How do I make it so that when you right-click on an event that event is selected? I want to show a popup menu after the event is selected with a right-click. Is there any reason to use the ContextMenu event over the mousedown/mouseup events to show a popup menu?
Thanks

Hi,
To determine an event under the mouse cursor you can use method HitTest(). For example see Calendar VB sample, CalendarControl_ContextMenu handler.
You can use MouseUp event as well as ContextMenu.

btw, you can also do any kind of selection inside those methods.

This is what I was already doing, but I thought I was oing it wrong because there is a problem. On the mousedown event I have:
xtmCalendar.ActiveView.UnselectAllEvents ' without this the event will never be selected, subsequent right clicks or not.
Set HitTest = xtmCalendar.ActiveView.HitTest
If Not HitTest.ViewEvent Is Nothing Then
xtmCalendar.ActiveView.SelectViewEve nt HitTest.ViewEvent, True
End If
And I show the popup menu on mouseup.
The problem is that the event is not selected until the second time I right-click on the event. The first time I right click on the event (when it hasnt been selected), the event is not visibly selected on mouse down, and on mouse up it doesn't show either (the popup does show though). The only time it shows is when next I right click on the event (not having clicked anywhere else), and then it does work correctly - the event is selected on mouse down, and the popup is shown on mouse up.
What appears to be happening though is that its not exactly the second time I right click - it is the next time I right click ONE SECOND after the first right click. So I can right click as many times as I like, the selection will only happen 1 second after the first right click (e.g. say i keep right clicking many times, the selection will only happen on the first click that occurs one full second after the initial right click).
Here is a sample that reproduces it: uploads/dajv/2005-12-06_174649_xcb_calendar_bug_2.rar - 2005-12-06_174649_xcb_calendar_bug_2.rar

Please note that some simple Calendar operations like SelectViewEvent does not redraw a control's window in order to avoid blinking when executed in groups (like selecting a number of events).
So, just call xtmCalendar.RedrawControl after changing a selection (at the end of this method).

That would have been useful to know before and would have saved alot of time.
Thanks.
