Queue Reordering

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.
Drag-to-Reorder Queue

Reorder queued files before uploading begins. Use the up/down buttons to change the upload order. Files are uploaded sequentially in the displayed order.

What you should see: drag rows to reorder before starting - auto-upload is off and concurrency is 1, so the order you set is exactly the order used.
var uploader = AjaxUploader.create('#uploader', {
 uploadUrl: '/ajaxupload.axd/upload',
 multiple: true,
 autoUpload: false, // manual start after reordering
 concurrency: 1,
 onSelect: function(files) {
 renderQueue();
 }
});

// Reorder with uploader.moveTask(taskId, newIndex)
// Then start: uploader.startUpload();
