IE Bugs When Writing JSON Via An ASPX Response

Jun 17, 2010

I have an ASPX page that I am using to write JSON. It works great in Firefox and Chrome, but when I try and use it in IE 8 it gives me an "The XML page cannot be displayed" error instead of allowing jQuery to load the JSON being written by the response. Here is what my code looks like:

protected override void OnLoad(EventArgs e)
Response.ContentType = "application/json";
Response.Write(string.Format("[ {{ "Foo": "{0}", "bar": "{1}" }} ]", "Foo Content", "Bar Content"));

Cannot Use Response.Write In <head> Section Of Aspx Page?

Feb 18, 2010

I'm trying to use the Response.Write() method to dynamically insert content in the < head > section of an aspx page. I need to inject a string value from a property on a code-behind object which is a link to my CSS file. However, it is not being processed properly at run time. The object is public on the class and is hydrated in the Page_Load() event. Down in the body of the page I can successfully inject other properties from the Corpoartion object with no problem at all.Why does this not work in the < head > section?This is the part that does not expand correctly:

<link href="<%= Corporation.PageStyleSheet %>" rel="stylesheet" type="text/css" />

Here is the entire < head > section:

<head runat="server">
<link href="<%= Corporation.PageStyleSheet %>" rel="stylesheet" type="text/css" />

Changing Response Type In Aspx Page Breaks In IIS7?

Mar 3, 2010

I have a custom implementation of Application_PreRequestHandlerExecute which is applying a deflate/gzip filter to the response. However, on IIS7, this is failing on my "script generator" pages. These aspx pages take in Query String values and return a custom bit of script, changing the response type to text/javascript. I think it is failing because of the way iis7 uses mime types, but I'm unsure how to fix it short of turning all compressio off.

.net - Session Variables Clearing On Response.redirect ('page.aspx",false)

Mar 1, 2010

I have an webforms app that loses it's session variables on response.redirect. I've read Bertrand Le Roy's blog about this and still can't get it to work. The page works in production. However, when I try in the VS2k8 IDE, the session variables are there right before response.redirect and on the first line of the next page, the variables are nothing. I've confirmed the session id is the same so I'm not skipping sessions. The target page is relative so the web server doesn't think we're changing sites (as confirmed by the sessionid).

Response.Redirect("menu.aspx", False)

JQuery :: XmlHttpRequest Sent Though ClientValidation Failed?

Jan 12, 2011

On "submitForms" click the fucntion "submitTest" is invoked. From jQuery documantation "submitHandler" would be called if form is VALID. So, the validation works and "submitHandler" is NOT invoked if form is INVALID. BUT, the XmlHttpRequest is sent anyway, though "submitHandler" isn't invoked.

<% using (Ajax.BeginForm("FormPost", "Customer", null, new AjaxOptions() { HttpMethod = "POST" }, new { @class = "form-container" })) { %> <%: Html.TextAreaFor(m => m.Name, new { width = 440, height = 100 })%> <input type="button" value="submitForms" /> <% }%><script type="text/javascript">function submitTest(){var forms = $(".form-container");forms.each(function (index, form) { $(form).validate({ submitHandler: function (form) { $.ajax( { .... }); } });});forms.each(function (index, form) { $(form).submit();});}</script>

Javascript - XmlHttpRequest Sent Though ClientValidation Failed?

Jan 12, 2011

I have many AJAX forms on the page and on button click I need to submit them all. Regular **forms.each(function (index, form) { $(form).submit();} won't work for me because in this way ONLY the last form will be submitted eventually. Therefore, I need submit them via $.ajax(...). But I want to enable submit ONLY and ONLY if form is VALID On "submitForms" click the fucntion "submitTest" is invoked.

Remove Cookie From XMLHttpRequest Object?

Jun 23, 2010

I am making an ajax call with jquery like:

url: "path/to/webservice.asmx"
beforeSend: function(xmlHTTPRequest) {
//modify headers here
//remove cookies
success: function() {

What I would like to do in the beforeSend function is take the incoming xmlHTTPRequest variable that is set and modify the headers to remove the cookie object that is in there, so in the call to my web service, it does not renew forms authentication in

Avoiding Cookies While Requesting Static Content?

May 31, 2010

I just did an audit of one of my web application page (built using ASP.Net and running on development server) using Google chrome's developer tool. One particular warning caught my eyes:

Serve static content from a cookieless domain (5)!

Here is my screen shot [URL] as well. I would like to know is it possible to avoid cookies for these kind of requests. I see that there is no cookie requests for javascript files as well. I it possible to avoid cookies in the header for these files as well? and why didn't the browser attach cookies for javascript files and attach for CSS and image?

We have a Web Application (WebApplication A) which is in place and serving fine, we are working on another WebApplication which will use the Engine of Existing Web Application (WebApplication B) to some extent.

Problem: WebApplication A responds when a http request is made for a resource, like LatestPost.aspx, which passes it down to relevant class / Module like FrontManager.cs. I want to know how can we access that Module / class (FrontManager.cs) from WebApplication B, without requesting a Web Page ?

