am using the AsyncFileUpload, when the AsyncFileUploadEventArgs event is fired i need to check if a textbox as been populated which i am doing. the problem is i am setting the validator to invalid. i would of thought this would display the error to the user, but nothing happens

{

I tried this tutorial [URL] .... It doesn't work with and vs 2010, and ajax control toolkit 4 ( I downloaded from link belowand vs 2010) and It doesn't work with ajaxcontroltollkit 3.5 I downloaded from same link.but when i put Your AjaxControlToolkit.dll in bin folder of my project it works fine.
I downloaded the same version of tolkit.dll as yours (3.0.30930.0) and I worked for me.

View 1 RepliesI moved from the FileUpload control to the AsyncFileUpload control.
1) Do AsyncFileUpload controls work under UpdatePanels??? (Please provide example or reference)
2) Can AsyncFileUpload controls be triggerd with an update button (both inside the same updatepanel)?
I can't get the OnClientUploadStart function to trigger when the upload starts. I also can't get the throbberID to work.

I am just about to learn how the AsyncFileUpload component works. I have come up with some code but this does not compile excactly. It seems but are not sure that I need to declare some events etc... I will explain excactly what my goal is to do. It will be possible to upload a .jpg file from a users computer and save this file to the below path with a new name:
UploadedFile.jpg
"~/Folder1/Images/"
[Code]....
Is there any solution short of posting back, which completely defeats the entire purpose of this control?
View 1 RepliesI have built a custom Ajax User Control which uses the AsyncFileUpload control released with the latest Ajax Toolkit.
On my local machine the application works fine without error, however if I deploy the app onto my web server the functionality breaks.
I am trying to add a file via the AsyncFileUpload control, save it to the web server, then save some details into a datatable which is displayed in a gridview. All of this sits in an update panel.
When uploading small files (under 55kbs) the process works fine, however when uploading larger files, it doesn't like it. The control uploads the file successfully to it (the client error is not triggered), but it breaks when I try to save it to the web server. Upon saving, the document saves OK, but all the data is stripped away. It just saves the filename with no content. It looks like the AsyncFileUpload control has lost the File in session, therefore cannot save it. However the AsysncFileUpload.filename still exists and AsyncFileUpload.HasFile is returning true.
Has anyone seen anything like this before or have any ideas why this could be happening? I have set the web config httpRuntime maxRequestLength = 20480, so it shouldnt be that.
See code:

I'm developing a website using .NET 3.5 and I'm having problems with the asyncfileupload control.The problem occurs when you upload a file, and then try upload the same file again. On the second upload, none of the clientside nor serverside methods fire. Everything works fine if you upload one file, upload a file with a different name and then upload the first one again.
This is a bit if a pain because on the page i allow the user to delete the uploaded images so i need the functionality to upload a file with the same name as the previous upload.Has anyone else encountered this and are there any work arounds?
I'm using ajax.toolkit asyncFileUpload to do the async image upload.
I don't know how to get the new file name that i give it in server side.
This js function
[Code]....
only returns the name of the filename on the client, not the new name that I have given server side
how can I do?
I have my asyncfileupload set up to give the posted file a new guid as its filename, what i need is the NEW filename so i can insert it into a database. PostedFile just gives me the original name, as does args.get_fileName().
Here is my codebehind:

I'm new to ASP.NET AJAX AsyncFileUpload so I've created an aspx page to test it but it seems there's some bug with that control because the server side UploadedComplete event does not fire.
the aspx :

<div>
<asp:ScriptManager ID="ScriptManager1" runat="server">
</asp:ScriptManager> [code]....
I have been using the asyncfileupload control and have everything working nicely with it when uploading. However, also on my page the user can download a file.
If the following path is taken the asyncfileupload does not behave correctly:
1: Download a file
2: Attempt to upload a file via the asyncfileupload
When the user attempts the upload, the previous event is fired, which causes the download to fire again and the asyncfileupload freezes.I'm not sure why this is happening but I think it's to do with the response.end of the download and the
asyncfileupload/toolkitscriptmanager.

I an begginer programmer and this is first time i see that kind of error. When AsyncFileUpload is outside the Panel or AsyncFileUpload everthing works perfect but i need this in AsyncFileUpload.

I have an updatepanel to which I am adding a web user control dynamically. This web user control has an AsyncFileUpload. I have read several articles that tell that asyncfileupload control will not work if added at run-time. As suggested by some of the articles,I tried adding a static asyncfileupload control but still it does not work.I need to have 5 file upload controls in the web user control. Do you think I can make them to work or should I completely do a re-design or go with full postbacks. My preference is to be able to use asyncfileupload control and I am willing to invest time in making them to work since they improve the user experience by many folds.
View 3 RepliesIf I use the AsyncFileUpload control and I test the page local with VS2010, I get for files above 3.8 Mb an No Access Error.If I go to the AJAX control test page and try to upload a file larger then 3.8, there is no problem.I just installed VS2010
