AJAX :: Asyncfileupload Doesn't Work In Webusercontrol?
Aug 28, 2010
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 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:

Here's my front-code:

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?
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 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'm getting the following error on deployment of a tested application where ajax runs fine on the developmental system On deployment, I'm running asp 4. I downloaded ajax4 and extracted it into the /program files/ajax folder. Do I need to register any .dlls or anything? I don't see that in the Ajax installation instructions.

I created a web application which uses AJAX. When I debug the application on my local C drive it works fine. When I move it over to my shared server F drive and debug it, I get permission errors for every time I used AJAX in the web application. The errors look like this:
Request for the permission of type 'System.Web.AspNetHostingPermission, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed. F:JoshAJAXCCRSchedulingTESTShiftScheduleVsWorked.aspx
I have done almost everything including set my security level to full trust (which is what most people say is all i have to do). I do not know what else to try. Any other ideas? Could it be because I am on the .net framework 1.1 configuration? Do I need to add something to it?
When I downloaded the Ajax Tool Kit 3.5 and extracted the files, I then opened a site and went to the design view of a aspx page and clicked in the tool box, added a new catagory called tookit and then right clicked and selected "Choose Items". Everytime I've done this it closes out MS Studio 2008 Pro? Can someone tell me what to do? I need that ajax tool kit for future projects on the web, and for one that I'm just starting on now
I just download and install the Ajax Control tollkit, run my VS 2008 and add the dll to tollbox. Then I put textbox add calendar extension, run project click on text box i FireFox and the callendar doesn't show why ???
I am using an UpdatePanelAnimationExtender but the onUpdated event does not fire. The idea is that while updating I will show a gif and when the update is done the gif will become invisible...
