CommitDraggingEvent is called too early

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Hi!

If I drag & move an event, it is of interest to cancel the movement when the user drops the item. That is, I have to catch the drop before CommitDraggingEvent is being called. I think I have tried everything now. My last attempt was to somehow overload all CXTPCalendarView-derived classes, but with no success.

Please, help me out on this one! How do I cancel a dragmove _after_ the drop?

	Let me ask you why do you need this? Because generally users have tasks to restrict dragging of some events or restrict dragging to some places (dates or AllDayEvents area, etc). For this purpose (and not only for dragging) Calendar sends special notification XTP_NC_CALENDAR_BEFORE_EVENT_EDIT_OPERATION which allows you customize editing like dragging, copy/paste, resizing events ... But if you really want what you are asking for -- derive from CXTPCalendarControl and catch message CXTPCalendarControl::OnLButtonUp(). Default implenentation throws it to views, days, ... Check if you are in dragging mode and need to cancel dragging, just call m_pActiveView->CancelDraggingEvent(); before calling base CXTPCalendarControl::OnLButtonUp(). (or do not call base implementation at all). -- WBR, Serge

	Hi, I want users to be able to drag&drop events. Still, the users of this application will be quite inexperienced. It is therefore important to double-check with the user, that the event should indeed be moved. Thanks for your solution.
