Drag and Drop a File as Link to Outlook

Question

I have a requirement to drag and drop a file node from a C# treeview to new email in outlook. The file has to be added as a link in the email. Is there anyway we can capture the drop event of outlook so that we can do custom logic to add file as link?

Thanks.

Answer 1

No, but make the drag/drop source in your treeview provide the drag/drop data in the file format.

Answer 2

Yes i tried using DoDragDrop in my treeview but that adds the attachment as file. We need to provide a prompt to the user to add attachment as file or as link in email. I am trying to use BeforeAttachmentAdd event to prompt user if that may work.

Problem is that DoDragDrop method requires a valid file path (saved on local disk) and doesn't take file URL. I would like to avoid the download of the actual file until BeforeAttachmentAdd method.

Only if you do CF_HDROP.  You can also do CFSTR_FILEDESCRIPTOR/ CFSTR_FILECONTENTS
