AJAX :: Asyncfileupload Control - Select A File It Saves Another File?
Jan 23, 2010
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 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 new to this ASP.NET and AJAX.I am trying to learn AJAX. I Have one doubt.what is the difference between normal file upload control and ajax AsyncFileUpload Control ..?
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. [Code]....
My problem is Asyncfileupload control is working fine when i debug the application and upload large file...but when i run this from iis it only upload file less then 5 kb. why is that so?? i did try adding Httpruntime maxRequestLength="4096" i tried to find on search but no help... did m i mising any settings..??
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.
When selecting an image for an item in file upload control of ajax toolkit (AsyncFileUpload), the only files that should be displayed are ".jpg, .jpeg, .gif, .bmp, or .png".
this is my compelete code for validation type and display image with AsyncFileUplaodI'd like to upload only png, jpg, gifI can upload Image and have its preview successfullyand when try to upload another type It prevents and fortunately I can see this message"Upload a valid file with extension png, jpg, gif."but UnfortunatelyIt shows a message box with this errotUnhandled Exception: this._innerTB is null what's my mistake?

Our problem/question revolves around an upload control that loses the selected file (goes blank) when a postback control is used (in this case, the dropdown list posts). Any insight into what we are doing wrong or how we can fix this? Below is our code and a summary of the problem.
I am wondering if it is possible (for as little money as possible) to create a web page that when a user clicks the submit button saves a file as a PDF. it is going to be used as a purchase order creator on a webpage. I have seen a few tutorials around but they seem to use software that requires purchasing a license.
I have an asp.net panel having various controls including gridview. I have converted this panel into pdf and attached it as an email attachment using memory stream. Everything is working fine. Now I have an File upload control outside panel through which I have to attach a file and send it in mail along with the already attached panel. But I am unable to figure out how to do it.
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:

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

My folder hierarchy is Users/Resources/Avatars/UsernameThere is also an error appears for this line of code- Error: CS0176:Member'System.Web.UI.ScriptManager.RegisterClientScriptBlock(System.Web.UI.Control, System.Type, string, string, bool)' cannot be accessed with an instance reference; qualify it with a type name instead
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:
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 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
I'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?
