Remarks

When the UploadAdvancedModeSettings.EnableDragAndDrop property is set to true, ASPxUploadControl allows end-users to add files to upload lists by dragging them to a control. By default, end-users can drop files to a drop zone to add them to the upload control file list.

Use the ExternalDropZoneID property to specify an external zone (HTML element) where end-users can drop a file to add it to the upload control file list. You can also specify a list of control IDs separated by the semicolon ( ; ) sign.

To learn more about the drag and drop functionality of the upload control, see the Drag and Drop topic.
