether this is a permissions issue or code issue or what.
i have a fileUpload in my web page but it's not supporting all files eg:
when i browse xls file it's working for small size files but when i go for a little bigger files let's say 50-60k it won't work and will give me an offline web page, i have tried the input HTML on server mode and still having the same problem.
To enable the details of this specific error message to be viewable on remote machines, please create a <customErrors> tag within a "web.config" configuration file located in the root directory of the current web application. This <customErrors> tag should then have its "mode" attribute set to "Off".).aspx
I have a file upload control and a submit button(). when file upload haven't any value(no file selected), button is working. when it has selected any file to be uploaded its not enter to the event handler where i have put a breakpoint
I'm trying to use below simple code for ajax postback. With file upload, neither javascript the "function startRequest" ever triggers, the file control shows null value somemore.Earlier I had Update progress which didn't work with file upload ever so I removed it. Now I just want to disable the button as the file is uploaded and its inputs are processed in the background. Once the response comes back, the "submit" button is re-enabled.But the file-upload with Updatepanel doesn't work at all. What am I doing wrong,
I do not want to change the default settings for file upload, 4Mb is more than enough for the project I'm working on. After quite a bit of searching I found two approaches that were purported to work but neither one is preventing the "Maximum request length exceeded" error. The first approach[see ref. #1 below] performs validation with a custom validator and in code behind on the page that contains the FileUpload control. It doesn't work. The second approach [see ref #2 below] performs validation in the Application_BeginRequest event in Global.asax. The author stated that validation must be handled by this event. Quoting: "The way to get past is to use your Application_BeginRequest event to handle the problem.. This event takes place for each request to your application BEFORE the data has been completely uploaded. Here you can check for the content length of the request and then redirect to the some error page or the same page with some value in session or query string so that the page can show appropriate message to the user." Here is my code from Golbal.asax based on the above. As noted, this approach doesn't work either.
protected void Application_BeginRequest(object sender, EventArgs e) { const int maxFileSize = 4 * 1000000; // Slightly less than 4Mb if (Request.ContentLength > maxFileSize) { Response.Redirect("~/FileUploadError.aspx"); } }
One comment by a reader of the Global.asax approach was that the value returned by Request.Content.Length would include everything on the page, i.e. viewstate, image and text content, etc. I suppose one work-around would be to set the limit higher in web.config but validate for max. file size in code behind, but that seems kind of silly because I'm manipulating the uploaded files (images) to reduce the size anyway; storage space isn't the issue, performance is. Has anyone managed to solve this poblem?
Iam using a file upload control for uploading files in my asp.net application. iam using the following code to impersonate the users who do not have permission for the files to upload. The code works fine for all the files, but it is not working for the files which are in desktop.
I have a file upload control, in edit template and footer template and I want to store its path in database, but I am unable to get the path of from File upload control.
I have a web application which has 2 different versions deployed. 1 is an ASP.Net web forms version and the other is an ASP.Net MVC version
I have a File Upload page which dynamically creates a directory folder for the target location of the file to be uploaded to.
The application is using Forms Authentication for outside users and Integrated Windows Authentication for inside the network users.
I have an issue where a user can upload a file in the ASP.Net Web Forms version fine. But when the same user tries to upload the file in the MVC version the user gets a File.IO permission error.
Here's the kicker: I can upload the same file in both versions. The user is in a remote location but I believe they're still inside the network because they can work on the other parts of the application just fine.
Possible clues: In the event log there's an info that says Event code:4005 Forms authentication failed for the request. Reason: Ticket supplied was invalid.
What would be your initial thoughts on why this is happening?
iam using masterpage and ajax update panel, i have child page called fileupload.aspx,i try to upload the file but its not working , can i use updatepanel in child page.
I have a webpage with an asp.net 2.0 upload file control, it works on Windows, but not in the IPad/IPhone, the textbox of the upload control has disappeared, and the button of the upload control is disabled.
I want to upload files to the web servers from the client machines.
Can i upload a file on a network share folder using file upload control?
I would like to create a share folder on a file server sitting next to the web server. If i upload the file from the network share folder instead of uploading it from the client machine does it make any difference?
Will the file be stored in a temporary location before copying to the final destination? Where will be the file stored in this case of uploading it from share folder?
I have 3 upload controls ,one listbox and two button controls in page. One button control named Attach has the code to add the files to listbox form 3rd file upload control and the 2nd button control named Save has the code to save the files of 1st and 2nd file upload controls in application folder and items of listbox to database.
The issue is couldn't maintain the state of 1st and 2nd file upload controls after browsing the files to file upload controls and clicking on Attach button control to add file name to listbox which was browsed by 3rd file upload control.So i placed the 3rd file upload control, Attach button and listbox in update panel but its not working. My requirement is when clicked on save button files of 1st and 2nd file upload controls in application folder and items of listbox to database, but 1st and 2nd file upload controls will loose the files as soon as Attach button is clicked to add filename of 3rd fileupload control to listbox.
