Upload Collection & File Uploader drag & drop issue in IE

[Former Member]

Dear experts,

I've figured out that we could use drag & drop feature to upload via Upload Collection by drag the files and drop them at the Plus button or via File Uploader by drag and drop files in the field.

However, this feature is workable in Chrome & Firefox. I've tried it on IE11 & 10. It doesn't work; it will ask you to open or save the files directly.

As I find on google, I need to handle these events. One problem is how I integrate with the SAPUI5 Fileuploader library since when I use this, it will disable the function drag&drop on Chrom & Firefox as well:

window.addEventListener("dragover",function(e){
  e = e ||event;
  e.preventDefault();},false);
window.addEventListener("drop",function(e){
  e = e ||event;
  e.preventDefault();},false)

I'm looking for anyway to enhance or extend this feature.

Thank you.
