I would like to call the click event of the the AsyncFileUpload control programmatically, is it possible? I tried to call the click event, but it is not working. actually I don't like the appearance of the upload, so I am trying to hide the AsyncFileUpload control, assign the file name and click it programmatically.

The AsyncFileUpload control turns green, indicating that the attachment was successfully uploaded, but the designated method for handling the server side UploadedComplete event is never executed.
View 6 Repliesin a form i have a buttoin, when click both OnclientClick and postback should happen. on clicking the "Email" button a client side "mailto" tag should do the work and pull a new message window on the client's machine.
whereas, the email addresses should be invoked by the post back. so , when clicking the button the server side post should happen and on return the client side script should be invokded with the values read during post back, and populate all the email addresses.
i need know how to first do a server hit take the values and then execute the client script with those values without using AJAX

I am using an update panel in my application. Inside the update panel i am trying to trigger a html button, which in turn should invoke a server side function after which i need to invoke a client side function.But the client side function is getting invoked first where as the server side function is not getting invoked at all.
Here is my code
<asp:UpdatePanel ID="embedcodepanel" runat="server" UpdateMode="Conditional">
<Triggers>
<asp:AsyncPostBackTrigger ControlID="btnembedurl" EventName="onclick"/>
</Triggers>
<ContentTemplate>

Apropos MSDN link: [URL] [.NET Framework 4 - ASP.NET] Implementing Client Callbacks Programmatically Without Postbacks in ASP.NET Web Pages Using the code from the above link in the following code snippet, if you keep a break point on the statement "if (IsPostBack)" in the Page_Load event. The control moves into the "if (IsPostBack)" block after the alert, which mean that it is a Postback. Then, how come you say "...Without Postbacks"? I am getting confused here.

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)?
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 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?
