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.

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.

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.

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:

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.

I'm using the new version of ajax control toolit - 40412. Installed it due to the previous version having problems with modal popup extenders inside update panels. I Installed the new version and found it worked fine as soon as I change my scripmanager to ToolkitScriptManager, However, I recentlly realised that now my sites hovermenus do not work in IIS6 (maybe 7 too) Ive tried in firefox and IE and the same. I changed from <asp:ToolkitScriptManager> to the old <asp:ScriptManager> and they work but I need the toolkitScriptManager cause of some new controls I have used will use need it. This is all implmented in my masterPage for the site so I will post the code (there is nothing in the code behind)
[Code]....
It all runs fine when I run as project from Visual Studio.
