AjaxFileUpload - Files over 20mb

The AJAX Control Toolkit \ 17.1.1

The installation method

• Installer
• [X ] NuGet package
• A custom build from the source code

Minimal steps to reproduce the bug

<ajaxToolkit:AjaxFileUpload ID=“AjaxFileUpload” runat=“server” onuploadcomplete=“AjaxFileUpload_UploadComplete” ThrobberID =“myThrobber” MaximumNumberOfFiles=“1” AllowedFileTypes=“wma,mp3,m4a,wav” ClearFileListAfterUpload=“true” OnClientUploadStart=“UploadStart” OnClientUploadComplete=“UploadComplete” />

Actual result

In 17.1.1…

<script type="text/javascript">
//<![CDATA[
Sys.Application.add_init(function() {
    $create(Sys.Extended.UI.AjaxFileUpload.Control, {"allowedFileTypes":"wma,mp3,m4a,wav","clearFileListAfterUpload":true,"clientStateField":$get("cphPageContent_ModalStudentAudio_AjaxFileUpload_ClientState"),"contextKey":"{DA8BEDC8-B952-4d5d-8CC2-59FE922E2923}","enabled":true,"maximumNumberOfFiles":1,"postBackUrl":"/test/student_audio?id=9290","serverPollingSupport":true,"uploadHandlerPath":"/AjaxFileUploadHandler.axd"}, {"uploadComplete":UploadComplete,"uploadError":UploadError,"uploadStart":UploadStart}, null, $get("cphPageContent_ModalStudentAudio_AjaxFileUpload"));
});
//]]>
</script>

• This works with files < 20mb, and fails when over. *

Expected result

In 16.1.1…

<script type="text/javascript">
//<![CDATA[
Sys.Application.add_init(function() {
    $create(Sys.Extended.UI.AjaxFileUpload.Control, {"allowedFileTypes":"wma,mp3,m4a,wav","clearFileListAfterUpload":true,"clientStateField":$get("cphPageContent_ModalStudentAudio_AjaxFileUpload_ClientState"),"contextKey":"{DA8BEDC8-B952-4d5d-8CC2-59FE922E2923}","maximumNumberOfFiles":1,"postBackUrl":"/test/student_audio?id=9287","serverPollingSupport":true}, {"uploadComplete":UploadComplete,"uploadStart":UploadStart}, null, $get("cphPageContent_ModalStudentAudio_AjaxFileUpload"));
});
//]]>
</script>

Yes, that’s working - thanks.

I’ll double-check this resolves my issue on the other computer on Monday.

Thanks
