i'm just getting started with asp.net and ajax. My question is : is it possible to make an ajax request and simulate the server response in the code behind. in other words can the request be sent to the code behind of the same page? if it's possible haw can i perform this ?

For example, I have three UpdatePanels on the page. I click a button, and I get pretty long response, that contains all the data for the three UpdatePanels, the viewstate string.
I want to optimize my query and receive response like "ok" or "not ok". How can I do that?
When the user tries to upload a file with a size more than 4 MB, the AsyncFileUpload control gives a Confirmation alert (with "OK"/"Cancel" button) with the following message "Server Response error: Maximum Request Lengh Exceeded". But when the User clicks the "OK" button a new window popups and shows the server error and on clicking the cancel button the AsyncFileUpload background color turns red. Here I am not sure why the control is showing a Confirmation alert instead of a simple alert message. Is it possible to change the Confirmation alert with the simple alert message? Basically I don't want the popup window to show the server error as it is happening currently. Also, is there a better way to handle the file size error and show apporiate error message to the users?

jQuery ajax request response is empty in Internet Explorer?
Hoping someone can point me to a solution, haven't been able to find one yet.
I'm using the standard way for send HttpWebRequest
[Code]....
As you can see from Fiddler/SOAPUI it does return the SOAP fault, however using HttpWebRequest i can't capture the response.
Returning 500 triggers my exception handling and Capturing the WebException doesn't expose the response.
Does anyone know how to capture this response xml in the case of 500 Internal Server Errors.
Is it at all possible to inject a request into IIS for a page, have IIS and ASP.Net handle it as normal, but get the response as html handed back to me programmatically?
Yes, I know that I could connect to port 80 using WebRequest and WebResponse, but that becomes difficult if you are accessing the IIS server from the same physical machine (loopback security controls et al).
Basically, I want to inject the request (eg for [URL]) between the points at which IIS would normally talk to the browser, and the point at which it would route it to the correct ASP.Net application, and get a response back from IIS between the points at which ASP.Net/IIS applies the httpfilters and hands the html back to the browser.
I'm predominantly working with IIS7 so if there is a solution that works just for IIS7 then thats not an issue.
This is so frustrating to me. I'm doing this via standard .NET 2.0+ web services (not WCF). My application is in .NET 3.5 but I'm just adding a service reference. I've not done any SOAP WSDL sending before. I've used NVP which to me seems much more error prone and burdensome because you have to create all the wrappers yourself and if any of that third party API changes, it breaks your code. I have not a clue how to make a call using the latest PayPal WSDL. I added the service reference and I see proxy classes such as [className]Request and [className]Response but how do you actually make the CALL and send the request over the wire?
I see people have used the outdated (.NET 1.1) PayPal SDK. We do not want to use an SDK just to send a request. Isn't it much easier nowdays in .NET when using any SOAP API to invoke the request? People for example using PayPal are relying on a caller class from that SDK but again it's way, way outdated. So onto today, .NET 2.0+, I thought that you don't need all that plumbing anymore?
How would I do this? I see no good documentation on the net period on .NET 2.0 or 3.5 web services especially SOAP and it's frustrating. Sure add the service reference, use the WSDL and proxy generated class wrappers but outside this HOW to make a request is impossible to find. I'm seeing legacy ways of doing this in .NET and then I hear this is all done under the covers for you in .NET..I guess that must be .NET 2.0+ ?? Is it as simple as just making the proxy class method calls and .NET under the covers takes care of the plumbing to actually send the request over Http unlike .NET 1.1 where you had to do all the plumbing yourself?
I have a page that contains a user control. Can i make an ajax request directly to the control? I know I can make an ajax request to .aspx or .ashx; however, is it possible to go direct to the .ascx?

