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.

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.

Data Controls :: File Type And Extension Validation For Multiple File Upload Controls Using Custom Validator

May 7, 2015

I was referring muddasar's one of the article for the validation. Below is my code and i am trying to validate the file upload selected file format on the submit button. I have 4 upload control and  fu1 is mandatory field and others are not mandatory fields. Though i need to validate all the four uploads if the files have been selected. My full sample code is below for easy testing,

<asp:FileUpload runat="server" ID="fu1" />
<asp:Label ID="lblMessage1" runat="server"></asp:Label>
<asp:FileUpload runat="server" ID="fu2" />
<asp:Label ID="lblMessage2" runat="server"></asp:Label>

[code]...

I am doing slight mistake on the return to the main function. if i test indvidual function it works fine. whereas if i include the 4 functions in one function  with the return statement, it's not validating. goes to to the server.

Web Forms :: File Extension Validation In FileUpload Control?

Jun 23, 2010

Actually i am using JavaScript validation for Image or Word or Excel File & its working perfectly. My aim is making its full professional.

For Example When you use Photoshop and open any file you see only those extension which are applicable for Photoshop i.e. jpg, jpeg bmp, psd, png etc. You never see .doc, .xls or any other which are not open with Photoshop. This is i want to do, When i open for an Image it should show only Image Type file extension in file type By default its its showing All Files, As i use extension validation in JavaScript, it never accept .doc or .xls files in Image Type Validation but it will show. I want only that file type show for which i open.

AJAX :: AsyncFileUpload Assigning Styles To Input Type=file Element?

Jul 13, 2010

AsyncFileUpload control is rendering in this way.

<span
id="Span1"><input
type="hidden"
name="uploadinput$ctl00"
id="uploadinput_ctl00"
/><div
id="uploadinput_ctl01"
name="uploadinput_ctl01"><input
name="uploadinput$ctl02"
type="file"
id="uploadinput_ctl02"
id="uploadinput_ctl02" onkeydown="return false;"
onkeypress="return false;"
onmousedown="return false;"
style="width:
355px;"
/></div></span>

Is there any way to assign styles(like width, position,top etc..) to Input type=file element alone.One way i can see, is using Jquery document.ready eventhandler,

$(function(){
var element = document.getElementById('<%=uploadinput.ClientID%>').lastChild.firstChild;
element.style.width = '150px';

but the problem with that is, i am not able to identify input type = file element after postback in that document.ready eventhandler.please let me know if there is any other way to assign styles to input file element of AsyncFileUpload control with out any issues.

AJAX :: Asyncfileupload Control Not Working On Server?

Feb 19, 2010

i use a asyncfileupload control to upload files from my web pages. since i have a listview inside an update panel, and the listview needs to have the file upload functionality, i can not use a asp fileupload control.

the uploaded files are saved inside a temp folder in my application directory. i use a asp:button to upload files from the asyncfieupload control to my temp folder.

as long as i work on my local machine, the upload control inside the listview works perfectly fine, and does what is expected of it (i.e upload files :))

but when i move the code to my web server the asyncfileupload onthe page works just once, that is, it uploads just once (no matter whichever row of the listview it is) and for all other subsequent uploads, it uplaods a file of the same name to my temp folder but with 0KB size.

it beats me why asyncfileupload control would behave this way in the two environments.

could anyone suggest a possible reason/or something i m missing to configure on the server?

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.

AJAX :: Updating The Page After File Upload Using AsyncFileUpload Control?

Jan 24, 2011

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.

Make IE Detect File Type Without Extension?

I'm trying to let the user download different documents where the data is stored in an SQL DB. In firefox, the filetype is correctly read, but not in IE. I'm trying to do this without having to set the ".pdf" or whatever extension the document has, because I haven't got that information. I only have the filetype.

AJAX :: AsyncFileUpload Working Locally, But Not On IIS 6

Feb 3, 2010

I 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:

AJAX :: AsyncFileUpload Inside FormView Not Working?

Jul 25, 2010

I have a FormView inside a user control, and in the InsertItemTemplate, I have an AsyncFileUpload control, that I would like to to use. On the user side, it seems to work, but it doesn't work on the server side code behind. The HasFile Property is always false, and it doesn't fire the UploadCompleted event either. My UpdatePanel is in the master page.

<asp:FormView

UploaderStyle="Traditional"

ErrorBackColor="Red"
onuploadedcomplete="AsyncFileUpload_UploadedComplete"

AJAX :: AsyncFileUpload Not Working When .net App Published To Server?

Mar 9, 2010

AsyncFileUpload not working when .net app published to web server. It works fine in testing on my pc. I have checked security settings. I can get other upload scripts to work, but I wanted to try using the AJAX AsyncFileUpload. I thought maybe it's something on the server blocking it, but not errors, It just keeps saying "uploading" but it never finishes and it never uploads the file. Has anyone else had this happen?
