View 3 RepliesI have got an error "server response error : Unknown server error" while uploading file using Ajax AsyncFileUpload, code behind function is triggered while uploading, but after code behind function executed, we are getting this error.
View 1 RepliesI would like to restrict what they see in the file upload dialog, which is set to "All Files" by default. I understand how to validate that they only uploaded a certain file type, that is not the question here. I would just like to know how to default the file type in the file selection dialog.
Is there any way to change this to "PNG only" or "*.png"?This is using AsyncFileUpload in the ASP.NET AJAX Control Toolkit.
I am using this control to give the user the possibility to upload up to 5 pics. Well, it generally works fine but i started to test it using a folder full of pics. This folder contains more than 900 pics which are named from "DSC_8138.jpg" to "DSC_9255.jpg" (some has been deleted).
When i try to upload the pic "DSC_8138.jpg" it saves the pic "DSC_8168.jpg".
When i try to upload the pic "DSC_8141.jpg" it saves the pic "DSC_8147.jpg".
There is not any clear critieria in this.
I am quite sure that my code in the AsyncFileUpload1_UploadedComplete method cannot cause this problem. Actually, when i try to upload the pic "DSC_8141.jpg" the file name is still "DSC_8141.jpg" even though the pic uploaded is the "DSC_8147.jpg". in any case, the control deals with the uploading process.

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?

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 have added AsyncFileUpload to creata user wizard control. When I tried to upload the file this control seemed to work fine an show confirmation at the end. But when I checked the website no file has been uploaded at all.know why its not uploading the files/images

I have downloaded a AsyncFileUpload example, I edited the uploadError javascript and now it is working perfectly:
[Code]....
It works perfectly how I wanted it, like this: I upload a file, if it's an Image I get the Lime AsyncFileUpload background, and the file name and size are written under the AsyncFileUpload, if it's not an Image, I get the error label shown, with red AsyncFileUpload background, and if I upload another file, it keeps working the same thing every single time, but only shows the last uploaded image name at the end of an image upload, not all of the images.I tried to merge it with my website, and ended with this code:
[Code]....
but in my website its just working the first time only, then rest times I'm getting the uploadError() function working instantly when I click upload, even if i have selected an image or anything else.
I'm saving a file with the asyncfileupload ajax plugin from the ajax toolkit and when I save it I'm changing the filename (to avoid multiple files with the same name).
After the file is uploaded, the user needs to know what the file has been named so I'm using this javascript code on the onclientuploadcomplete event.
function UploadComplete(sender, args) {
alert(args.get_fileName());
}
This works except it gets the old name, not the new name (which is determined server-side). Is there any way to get it to return the new name rather than the old name? Or any work around to achieve this?
This is my code in the code behind the get the new filename:
string filename = DateTime.Now.ToString("dMyHmsf") + e.filename;
string strPath = MapPath("~/SavedImages/") + filename;
AsyncFileUpload1.SaveAs(strPath);
I am using an AsyncFileUpload control inside a FormView. I only want the file to saved during the FormView's ItemInserting event. In trying to find a way to do this, the only thing I could come up with was to store the AsyncFileUpload control or the PostedFile in a Session variable during the OnUploadedComplete() event and then invoke the SaveAs method in the ItemInserting event. Problem is the SaveAs method is throwing an exception saying "Cannot Access A Closed File". If I invoke SaveAs in the OnUploadedComplete() event, it saves successfully, but I need it to only save when the user submits the form. this error or perhaps a better way to save the file during ItemInserting()?

I want to make it so that if the file exists it changes the name of it, is there any built in functionality for this? Classic ASP had a parameter so that when you upload say house.jpg, and then again it would become house(1).jpg etc etc which was useful.
I want to upload a file INSIDE an updatepanel using the asyncfileupload control.
But in the code below the filename is EMPTY! Why?
Protected Sub dvTicketDetail_ItemUpdating(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.DetailsViewUpdateEventArgs) Handles dvTicketDetail.ItemUpdating
Dim afupload As AjaxControlToolkit.AsyncFileUpload = CType(dvTicketDetail.FindControl("afuFlyerEdit"), AjaxControlToolkit.AsyncFileUpload)
'only upload physical file if fileupload control is NOT empty
If afupload.FileName <> "" Then
'a new file must be assigned to record
End If
End Sub

View 4 RepliesI'm using the ajax asyncfileupload plugin to upload files to my server and it works fine for the first file upload but if I try to upload another file before refreshing it throws the exception "Unhandled Exception: $common is undefined".
If I add 'location.reload()' to my UploadComplete javascript method it fixes it but obviously this isn't ideal. Does anyone know how to fix this?

I am facing a problem with Ajax file Upload control
how to Upload image using ajax file upload control on Button click event in asp.net
i don't want to use the upload button what has placed on ajax file upload control .
I Just place the extra button on that button click event only i want to insert the image into my databse.
We recently migrated applications from one web server to another. Previously they could upload files to the server and if it already existed, it would over write with the new one.
Now I have to manually delete the file from the server so they can upload a new one. If I delete it they can upload a new one and even upload one to overwrite the one they uploaded. But only after I delete the "migrated" one.
All of the security is correct. ASPNET and IIS_WPG have permissions.
Da Code:
If System.IO.File.Exists(UploadLoc + Me.FileUpload_PDF.FileName) Then
System.IO.File.Delete(UploadLoc + Me.FileUpload_PDF.FileName)
End If
Me.FileUpload_PDF.SaveAs(UploadLoc + Me.FileUpload_PDF.FileName)
I get the dreaded "access to the file is denied"
Update: I find if I give "USER" modify rights it works, but that does not seem secure.
am trying to use the AsyncFileUpload control in ajax toolkit to upload a picture file, save the file on a location on the server's filesystem and display the picture file back to the client system. I have both the image and AsyncFileUpload controls inside an updatepanel but its seems the UploadedComplete server code is not firing when the file upload completes any clue?

I am having a strange issue associated with AsyncFileUpload control. after the upload, I am updating the page by calling__doPostBack function from ClientUploadComplete event handler. it works fine first time, but next time I try to upload the file, it refreshes the page first before uploading, then does the upload and refreshes the page again. not sure why refresh page is being called twice once before the upload and once after the upload. I have a simplified version of this code which has this bug.
