Topic: Drag Occurence

hi,

I have a master event and a recurrence pattern, which means that there is a series of occurences.

If I click and drag one of the occurences to another location, the occurence turns into an exception with a new date and time. I have stored this data in the database.

Note that the exception has a different date/time.

When I load the form on which my calendar is a next time.. I need to make my exception replace the occurence.. and have the exception represented on the new "date/time"

Can I have a sample code that deals with that also please, because I really need it and the representation of the exception is still a problem for me.

Hi WaaZ,

Please find some more description on times below:

1. Normal event and occurrence event have Start/End times.

2. Exception event has Start/End times and Start/End times of the occurrence (RExceptionStartTimeOrig, RExceptionEndTimeOrig).

MakeAsRException performs 2 actions:
- change recurrence state to exception
and
- copy times:
    RExceptionStartTimeOrig = StartTime
    RExceptionEndTimeOrig = EndTime

This mean that for an exception you have to store 4 values of time (not 2):

    StartTime
    EndTime
    RExceptionStartTimeOrig
    RExceptionEndTimeOrig

There are 2 ways to restore exception time properties:

1. ------------------------------------------------------------ ---------------------
    excepEv.StartTime = <original ocurrence start time>
    excepEv.EndTime = <original ocurrence end time>

    excepEv.MakeAsRException() // copy times to RExceptionStartTimeOrig, RExceptionEndTimeOrig

    excepEv.StartTime = <new exception start time>
    excepEv.EndTime = <new exception end time>

2. ------------------------------------------------------------ ---------------------
    excepEv.MakeAsRException()

    excepEv.RExceptionStartTimeOrig = <original ocurrence start time>
    excepEv.RExceptionEndTimeOrig = <original ocurrence end time>

    excepEv.StartTime = <new exception start time>
    excepEv.EndTime = <new exception end time>

Hi again,

I click and drag an occurence and in the Event handler CalendarControl_EventChanged(object sender, AxXtremeCalendarControl._DCalendarControlEvents_EventChangedEvent e), I get hold of e.eventID.

The following code returns null;

CalendarHitTestInfo HitTest;

HitTest = CalendarControl.ActiveView.HitTest();

HitTest.ViewEvent -- .ViewEvent is null

And also the following returns null:

CalendarControl.DataProvider.GetEvent(e.eventID);

Can you please tell me how I can get hold of the new exception created and the new date.

Thnks

WaaZ

Something like following:


g_LastEventID;
 
EventChanged (e)
{
    g_LastEventID = e.eventID;
}
 
PatternChanged (e)
{
    pPattern =  CalendarControl.DataProvider.GetRecurrencePattern(e.patternI D)         
    // iterate pPattern.Exceptions 
    // for
    // pPattern.Exceptions.EventID == g_LastEventID

}
