You can configure the Treeview component to accept files dropped from other applications. You use the CanDropFile column to control which nodes will accept files.
The component has two new calls:
@Action = 'VerifyFiles'
is made when the files are dropped, but before uploading starts. It can optionally refuse the drop, based on name, size, or content type.@Action = 'SaveFiles'
is made once the files have been uploaded.
