I need to do multiple file uploads in my ASP.NET page. I also have to display a progress bar with the status of the file transfer. It should display an all file progress status bar separately and a total in a separate progress bar until the file upload has finished.

View 1 Repliesi'm developing a web application using asp.net 3.5 sp1, my issue is , i need to upload multiple files asynchronously.
for that i used the ajax control toolkit "async file upload", where i can only upload single file and cannot track the filenames after uploading, so i go for the "file uploaded ajax"
[URL]
when i started including the cascading dropdown in that page("mainpage.aspx") , an error occured in the page, ie; when i click add files of the "file upload ajax", the "file upload" control some times doesnot show, so i created another page("testpage.aspx") and included the "file upload" control in that page and created an iframe in the "mainpage.aspx" and call the "testpage.aspx", now it is working fine, but i was not able to track the filename, can i access the control inside that iframe from the "mainpage.aspx" ?
mainpage.aspx
<%@ Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit" TagPrefix="ajaxToolkit" %>
<form id="form1" runat="server" enctype="multipart/form-data">

when I select image and upload it and after that refresh page it again upload image that I upload with fileuoploadcontrol before...
I want when I upload image with fileuploadcontrol and refresh page it doesn't upload image again...
how I can do it?
I have a page currently setup to upload 1 image at a time, it uploaded the image, then creates a thumbnail for that image in the same directory. Client needs / wants to be able to upload a few more images at the same time. So i would like to see if i can use the existing code that works, but setup to upload a few more images and process them all to create the thumbnails.
I currently have a page that allows them to upload 5 images at a time and that works fine, but its just simple uploading the images, nothing else is happening at that moment.
Here is the code i am working with:

I recently embarked on the endeavor of creating my own asynchronous file upload components for ASP.NET. I took lessons learned form Darren Johnstone's FileUpload project and created an HttpModule for extracting the files from the submitted data.
I got everything working as it should in testing with VS 2008 using the Development Server. I even went so far during my testing to ensure that the request was being intercepted by the module before the files began uploading. After I was satisfied with things, I deployed the project to our web server (Win 2008 w/ IIS 7). I was horrified to learn that the controls were not functioning when deployed.
After some remote debugging, I found that the HttpApplication.AuthenticateRequest event (my location for hooking in to the process) was not being invoked until the files were completely uploaded.
On my current project I have to accept 2 Excel spreadsheets that will be uploaded by clients, process them and create a download package based on this information. This process includes extracting data from the sheets, updating our databases and building several PDF files for the download package. This takes between 15 seconds to 2 minutes to complete, depending on the complexity of the request. Naturally, I want to show some kind of processing indicator rather than just leaving the user hanging while the page loads.
Here's the problem: How to show this processing indicator.
I have to do a full postback to upload the files so this eliminates several nice AJAX indicator methods (sponsoring users rejected the AJAX toolkit async file upload, saying it was confusing to them). If I process on any of the page events during the postback, the page doesn't load until the lengthy process is completed so the browser/site looks 'hung'.
Basically, I need some ideas on how to display a 'building your download' graphic while the lengthy process is working that will also work with a full postback.
I'm using ASP.NET for file uploads, and I'm hitting a bit of a snag in that data sent by the client as multipart form data is read straight into RAM.
Obviously, this means maximum file upload size is limited to the available RAM on the machine, and even then is much smaller as soon as you have multiple simultaneous uploads.
Is it possible to get ASP.NET to write the data to a temporary file on the hard drive as it is recieved rather than reading into RAM?
I need a basic system that uploads a file to the server and stores the details in a database, with the ability to add/ edit/ delete whats there.
Most of the solutions I've seen have been far to indepth. I'd like something very simple so I can pick it apart and modify it.
I have a aspx called user-photo-upload.aspx and another aspx called get-photo.aspx. I set the Session["PhotoId"] in the page_load method of user-photo-upload.aspx.
If I visit the user-photo-upload.aspx through the browser normally, the session can be retrieved in get-photo.aspx. But if the flash uploads photo to the user-photo-upload.aspx page, I can't get the Session["PhotoId"] in get-photo.aspx.
I discover that the Session ID is different when visiting the page using browser normally or by flash. I don't know why flash uses another session.
For my project(in asp.net) i wrote near 1000 lines of c# code for one asp.net page.It includes so many functions.The problem is,it is going complicated while i am writing more codes on one page.How can i make multiple c# files for one asp.net page?? I tried by adding new class in VS2008.But calling a function from one file to other is making error(item is not present in current file).How can i do that??
View 6 RepliesI'm hoping that somebody cleverer than I am can explain what's happening with my file uploading and how to improve it.My website is used by vets to submit photographs of tumours in horses for examination by another vet and so it's important that the pictures uploaded are high quality, and therefore the file size is large. Since they might be uploading details of several tumours at a time with several photos of each uploading times can be very long.
I accept that upload speeds are generally slower than download speeds and I have put notes on the page to advise the user to be patient while the images upload. However, I've noticed when using Google Chrome, which displays a percentage-complete in the status bar when files are being uploaded that what seems to happen is that when the user selects a picture from the asyncfileupload control it then slowly counts to 100% as the image is uploaded. But when they then click on the 'Save' button which is when code-behind uploads the file to the web server and writes an entry in the database it again counts to 100% at the same, slow speed.
It's as if the file is being uploaded twice. It's as if the file is being uploaded twice, but I've only coded it to happen once, when the 'Save' button is pressed. The first upload must be some part of the way the asyncfileupload control works. So am I using it incorrectly? Should I somehow be using the inbuilt, automated upload to get the image to my server rather than in the code-behind of the 'Save' button?
One other piece of information which may be relevant is that at the point the picture is uploaded by the asyncfileupload control there is no associated record in the database for it to be linked to. When the 'Save' button is clicked a record for that tumour is created first, then then the image(s) is uploaded and an associated record created with the image filename, so using the automated uploading of the asyncfileupload control may not be possible for me as at that point there is no record to link the filename to. If that's the case can I disable it somehow?