Soap - Is There Any Way To Get The Requesting User's ID In A Web Service Method

Apr 30, 2010

I know this probably isn't possible, but I would like to be able to get the Request user ID from within an ASP.NET web service method. So far, I've tried User.Identity.Name, Context.Request.LogonUserIdentity.Name, Request.ServerVariables["AUTH_USER"] and Request.ServerVariables["LOGON_USER"]. Am I tilting at windmills here, or is there something super simple that I'm missing?

Security :: Set And Send Back To Requesting Page?

May 6, 2010

I made a custom MembershipProvider to work with Oracle and my own database schema. I also have my own layout of controls and am not using the built in ASP log in controls. I don't even want to use it templatized. Reason being is that I don't want to show all those controls on one page.I want on the top of every page on the siteUsername textbox Password textbox Sign In button Register buttonI created a register form as the first step of trying out my provider. Everything has landed in the database correctly.Now my problem is that when a user clicks the Register button from any page, I need to note what page is requesting the registration form and then send them back when registration is complete. The built in controls seem to automate this behavior, but I do not know how to do it myself.So question is: How can I program the site to remember what page a user came from when clicking a register button, then send the user back when registration is completed?

Invoking WebMethods With XmlHttpRequest And Pure JavaScript?

Jun 22, 2010

I have what should be a relatively simple task that's frankly got me stumped. I've researched it until my brain is fried, and now I'm puntingHere's the scenario:I have an ASPX page (Q2.aspx) that is decorated with the WebService,WebServiceBinding, and ScriptService attributes. That page contains a method, GetAllContacts, that is decorated with the WebMethodattribute and returns a string containing JSON data. (For what it's worth, the pageitself contains no other controls or functionality.)I have an HTML page that contains JavaScript which uses the XmlHttpRequestobject to invoke the GetAllContacts WebMethod on the ASPX page and transformthe JSON data into an HTML table. I have verified that my Web.Config file contains the appropriate protocol handlersfor HttpGet and HttpPut in the WebServices section under System.Web.webServices.
I have verified that my Web.Config file contains the ScriptModule entry under theSystem.webServer.modules section, and that it matches the appropriate documentation.

However, when I view the HTML page in a browser, the following occur:The web request goes through, but the results are for the unprocessed HTML from the ASPX page.The GetAllContacts method is never invoked, as evidenced by setting a breakpoint in its code.The code to invoke the Web service, however, is invoked, and the JavaScript callbackfunction that is invoked upon request completion is properly invoked.

It appears that the JavaScript code is largely set up correctly, but for some reason that is completely escaping me at this point, the HTML page will simply not execute the WebMethod on the ASPX page, and simply returns the page as though it were a plain HTML GET request. Clearly, an HTML document can't be evaluated by JavaScript's eval function, which brings me to my problem. (Also note that the JSON data appears nowhere in the HTML that's returned.)I am, frankly, baffled. I've looked at dozens of Microsoft articles, StackOverflow posts, CodeProject articles, and who knows what else. My code looks like it's okay. But I know better. I'm missing something simple, stupid, and obvious. I just need someone to point it out to me.Below you'll find the ASPX page code and the HTML code, in the hope that they'll shed some light.ASPX Code

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Q2.aspx.cs" Inherits="Satuit.Q2" enablesessionstate="False" %>

C# - Use XMLHttpRequest To Execute A SQL Query And Return The Results?

Feb 9, 2011

I'm building a web app for my company that will run a query every few seconds against SQL Server, and the data that it returns is which database is restoring and how much % complete it is. I have the query already set up and it works fine.

What I want to do is on my Web Form, have a "div" element that will contain the % complete of a database restore, and have it update every few seconds using the JavaScript timer object:

setInterval(function, interval)

I figure I would need to use XMLHttpRequest to send the request to the web server which will run the SQL query. Am I on the right track? How would I even start to do this?

My SQL query is below:

Use master
Select der.session_id, der.command, der.status, der.percent_complete, *
From sys.dm_exec_requests as der
Where percent_complete > 0

XMLHttpRequest - Send JSON From Mozilla Addon To Page

Apr 16, 2010

I am trying to send JSON from my mozilla addon to my page.

var myJSONObject = {"userName": una,"password": pass};
request = new XMLHttpRequest();"GET","" + myJSONObject,true, null, null);

on my .net page I have tried several ways of doing it but not able to find the best way to serialize and deserialize the code. All I need is to send the json data back n forth and parse it on C# n javascript.

I have tried DataContractJsonSerializer, JavaScriptSerilizer among many other things. But not able to make any of it work. With the JavaScriptSerilizer, It does deserilize it if it takes an argument from the browser for e.g. If I open up the browser and paste something like [URL]} it does deserilize and return me individual values, but it does work when I do an XMLHTTPRequest (as above) from my mozilla addon.

Code used to perform the http POST....
