Chat File Sharing

Demo uploads land in a temporary store and are swept after 60 minutes. To keep files, handle FileUploaded — see Single File for the complete save pattern.
Chat File Sharing

Share files in a chat-style interface. Uploaded files appear as message bubbles in the conversation timeline alongside text messages.

What you should see: an attach control sized for a message composer - one file, uploads immediately, appears in the thread.
Hi! Send me the files.
AjaxUploader.create(el, {
 uploadUrl: '/ajaxupload.axd/upload',
 autoUpload: true,
 onComplete: function (file) {
 addChatBubble('File: ' + file.name);
 }
});
