C# - Connection Reset After Concurrent AJAX And Standard Form POST
Aug 24, 2010
Scenario:Own rolled jQuery Ajax post to validate an input field on unfocus Standard submit button for post on form
If I cause validation to fire and wait until I see it complete in firebug then click save all is fine. If however I leave a change in a field and then click the submit button directly (so both ajax and standard post happen at almost the same time) the request hangs in the browser before returning a 'connection reset'. If running in VS debug I see nothing unless I hit pause. I am then presented with the following callstack:
System.Web.dll!System.Web.Hosting.IIS7WorkerRequest.ReadEntityCoreSync(byte[] buffer, int offset, int size) + 0x23 bytes
System.Web.dll!System.Web.Hosting.IIS7WorkerRequest.ReadEntityBody(byte[] buffer, int size) + 0x18 bytes
System.Web.dll!System.Web.HttpRequest.GetEntireRawContent() + 0x2d4 bytes
System.Web.dll!System.Web.HttpRequest.GetMultipartContent() + 0x45 bytes
System.Web.dll!System.Web.HttpRequest.FillInFormCollection() + 0xad bytes
System.Web.dll!System.Web.HttpRequest.Form.get() + 0x45 bytes
System.Web.dll!System.Web.HttpRequest.HasForm.get() + 0x46 bytes
System.Web.dll!System.Web.UI.Page.GetCollectionBasedOnMethod(bool dontReturnNull) + 0x62 bytes
Background:ASP.NET 4 MVC 2 Web application with some legacy webforms pages (the page involved in both the ajax post and standard post is the same webforms page) running locally on Win7/IIS7.
I could potentially disable the submit button while the ajax validation fires. However even if I do that I'm intrigued to know what has caused this seemingly time based/concurrent request problem.

I am interested in finding difference betwen AJAX postback(Partial Postback) & Standard Web Form Postback(Full Postback).
1) What is the size of data submitted back to Server in AJAX & standard Postback(All Input elements are sent to Server here)
2) what is the size of Data that comes back when using Ajax Postback.
3) what is the difference in event Life cycle in AJAX & NON AJAX Post back
I need strong backing/proof as i will share it with other manager at my company

I have two Repeater controls, each hosted in a user control. Both user controls are contained in the same aspx page. Only one User Control is visible at any one time. The repeaters are comprised of checkboxes, and text boxes for user input.
The aspx page is configured with an Ajax ScriptManager; and contains several Ajax UpdatePanels. These UpdatePanels result in partial page post backs when text is changed in a textbox control in controls on the aspx page (this is not the behaviour for the Repeaters in the User Controls). Through use of several AsyncPostBackTriggers, various controls contained in the other UpdatePanels on the page have their content refreshed in response to the partial page post backs they are configured be notified about.
Depending on a radio button group selection, I set the visible property to true or false - as appropriate for the User control containing a repeater control. The Repeater control is then populated with data using databinding. All of this works.
However, when the Submit button is clicked, the Repeater control contains no data.
Given that I am not dynamically adding the Controls containing the Repeater controls (but using Visible true / false). I would have thought that the State of the fields and the data in the visible control would be preserved during the post back.
The User Controls are contained within the UpdatePanel that contains the Submit Button.
I have explicitly Enabled View state without any effect.
Am I correct in assuming that I should not have to do any explicit handling of data changes the user makes (via client side script and manipulation of an Data Structure Representing the Repeater Data); and the View State should maintain the data I need to access on the server when submitted?
I do not believe that it is the User Control visible state changes that are causing the issue because when the page is initially loaded on of the User controls is populated with dummy rows (so it displays).
I am suspicious that because the visible state of the controls is changed during partial page post back, that the Page View State ends up with no knowledge of the User Control and therefore cannot track its data (or changes).

Is there a way to force a non-secure form post to be secure? I understand there are ways to automatically resolve an http URL as an https URL but with form posts, is this type of redirection too late? Will the posted data have already gone through the wire as plain text?

I'm trying to upload a file to my MVC 2.0 app, but I keep getting connection resets. I know that the file size limit can cause these, but it's currently set at 20MB in the web.config and the file I'm trying to upload is only 3MB...
I'm not sure how to diagnose this issue and I can't look into error handling on the MVC side since the request never makes it there...

In an asp.net web form, I keep getting a connection reset error message. The page is doing a some long running processing (about 2-5 minutes).
I have no problem when the web request comes from the same machine as the web server. But when the request originates across the network, I get a connection reset error about 1:30 or 2 minutes into waiting for a response.
I have set the in web.config for this application and put the application it's own application pool.
What else can I try?
Edit
The purpose of this page is to accept input from the user, calculate something, and send the result back to them. The long running calculation isn't something I can offload until a later time.

On an ASP.NET Web Application I have an upload file functionality. I'm restricting the file size up to 10 MB by configuring the inside web.config the maxAllowedContentLength attribute. (I'm using IIs 7.0 BTW).
It get the desired HTTP Error when I access the application from the local machine:
HTTP Error 404.13 - Not Found The request filtering module is configured to deny a request that exceeds the request content length.
When I access the application from another machine I get
The connection was reset The connection to the server was reset while the page was loading.
How can I get a more descriptive error when my application is accessed remotely?