View 3 RepliesI have an ASP.NET project (VS2008 on Windows 7 with either webforms, MVC1, or MVC2 -- all the same result for me) which is just the File->New hello world web project. It's using the default ASP.NET development server, and when I start the server with F5, the browser never connects and I get a timeout. I tried to debug this by telnetting to the development server's port while it was running, and I got the same result:
C:Usersfarmercs>telnet localhost 54752 Connecting To localhost...Could not open connection to the host, on port 54752: Connect failed I can see in the system tray that the server thinks it's running, and a netstat -a -n command shows that there is indeed an active TCP listener on that port.
This worked in the not-too-distant past, and I could work on web projects using the development server. One thing that has changed since then was that I installed the Microsoft Loopback Adapter to accommodate a local development Oracle installation. I'm not sure this is the problem, but it seems a likely culprit.
I also tried to hit the port using the server name itself (http://mycomputername:54752) but with the same result. So, what could be blocking me from connecting? And if it's the loopback, then what is a good way for me to retain my ability to connect to my development Oracle server while still being able to use the ASP.NET development server?
I want to provide status updates during a long-running task on an ASP.NET WebForms page with AJAX.Is there a way to get the ScriptManager to execute and process a script for a web service request concurrently with an async postback? I have a script on the page that makes a web service request. It runs on page load and periodically using setInterval(). It's running correctly before the async postback is initiated, but it stops running during the async postback, and doesn't run again until after the async postback completes.
View 3 RepliesWhen I use WatiN to go to a specific web page, how can I fake the HTTP referrer with a query string (i.e. request is from google search with query string q=search_term)? So I can verify that the response header has the 301 redirect for specific referrer URL.
View 2 Replies we have an ASP.net web application running on IIS7. We have multiple users, but we don't always know their password. Here's what we'd like to be able to do:
Login as some sort of administrator, be presented with our current list of users, click some sort of "Run as John Doe user", at which point we'd be able to see the application (or certain pages) as that user.We're looking to do this in a support/debugging capacity. I've looked into ASP.net's Impersonation, but that doesn't seem to apply here.
I need to request a series of pages and want to do from the server code as if you were doing with Ajax, I can do?,
View 2 RepliesSo in my website, I use jquery to fetch data through ajax. AS part of the ajax response, some of the javascript code comes as well which is executed. The problem is how to debug this javascript in firebug or other tools. This is my experience so far: putting debugger; doesn't work For some javascript, can't set the breakpoint as that script is not yet loaded. even if this new javascript calls some other function thats already loaded (i.e. i can see it in firebug and set a breakpoint), that breakpoint on that function is still not triggered
However, the javascript does executes normally and even things like console.log works but cant seem to debug it.
I have a drop down in an ASP.NET page. Whenever the value of the drop down changes an ASP.NET AJAX request is made to the server. I also attached a jQuery "change" event handler to that list to execute some code when the value is changed. So, probably two different event handlers are being attached to the same drop down, and it's causing some problems, i.e., sometimes wrong drop down values are sent to the server. I don't know why is this happening but I think attaching two different event handlers to a same drop down may be the reason.
Can anyone tell me what is the problem here? If what I guessed is true, then is there any other way to execute some custom javascript code before asp.net AJAX request is sent ?
I am developing an asp.net web application and stand on jQuery plug-ins for any aspects of my Interface. But unfortunately I have to use AJAX only for its UpdatePanel to enable partial rendering. Is there any way to use jQuery for partial rendering and act such an UpdatePanel?
View 2 RepliesI know this is strange, and probably considered bad design. I need to simulate the clicking of an actual button on my asp page. I do not need the button's on_click event sub/code to execute. The issue here is that I want to trigger the ConfirmButtonExtender associated with that button. The ConfirmButtonExtender, by design, executes before the Click event code.
So to be clear, I need to actually "click" the button. What the button does is irrelevant (in fact the button is invisible and has no code). I simply need to trigger the button's ConfirmButtonExtender, not the code behind the actual clicking of the button. Like this..
Protected Sub Button1_Click(.....) Handles Button1.Click
Somehow click invisible_button (not call the Click() event, but actually "click" the button)
End Sub
----Long, convoluted details------
I have fields on a page that require user input. When the user hits submit, I want to display a confirmation dialog with the data of those fields.
To do this, I originally added a ConfirmButtonExtender to the "Submit" button (just a regular ASP button). The problem appears because the ConfirmButtonExtender executes before the OnClick event of the submit button.
During my OnClick even I took the data, populated it into a confirm textbox (which is inside a ModalPopUpExtender). I originally then used the MPE.Show() (still in the onClick event) to display my conformation textbox.
However ,the .Show() function doesn't halt code execution (which is needed, since this is a confirmation dialog). So as a result, I created an invisible button.
This invisible button now has the ConfirmButtonExtender added to it, which will display my MPE/Confirm Dialog. When the user hits "Submit", the click routine is called, all the data is stored and populated, and THEN I want to "click" the invisible button, triggering the ConfirmButtonExtender. That will halt code execution in my original Submit buttons click routine.
I can't seem to make the RCE work with the following code:

I need to simulate a proxy server to test mobile device c# application.
Is there a way to do this? how should I do this.
Why the ajax control is working slow when i upload to the server? such as the custom validator is slow response in the server, the modal popup box or loading is slow to response or close up after click the ok button. It work fast in the local server.
View 2 RepliesI am currently building an asp.net webforms application in ASP.NET C# using Visual studio 2008 and the Framework .NET 3.5.In my application main page, I use some javascript code to make AJAX calls to different handlers (.ashx files) in order to get some information.In this handlers définition (in the CodeBehind), I use the Oracle provider for .NET (Oracle.DataAccess.Client) to get the requested information from an Oracle database.The thing is, when I make a first call to one of these handlers, everything works just fine, but when the main page try to repeat the call in order to update the information requested, I encounter a problem.In fact, it appears that the different Oracle SQL request results that were made during the first call are still in memory and that the requests are not repeated correctly in order to obtain the updated information from the database. The application keeps the first results and this is these results that are sent back to the main page once again.I don't know how to force the handler to obtain new results and work with it instead of working with the previous results.In the handlers définition, the IsReusable methods are all set to false.I have called the Dispose() méthods of every Oracle object at the hand of the handlers définition and then the System.GC.Collect() méthod to force Garbage Collection. But this does not seem to be sufficient to be sure that nothing is kept in memory.
