File Draggable directive

Provides drag-and-drop features for an element such as a div.

Basic Usage

<div [adf-file-draggable]="true" id="DragAndDropBorder" class="drag-and-drop-border"
     (filesDropped)="onFilesDropped($event)"
     (folderEntityDropped)="onFolderEntityDropped($event)"
     dropzone="" webkitdropzone="*" #dragAndDropArea>
  <ng-content></ng-content>
  Drag and Drop files here!
</div>

Some sample CSS to show the drag and drop area:

.drag-and-drop-border {
  vertical-align: middle;
  text-align: center;
  border: double;
  background-color: lightblue;
  width: 400px;
  height: 100px;
}

Event handler implementations

export class SomeComponent implements OnInit {

 onFilesDropped(files: File[]): void {
    if (files.length) {
      // Use for example the uploadService to upload files to ACS
      console.log('# of files dropped: ', files.length);
    }
  }

  onFolderEntityDropped(folder: any): void {
    if (folder.isDirectory) {
      // Use for example the uploadService to upload folder content to ACS
      console.log('Folder dropped: ', folder);
    }
  }
