How Can I Restrict The File Type In The File Browse Menu Of An AsyncFileUpload AJAX Control Toolkit

Jul 28, 2010

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.

AJAX :: Asyncfileupload Won't Upload Same File Twice

Nov 29, 2010

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?

Ajaxcontroltoolkit - Ajax Toolkit AsyncFileUpload - "The File Is Attached Is Invalid" Error

Feb 22, 2010

I'm trying to use the AsyncFileUpload control from the Asp.net Ajax Control Toolkit (Sept 30, 2009 stable build: 30930) . I've created a demo application and the control works fine. Files upload and all is well. When I try to use the control in my real application, I'm always receiving an error stating "The file attached is invalid". The AsyncFileUpload control returns this when the file uploaded is null.

To isolate the problem, I created a new master page exactly like the master page in my demo app. I also created an aspx page exactly like the page in my demo app. The upload still fails with a "The file attached is invalid" error. I also compared the web.config for the real app and the demo app and couldn't identify any differences that should matter. The code below is the test code in my real app. This code is exactly the same as the functioning code in the demo app with the exception of having different class names and file names. The web.config listed below is from the real app with the appsettings and connectionstrings removed. Real App Test Master Page:

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.
