AJAX :: Asyncfileupload Doesn't Work As Put It In A Control?
Jun 7, 2010
I can't get my <ajax:asyncfileupload> working and I don't see why...
When outside any panel or table it is working well, but as soon as I put it in a <asp:panel> or table I get a strange error which seems to be on client-side but I don't understand what's happen here. Here is the code and code-behind and Javascript.
Here's the error:
[URL]
Here's my front-code:
[Code]....
Protected Sub fupAjoutLogo_UploadedComplete(ByVal sender As Object, ByVal e As AjaxControlToolkit.AsyncFileUploadEventArgs)
I'm having a problem with a Webusercontrol that has an asyncfileupload control. My websusercontrol is being loaded in a placeholder control that's wrapped by an updatepanel.Due to asyncpostback, I have to load and clear the placeholder's controls.
The webusercontrol works flawlessly, except the asyncfileupload, which doesn't want to upload at all. I can assure that the code is without error, because I used to have the webusercontrol running as an *.aspx site.
I guess that the problem is the fact that the control has to be cleared and reloaded with every asyncpostback ?
I have an asyncfileupload control within a panel control. The panel is initially set to visible=false on page load. After a user clicks a button to display the panel contents however, I set the panel to visible and the user can then use the asyncfileupload. The problem however, is it seems much of the javascript associated with the asyncfileupload, does not function properly when the panel containing the upload control is set from invisible to visible. If I set my panel's "visible" property to "true" initially, then it works fine. My javascript error message is as follows:
"Form contains a file input, but is missing method=POST and enctype=multipart/form-data on the form. The file will not be sent."
Basically within my asyncfileupload control, I have the following line:
[Code]....
In this scenario, my "args" variable is always null (when I set my pane's "visible" property to "true" on page load, the args variable DOES contain data. Any idea why switching a panel from visible=false to visible=true, would cause an error like this?

I am having quite a bit of trouble getting an accordion control to work. I downloaded the AJAX Control Toolkit (v 3.5), added the dll to my toolbox, and added an accordion control with the following code:
i am using mod_aspdotnet.so module to hosting my ASP.NET application. all was ok until i use ajax control tool kit in my aplication. I am using ajaxToolkit:CascadingDropDown to conect 2 dropdownlist in cascade. In IIS every thing works fine, but in apache there are some problems. When load the page, i got the next javascript error: 'Sys' undefined. the object signed are :
i am using VS2008, 3.5 .net and have installed ajax control toolkit and added controls into toolbox, that was fine. But, i can't get any of control to work, nor it renders in design view on my page. Control source is created, page builds without errors but controls don't work. For example:
I created a .NET user control to work as a DropdownCheckbox and added Jquery to give the sliding and hide effects. The code is as below:
[Code]....
This control works fine in a normal page, but once I put it inside an update panel it doesn't work. Is there a work around or simply I can't use JQuery inside update panel?
If i use signs like ë in the HTML Editor, in IE, its ok, and works. But if i use ë in firefox in the same page with the HTML Editor. If i press safe the ë is converted to: � (copy past doesnt work well, but its a square if you put [] to each other). But how is this possible? And how can i solve this problem? In IE its working well, but 50% of the users of the system i build are using Firefox. So it should work in all editors.
As far as I can see, the following code should make an AsyncFileUpload display in ModalPopupExtender. The MPE shows fine but the AsyncFileUpload doesn't load inside it. I also tried removing the update panel and putting the divs both inside and outside of the update panel, all with the same (lack of) results. And the AsyncFileUpload displays and works outside of the MPE.
I am using the AsyncFileUpload control in AJAX. This code that I use works fine. What it does it to replace an existing .JPG file that was choosen from the users computer.The thing that I wonder now is that when the .JPG picture was replaced I am using this code to show the uploaded picture in an ImageControl
i'm trying to develop a ASP.Net control. If it based on System.Web.UI.Control id doesn't work correctly with Ajax.Net updatePanel. If I change it to System.Web.UI.WebControls.WebControl the it works fine with Ajax controls. What is the difference between them and how I implement it on Control based Control?
I recently came across the AsyncFileUpload control in the latest (3.0.40412) release of the ASP.Net Ajax Control Toolkit. There appears to be an issue when using it in a hidden control that is later revealed, such as a <div> tag with visible=false.
I am a new to WCF. I have written ajax to use a web service before, but on this project I am trying to use ajax to WCF.After I build the project and wcf using ajax, I receive the return successfully. But, 10 or more minutes later I don't get a return, the ajax calls the error function, and the fiddler returns nothing.
If I rebuild the project without any source modifying, I receive the return successfully again.
I have a webdayview control (Infragistics proprietary ASP.net control) on my page. On the aspx source I've inserted some javascript (webdayview_click - clientside click event) that calls a webmethod in the codebehind. This seems to work fine, but when I insert this webdayview control into a user control and move the corresponding javascript into the aspx of the user control, it doesn't work. I can't even insert a breakpoint into the javascript function to debug it. Is there a way to make it work? I want to enable the click event of the webdayview control so that when I click on it, the javascript function calls the webmethod. Here's my code (remember it is inside a user control):
[code]...
I posted this question on the Infragistics forum but didn't get any replies. Hopefully I'll get some here. :)
