We tried your code with the latest version and it works fine. Try checking whether you have the latest version first, then following guidelines in this post:

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="testAjaxUploader.aspx.cs" Inherits="iBelong.ContentStore.UI.Web.Pages.testAjaxUploader" %>

<%@ Register assembly="EO.Web" namespace="EO.Web" tagprefix="eo" %>

<body>
<form id="form1" runat="server">
<div>
<eo:AJAXUploader ID="AJAXUploader1" runat="server" Width="250px" TempFileLocation="~/UploadTemp"
OnFileUploaded="ajaxUploaderForTest_FileUploaded" AutoPostBack="true">
<LayoutTemplate>
<table border="0" cellPadding="2" cellSpacing="0" width="250px">
<tr>
<td>

Hi,

We have tried your code multiple times and it worked fine here. The only differences between our code and your code are:

1. We have an empty code behind .cs file. The test page class inherits directly from System.Web.UI.Page. So check whether your code behind class iBelong.ContentStore.UI.Web.Pages.testAjaxUploader contains additional code;
2. We changed the uploader's TempFileLocation. Which should not cause any problem;

We then set a breakpoint in ajaxUploaderForTest_FileUploaded handler and it always get hit when the file finishes uploading.

So it appears the problem is related to your project (or at least some how triggered by elements in your project). I would recommend you load our sample project and verify if that works; If that doesn't work we can setup a web meeting to take a look on your machine to see what we can find.

Thanks

We solved this problem. AJAXUploader does not accept posting when trace is enabled. We disabled trace and it works now, it does not make sense that trace has to be disabled for it to work.

What's going on?

This is a known restriction. ASP.NET's trace module tries to fetch all the form data (which is the whole file) before it hands over the request to down stream, and it usually fails while fetching the data when it's too big. Our uploader never got a chance to handle the request in this case.

You should have answered that from the beginning. It would have saved us a lot of time! Or at the very least you should include that in your documentation.

It would be pretty hard for us to make any connection to this when the question is titled as "AJAXUploader within a pageView of a Multipage". :)

Totally agree. We will try to put this into our documentation as soon as possible.
