Answer 1

It is not clear what kind of form you are opening in Excel by clicking on the ribbon button. But let's suppose it is a windows form. If so, you can take a look at the Walkthrough: Performing a Drag-and-Drop Operation in Windows Forms .

To perform drag-and-drop operations within Windows-based applications you must handle a series of events, most notably the DragEnter, DragLeave, and DragDrop events. By working with the information available in the event arguments of these events, you can easily facilitate drag-and-drop operations.
