How to detect when a Form is being dragged?

Question

I have a Form object with a title bar displayed.

I need a pure managed way(P/Invoke-free, both Mono and .NET compatible, preferrably a .NET 2.0 API) to detect when the FORM itself starts being dragged, changes location and when it is dropped(not any content).

I did this in the past in Mono but I don't remember how anymore and I don't know if my solution was MS.NET-compatible...

If anyone could provide an example, three event names for me to google more details or point me to a relevant StackOverflow question, I would greatly appreciate. So far, my search has returned no relevant results...

Answer 1

Are you talking actual drag-drop operation here, or when the user moves the form? If it is the movement itself, you might be able to use the ResizeBegin event, which is raised when the user starts to move the form. This together with LocationChanged and ResizeEnd should cover your needs. However, the ResizeBegin and ResizeEnd events are (of course) also raised when you start and end resizing the form, not only when you are moving it.