instructor must add uploads to his page and students will be able to download this files,how i can do this?
Currently whenever a user uploads a file through our website, it gets put in a folder such as:
www.domain.com/Uploads/Docs/filename.doc
However, I'd like to move this to a subdomain such as:
uploads.domain.com/Docs/filename.doc
This is mainly because I'd like to keep the files uploaded by the user, totally seperate from the web app.
However, currently I use an ASP.NET FileUpload control to upload the files, by doing something like:
myFileUpload.SaveAs(Server.MapPath("/Uploads/Docs/filename.doc"))
How would I change this line of code to be able to upload to the subdomain easily?
In continuation to my previous research at this link : Security Risks or concerns with the use of FileUpload control of asp.net - how to Scan files during upload, also how to intimate user if file is virus affected and abort the operation. In addition to above, we have McAfee Antivirus installed on our servers. I heard that there is some APIS for this work for Symantac Antivirus but I am not sure about McAfee antivirus.
View 1 RepliesI was in need of exporting multiple tables in a DataSet to an Excel file with multiple sheets. I found a very good article in [URL].[URL] was able to successfully export each of my datatables in the dataset to excel worksheets. This solution worked for small number of rows. But when the data got larger I am consistently getting the system.outofmemoryexception. THis is because the code is using up the memory when creating excel.
Does anyone have another option to do the above?

I have an application that needs to render a page that will have multiple Radio Button Groups as well as multiple CheckBoxes. The desired layout is determined by a database table.
table structure:
PackageID uniqueidentifier
PackageName string
ItemName string
RadioGroupName string
ViewControlName string
This table defines a "Package". The "Package" can contain many different "Items" that require different controls used in the View. The "RadioGroupName" field is used to mark which RadioButtons should be grouped together. The "ViewControl" field marks which control should be used on the View to display the field. The query in my repository will return a result set such as
1 / "First Package" / "Item1" / "First Group" / "RadioButton"
2 / "First Package" / "Item2" / "First Group" / "RadioButton"
3 / "First Package" / "Item3" / "First Group" / "RadioButton"
4 / "First Package" / "Item4" / null / "CheckBox"
5 / "First Package" / "Item5" / null / "CheckBox"
6 / "First Package" / "Item6" / "Second Group" / "RadioButton"
7 / "First Package" / "Item7" / "Second Group" / "RadioButton"
8 / "First Package" / "Item8" / "Second Group" / "RadioButton"
Given this result set, I need to render the view as follows:
A RadioButton group with 3 options (Item1, Item2, Item3)
A CheckBox (Item4)
A CheckBox (Item5)
A RadioButton group with 3 options (Item6, Item7, Item8)
I have read that it is possible to use "if" conditions and looping structures inside the View. I have also read that this is a bad practice. Another issue I see is knowing which Item has been selected from each RadioButton group when I hit the Controller POST function. Previously I have built a page that has a single RadioButton group. My ViewModel was as follows:

I have created a Web Control in ASP for use in integrating with Telligent CommunityServer. The control is written in ASP with some 10 lines of C# backend for controlling visibility of the UI elements based on permissions, but I'd say 90% of the functionality is straight-up Javascript. The control works beautifully, until you drop two instances of the Control on the same page--since they reference the exact same Javascript functions, only one control works. How can I take this functionality that I have, this 1200 lines of Javascript, and make it so that each instance of the control can reference its each unique instance of Javascript?
View 2 RepliesI'm planning to make a page that has about 10 different pages for varying use, for example, stats, data entry, reports, logistics, audit, sales, promo, etc etc. I'm anticipating there will be many combinations as to what pages a user may have access to, for each page, a user ought to be authorized to either enter new data, edit data, print and/or just view.
My questions are :
1. can membership & roles be used, once user is logged in, to display links to all the areas of the web app he is allowed access to?
[code]....
2. besides having access to a particular page, a user should, as mentioned before, be authorized to either enter new, edit, print and/or just view data.
3. Is there a preferred/better method to handle this besides using membership & roles?

I calculate the total size of my PDF file which is mentioned below. What does this return? When I download a 2KB file, it returns a size of 2KB, which is correct. But when I download 2 files each of size 2KB, then the total size it returns is 2.16KB. Is that correct? Should it return 4KB?

I was referring muddasar's one of the article for the validation. Below is my code and i am trying to validate the file upload selected file format on the submit button. I have 4 upload control and fu1 is mandatory field and others are not mandatory fields. Though i need to validate all the four uploads if the files have been selected. My full sample code is below for easy testing,
<asp:FileUpload runat="server" ID="fu1" />
<asp:Label ID="lblMessage1" runat="server"></asp:Label>
<asp:FileUpload runat="server" ID="fu2" />
<asp:Label ID="lblMessage2" runat="server"></asp:Label>

I am doing slight mistake on the return to the main function. if i test indvidual function it works fine. whereas if i include the 4 functions in one function with the return statement, it's not validating. goes to to the server.
