Hi,

We are currently evaluating your scheduling control (Version: 5.4.1.20046).
We have the issue when we define an Appointment which has an EndTime which is past the Calendar.GetLastDate() it is not displayed.
We have a custom paint EventHandler which evaluates GetVisibleItems(). As mentioned before items which exceed the visible range are missing - and therefore not painted

Any idea is highly appreciated.

Thanks
Thomas

Hi Meppy,

Sorry if I did not make myself clear enough. The problem is that calendar.GetVisibleItems() does not return the Appointment. And because of that I do not trigger my Appointment.Paint() event.

I did some more investigation.
The problem is not exactly when the Appointment is exceeding the "calendar.GetFirstDate()" or the "calendar.GetLastDate()".
The Problem is when the Appointment takes longer than the TimeSpan of "lastDate - startDate".
Meaning I show a complete day in the "CalendarView.Timetable" from 0:00 till 24:00. If I have an Appointment which starts yesterday at 20:00 and finishes today at 9:00 it works fine. But if the same Appointment finishes by 22:00 it is not returned by the GetVisibleItems().

Hope that makes it a little clearer,
Thomas

Hi Meppy,

Your suggestion makes a big difference! Please see the attached screenshots.
You have indicated that the "additional" item might be not visible, but "Visible" is true.

I am not sure if I will be able to post a sample project today - it is already friday afternoon. But latest next week!

Thank you,
Thomas

Hi again,

Are you sure that the item is actually visible inside the current viewport? Calendar.GetItemBounds will return an empty rectangle for items that are not currently visible because their bounding rectangles have not been calculated. This will also explain why the item is not included in the GetVisibleItems result. Note, that the Item.Visible property does not necessarily indicate that the item is currently visible on screen. This property specifies whether the item should be visible if the item is inside the currently displayed time interval and is true for all items unless explicitly assigned by the user.

The item might not be visible due to grouping. For example, if the item is related to a resource, which is not included in the resources the view is currently grouped by, the item will not be displayed. Let me know if you are using grouping and if this is the case, what are your grouping settings.

I suspect it might be the following:

By default items longer than one day are displayed in the all-day header of the Timetable view (above the column cells and just below the regular column header). This header however is not displayed in all themes. For example, it is not displayed in the default Standard theme. When an item is longer than one day and the all-day header is not enabled, the item is simply not displayed. If this is the case, you have two options:

1) You can enable the all day header, either implicitly by selecting a theme (such as Vista) where it is enabled, or explicitly, by setting Calendar.TimetableSettings.ShowDayHeader to Enabled.

2) You can prevent items longer than 1 day from being placed in the all-day header by setting Calendar.TimetableSettings.EnableDayItems to Disabled.

I hope this helps.

Regards,
Meppy

Hi Meppy,

I hope I can rely on your great support once more. I have the items in the calendar now. But I do not understand why the "extended" part of the item has a different color and mouse hover behaviour.
The one Appointment I am referring to, starts at the 8th of December and lasts till the 11th of December. Text: "Administrator: 001".

Thank you,
Thomas

Hi Meppy,

You are presuming correct "you are not using the built-in custom-drawing functionality".
I will give it a try on Monday.

Have a nice weekend!
