AjaxFileUpload: Drag and Drop is not working on IE10 for Windows 7


It seems that Drag and Drop function of the AjaxFileUpload control is not working on IE10 (tested in IE10 for Windows 7).

For example the official sample (just try it yourself : http://www.asp.net/ajaxLibrary/AjaxControlToolkitSampleSite/AjaxFileUpload/AjaxFileUpload.aspx) is working well in Chrome and Firefox, but not in IE10.

A possible fix:
IE10 needs to bind preventDefault() to the dragenter event.

By adding:
$('div[id$="Html5DropZone"').bind("dragenter", function (e) { e.preventDefault(); });
I'm able to get the drop functionality working.

I'll be adding (in my local modified toolkit) to AjaxFileUpload.pre.js:
_html5OnDragEnter: function (event) {
