I would like to have possibility to provide service extending angular's http service to perform API calls. 

We want to upload file on click of any kendo button or Kendo icon button.

We don't want the drag and drop feature in that. On click of a button, it will ask us to select a file and on click of OK, that file will be auto-update or thumbnail of that file shown besides to that button.

There are cases where the drag & drop area is not used.

The purpose of the 'compact' option is to remove the drag & drop area and leave just the 'Select files' button, like defining:

<input type="file" />

Change the tabindex of input tag from - 1 to 0. So that enter key press will work with screen reader tools.

Alt+Enter is working but screen reader reading like "To activate press Enter".

To reproduce :
