AJAX :: Loading Javascript File Based On Browser Version And Type?
Jul 7, 2010
I have some javascript files for each browser version and for different browsers. I want to include this files in script tag of script manager. Is it will detect these files and load based on browser version? Is there is best way to handle this scenario declaratively in markup insted of codebehind?If not declaratively how in code behind?
I'm try to get my site to detect what browser someone is using to ensure they're using one that is compliant with our site. Everything works, except Firefox seems to post the wrong version in the Request.Browser variables.I'm on Firefox 3.6.10, but Request.Browser shows Mozilla 1.9.2.10. It's correct in the HTTP_USER_AGENT string:
Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.2.10) Gecko/20100914 YFF35 Firefox/3.6.10 ( .NET CLR 3.5.30729)
Is there a way to detect it better without having to parse through the HTTP_USER_AGENT string?
I'm working on an ASP.NET web application for our corporate intranet users. I have a form where a user should provide a path to the file on the local network (something like "localServersomeFoldersomeFile.ext") without uploading the actual file. The issue is that users don't want to type the whole file path and want to use some kind of visual browse dialog.
The standard HTML <input type=file> element allows to browse for a file, but most of the browsers (except for IE) don't allow to access file's full path, so I think it should be done by some external component like Silverlight, Flash, Java applet etc. I tried to do it with Silverlight, but I'm getting a SecurityException when trying to access file's full path using Silverlight's OpenFileDialog class. This java applet [URL] seems to do something similar to what I'm looking for, but it's focused on uploading files - I only need to be able to get file's full path and pass it to the server as a string.
I recently ran yslow on a page i have (master paged etc) and it returned that there were far too many javascript files included (most of which I haven't added).
I guess my question is that given i have v1.0.20229.0 of the toolkit.dll (over .net 2)
I'm wondering if subsequent releases have fixes for this sort of thing?
function btn_AddToList_Click() { var filePath = document.getElementById("FileUpload").value; if(filePath.length > 0) { var opt = new Option(filePath,filePath); var listBox = document.getElementById("ListBox"); listBox.options[listBox.options.length] = opt; } }
I would like to restrict what they see in the file upload dialog, which is set to "All Files" by default. I understand how to validate that they only uploaded a certain file type, that is not the question here. I would just like to know how to default the file type in the file selection dialog.
Is there any way to change this to "PNG only" or "*.png"?This is using AsyncFileUpload in the ASP.NET AJAX Control Toolkit.
i would like to use script manager and update panel in different domain to accommodate an other domain web site inside a iframe, but it prompts me a an error alert box (An error has occurred in this dialog. Error: 54 Permission Denied), may i know why?
Is that any solution to solve the problem?
Secondly, in the different domain, the JavaScript function EndRequest(sender, args) is not work after finish the loading whereas the InitializeRequest(sender, args) is work. May i know why?
I am developing full ajax web app. So I need to develop google crawlable app, also I must create snapshot for googlebot.Do you know headless browser works with javascript and ajax for ASP.NET ?I found XBrowser but right now it hasn't JavaScript support.

I embed wmp, swf, and qt in a modalpopupextender. Some of the video files take a long time to load so a given player's window stays empty for too long. I think I should be able to have the player hidden initially and display an animated gif in the modalpopupextender and then when the video files completes loading I'd hide the gif and show the player (or simply manipulate the corresponding z-indexes).
I am in charge of converting an ASP.NET web application into fully AJAX based application. I know Javascript and Jquery very well.
Initially I thought to point every anchor tag's click event to JS function and to call stuff via ajax and to populate the body and so on. I encountered a problem when it came to ASP.NET Form on every page and when there was need to make a post-back. I decided to point every Form tag's onSubmit event to a JS function to post stuff using ajax and to get results and I got to know this is not possible with ASP.NET as every time where is a button click, there will be post back so it's hard to let page know what button was clicked.
I then decided to use ASP.NET built-in AJAX controls to use with Forms which is pretty easy and worked like the way they should. Now I am stuck with the question of which I should go with?I like to be JS way because it's more customizable than AJAX.NET.
my application is running in visual studio 2005, i used ajax control toolkit for .Net framework 2.0.but now i want to use ajaxcontroltoolkit latest version which is for .net framework 3.5 in my application which is running on .net framework 2.0 and visual studio 2005.how to integrate or use ajaxcontrol toolkit ?because i have some functionality like there is one file upload control and when click button it will take 2 to 3 min for upload so i need progress bar with loading gif file.because of asynchronous postback fileupload control has not file.so i must assign postback trigger to button if i assign postback trigger to button than loading gif or progress bar not working.so i want to use AsynchFileUpload control of newly release toolkit.
is there any way to do it? or any other way.my client also not want to switch over it's application from 2005 to 2008.My code is below
I have a solution I'm working on in VS2010 Professional, using ASP.NET 4.0 with the AJAX Toolkit.This has been working fine, but when I started it up today, I got the runtime exception shown above. This exception occurs on any page with a control from the toolkit.Sometimes when I load a page, I get an exception "Could not load file or assembly 'System.Windows, Version=2.0.5.0, Culture=neutral, ublicKeyToken=7cec85d7bea7798e' or one of its dependencies. The system cannot find the file specified." If I then reload the page (without making any changes), I then get the exception shown in the subject line.I tried dragging an AJAX Toolkit control from the toolbox onto a page, and then deleting it, and that worked - once. The next time I tried the page (or any other), I got the exception again. Dragging a control out didn't help this time.
I created a very simple webService using the VS2008 template. i am planning to use Ajax call for the webService.when i try to open my webservice in IE browser using following link to see the Javascript proxy, it return blank page.[URL]
We have an ASP.NET web application and it's hosted using IIS 6.0, in the app we have these several javascript and css files located in a folder, and for performance sake (according to YSlow) we set the folder content expiration header to 1 year. Everything worked just fine until recently when we deployed the latest build to the server, in which we had made some changes to those javascript and css files. For some reason after the deployment some of our end users don't see the latest changes when they connected to the app, even after they cleared the cache in IE. We have also restarted the IIS on the server and the problem still remained. When I went into the IE Temporary Internet Files folder on one of these machines I saw the files were still the older version and not the latest one, I had to manually delete the files from the Temporary Internet Files folder then they were able to see the latest changes. I'm baffled by this, how come only some users who couldn't see the changes but some others do (without having to do anything by the way), and how do I make sure that for future releases we won't have to do anything like what did (manually deleting the cached files)? For now I disabled the Content Expiration option in IIS for these files but I would like to know if there is a way that I can enable the content expiration (to help performance) but at the same time making sure when the files are updated, the latest version will be used for the end user (instead of the cached version)?
as all we know that we can create very simple chat using ajax timer & web service , it runs well for few users .
i want to leaverage same idea for site where 5000+ users will be there in chat room , messages are stored in queue hold in memory * dispatched as user request that is through java script timers calling page method or service ,
how well it will perform ? i know GTalk implements XMPP protocol(jabber) for the web chat seems it will be difficult to got XMPP way ?