I hope this is a really easy question but I'm struggling with it. I have a GridView that has an UpdatePanel within a TemplateField.
The idea is that the user can make simple alterations without a full page load being required.
I have simulated my page functionality in the following example, which simulates a database hit, gridview databinding and updatepanel functionality.
When you press any of the + or - buttons in the GridView, the form controls in the bottom UpdatePanel also post their contents back. I have seen this by using Firebug. On my real page however this is causing excessive bandwidth and is nearly the same as a full postback.
how I can force ONLY the appropriate UpdatePanel's contents to postback for processing, rather than all the UpdatePanels?? I've tried experimenting with Triggers but just can't get it working properly.

I've read several questions explaining how to handle file uploads in asp.net mvc. I am trying to submit both the file as well as form fields describing it. That might be the issue. I'll go write to the code:
View code:
<% using (Html.BeginForm("CreateFile", "Video", FormMethod.Post, new { enctype = "multipart/form-data" }))
{%>
<fieldset>
<legend>Fields</legend>
<p>
<label for="file">Filename:</label>
<input type="file" name="file" id="file" />
</p>
<p>
<label for="Password">Password:</label>
<%= Html.TextBox("Password")%>
<%= Html.ValidationMessage("Password", "*")%>
</p>
<p>
<label for="Description">Description:</label>
<%= Html.TextBox("Description")%>
<%= Html.ValidationMessage("Description", "*")%>
</p>
<p>
<label for="DateUploaded">DateUploaded:</label>
<%= Html.TextBox("DateUploaded")%>
<%= Html.ValidationMessage("DateUploaded", "*")%>
</p>
<p>
<label for="DateRecorded">DateRecorded:</label>
<%= Html.TextBox("DateRecorded")%>
<%= Html.ValidationMessage("DateRecorded", "*")%>
</p>
<p>
<input type="submit" value="Submit" />
</p>
</fieldset>
<% } %>
Controller code:
[AcceptVerbs(HttpVerbs.Post)]
public ActionResult CreateFile(VideoDTO video, HttpPostedFileBase f) //[Bind(Exclude="VideoId")]
{
foreach (string file in Request.Files)
{
HttpPostedFileBase hpf = Request.Files[file] as HttpPostedFileBase;
if (hpf.ContentLength == 0)
continue;
string savedFileName = Server.MapPath("Videos") + Path.GetFileName(hpf.FileName);
hpf.SaveAs(savedFileName);
video.FileName = hpf.FileName;
}
repository.CreateVideo(video);
return RedirectToAction("Index");
}
I've seen several examples, but haven't come across one that is trying to submit both a file and other form data. Some other things of note is other examples seem to not put a HttpVerb attribute on the action method at all and have an empty parameter string. The files I'm looking to accept will be video files of various types but they can be anywhere from 100-300 mb. The files I've attempted to use (locally) have been rather small comparatively (50 or so mb).I know it's been asked but I feel like my issue here is different somehow. When I submit the page I see:
The connection was reset
The connection to the server was reset while the page was loading.

I am experiencing the following page error when trying to use the FileUpload control on my web page to upload files larger than 3MB or so. The error is as follows:"Problem loading page The connection was reset The connection to the server was reset while the page was loading.
* The site could be temporarily unavailable or too busy. Try again in a few moments.
* If you are unable to load any pages, check your computer's network connection.
* If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the Web."I suspect this may be due to a timout issue. If so, how can I increase the timeout period for this control / process? I am coding in VB.NET.

In my ASP.NET MVC2 web app I have a page which goes off and gets results from a number of different web service feeds. These return times vary so I want to basically display them as they return after the page loads. I also want my user to be able to kick of requests that can run concurrently with these other requests.
At the minute my page just seems to queue up the requests. The web service calls returning one at a time in the order they are called and then the user can kick of requests.
Is this a case for the asyncController or is there an easier/better way of working this?

I have a couple of fields on a form that will be populated with default values. I would like to put a button that will allow me to reset those fields to their default values if they have been modified. However I would like to avoid the postback so that I don't have data being sent to the database. Is it possible to add a javascript hook such that when that button is pressed I can pull the default values and populate those fields in javascript?

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.

the idea id I need to send data to the client to the server to inform the server of some events at the client, and i need to send data from server to the client to inform the client of some results on the server. now from client to server is easy I use xhr easy enough. and to send data from server to client I thought of using long polling in xhr so to test I wrote the following code:
[code]
<!-- Test.aspx -->
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Test.aspx.cs" Inherits="Test" %>

asp.net using visual studio 2008 3.5 framework with sqlserver 2008. I have a webform (derived from master page) so its a content form with content placeholder. It has two text boxes, dynamically populated checkboxes from database and 8 radio button groups. It has two custom validators attached with two of my fields also. I've tried every way to clear my form but its not working somehow. I've tried Control iteration method. Ive tried btnReset.Attributes.Add("onClick","document.forms[0].reset();return false;"); thingy...but none is working.

i am using this code to reset all my textboxes and Dropdowmlists after the button is clicked:
void resetField(object myObj)
{
//RadioButton rl;
string temp = myObj.GetType().ToString();
switch (myObj.GetType().ToString())
{
case "System.Web.UI.WebControls.TextBox":
((TextBox)myObj).Text = "";
break;
case "System.Web.UI.WebControls.DropDownList":
((DropDownList)myObj).SelectedValue = "N/A";
break;
default:
break;
}
}
i have tested this code and it works great separately .. the only difference is on my project i have DIV, tables, TABs and ContentPlaceHolder. not sure if this can make this code not working.. i am not getting any error..but nothing is happening.
