JQuery :: How To Upload Files In Browser Cache To Get File Size On Client Side
Apr 1, 2011
My requirement is to get the file size in client side. there is no problem in FF but in IE you can't do that unless u r using an activeX object. So we thought of putting it in browser cache and reading the file size from there and when we post it to the server we will be taking it from the cache and send it to the server.
I have a async file upload control and I am doing client side validation for Image."OnClientuploadstarted" I am doing the client side validation.My validation is working fine but my problem is that the file upload control text box goes green (i.e file is loaded on the server) even if the validation fails which is I dont want.What I want is when the client side validation fails the file does not gets loaded on the server and the Async file upload textbox does not goes green.I have goggled but have not found a suitable solution.
When the user selects the list of files from a page and hit's download selected, then a post back happens to server and starts zipping on the server. This works great until we hit the timeout on the page ( which is default to 90 seconds ) and just returns the process to the page even though the backend process is still zipping. Is it possible to show the size of zip file when the file is being zipped instead of waiting till the end to provide the download link?
I would like to ask we select a file in our system and drag that file into browser, drop that file into particular location of the browser at that time the file is to upload.
Assume a simple aspx data entry page in which admin user can upload an image as well as some other data. They are stored in database and the next time admin visits that page to edit record, image data fetched and a preview generated and saved to disk (using GDI+) and the preview is shown in an image control.
This procedure works fine for the first time however if the image changes (a new one uploaded) the next time the page is surfed it shows previously uploaded image. I debugged the application and everything works correct. The new image data is in database and new preview is stored in Temp location however the page shows previous one. If I refresh the page it shows the new image preview. I should mention that preview is always saved to disk with one name (id of each record as the name).
I think that is because of IE and other browsers use client cache instead of loading images each time a page is surfed. I wonder if there is a way to force the client browser to refresh itself so the newly uploaded image is shown without user intervention.
Suppose I'm building a StackOverflow clone using webforms ASP.NET and jQuery. The Question page has a question, several answers, and comments under each. Requirements:Users can post new answers and comments, and edit existing ones, without postbacks. No UpdatePanels; the AJAX calls retrieve just the JSON they need, not HTML fragments. The page loads with all existing answers and comments in place (no javascript needs to run to read the page).
What I'm trying to figure out is how to do this without having to maintain two sets of markup (one that's bound on the client using some form of jQuery templating, and one that's bound on the server using traditional WebForms).
I have a website that i did some time ago now they request some new features and i did some changes in some javascript files, but when i publish the clients that use the IE have problems with cache so in they browser they have old version of javascript. How can i clear the client cache so when they visit website they use latest javascript files that i modify.
Have some problems with client side validation (using RequiredFieldValidator, RegularExpressionValidator, CustomValidator with client side validation logic). It seems that WebForm_DoPostBackWithOptions is not fired or causes unhandled exception that makes the form to do the postback regardless it's valid or not.
I tried using a ValidationSummary, hiding it if javascript is supported:
Every thing works fine on Chrome with disabled javascript on my laptop, but not on my Android phone. The problem is that on the phone Javascript is not disabled, it's enabled, and correctly hides the ValidationSummary, but does not perform client side validation for some reason that i can't understand (no developers tools on Android browser :(( ).This is very frustrating! :(
In asp.net website, i am using crystal report. My question is very generic i.e. How it is possible to display client side (browser) date and time?
Actually in my case our website is going to hosted at India, while that site is used by user's at SWEDEN.
Now the problem is that when user request for report then it is displaying server side date time because i have used PRINTTIME control of crystal report. But user should have date and time of their PC. because that time is basically a report generates date time.
downloading multiple files from the server side through the browser (i.e. Chrome) I've debbuged it the foreach iterates fine but it only downloads the first file.
Here's the code snippet:
FileInfo fInfo; SQLConnection = new SqlConnection(SQLConnectionString); foreach (CartItem CartProduct in Cart.Instance.Items) { [code].....
To my understanding the clinet side can only send data to the server either by get or post. so basically either through query string (get) or through body of the page (post).
So when we upload a file from client machine and send it to server, what exactly is happening behind the scenes? are we doing a post?
Im using a file uploader to upoad files to a folder used for upload.But the problem is this folder is a linux folder. I have made it a shared folder so that I can access from windows by samba. So, file transfer is successful when I'm using os but when I try to upload something from my websites uploader to this folder, this process is not successful. I have given all permissions to this folder.Don't know whats the problem.I have used both type of slashes for directory but still it is not successful.
I used the FileUpload and all is ok, I dont have problems, but I need put the path for the upload by default, in the load of the page, or java script,, but the FileUpload. values is only read , how i can change this value? when the user click in browse the choose file, make a filter by the path for default for example seacrh in c:d.... or the box Choose File how i can write the file name by default?
My client is uploading file more then 1 GB through application. I know i can only upload only 100mb using asp.net MVC application.
[code]....
i am getting error at byte[] data = new byte[st.Length]; because st.Length=1330768612 Error - "Exception of type 'System.OutOfMemoryException' was thrown."
Is there any way i can upload more then 1gb file?
Why we can define maxRequestLength= 0 - 2097151 in webconfig,
I want to check the selected file size BEFORE uploading a file with the asp fileupload component.I can not use activex because the solution have to works on each browser (firefox, Chrome, etc..)How can I do that ?
So we're having this problem. A user goes to upload a file, and if it's above 10MB, it just kind of times out the page, and clears, and no good error is thrown to describe what happened. Ideally, we would like to examine the file size when the user chooses the file they want to upload but I don't know if this is even possible. Our framework is built with ASP.NET, VB.NET, and Javascript (and ExtJS 3.0), and it runs in IE.
