After switching our project from 15.1.8 to 15.2.3 the object DateEditCalendar is missing in the namespace DevExpress.XtraEditors.Controls.
DateEditCalendar missing in DevExpress.XtraEditors.Controls
Answers approved by DevExpress Support
Hello,
Since we have modified the DateEdit control in the 15.2 version, you don't need to create VistaPopupDateEditForm and VistaDateEditCalendar class descendants.
Instead, create PopupDateEditForm and CalendarControl class descendants and override the PopupDateEditForm.CreateCalendar and CalendarControl.OnMouseUp methods.
I've created a sample to illustrate how to achieve the required result. Please try it and let me know if it meets your requirements.

Hello Oliver,
Replace that line with the following one in the CustomCalendarControl's constructor:
Visual BasicMe.VistaCalendarViewStyle = DevExpress.XtraEditors.VistaCalendarViewStyle.YearView
I hope you find this information useful.

> Would you please clarify why you need to use the DateEditCalendar class?
I don't like to be forced to change my implementation after I update a framework I use. Nobody likes it. You made us to spend time on something that we don't want to do and doesn't give us benefits. It should be backward compatible. This is why I need it. Sorry, but this is how I see it.
Hello,
We agree that nobody likes changing the code after upgrading when it worked correctly before the upgrade. Yes, as a developer, I completely understand how frustrating this can be.
That's why even though we received many requests from our customers, we did our best to avoid internal modifications in DateEdit. However, when analyzing our customer requests and the solutions we provide involving DateEdit, we came to the conclusion that we had to make this change. Otherwise, with customer requirements growing, these solutions become more and more complex and as a result, such projects will be very difficult to maintain. Moreover, there were many popular scenarios that couldn't be implemented with the old architecture. Some of them required heavy customization or creating custom DateEdits. We collected the most popular of such scenarios and supported them out of the box to simplify the process of creating descendants.
Our modifications barely change the public API. So, for those users who don't have custom editors, this change should not be noticeable. Nevertheless, we understand that custom DateEdits may be broken. Thus, we did our best to minimize the difference between old and new DateEdit's structure. You no doubt understand, it's impossible to add new features without internal modifications.
Here are several of the most popular features that previously required a lot of coding and now are supported out of the box:
DateEdit - How to select multiple dates
DateEdit - How to enlarge dates in calendars on hovering with the mouse
How to add notes to a DateEdit calendar
How to change the Today date for the DateEdit.
It is likely that the functionality you implemented in the DateEdit's descendant is easier to implement now.
In any case, if you have any issues with upgrading your code, just let us know. We will be happy to assist you with this task.
The same problem with the object VistaDateEditCalendar
Hi Holger,
We have redesigned our DateEdit control. Would you please clarify why you need to use the DateEditCalendar class? Describe your scenario in greater detail. Perhaps, our redesigned DateEdit supports the required functionality out of the box.
I hope to hear from you soon.
See our sample code attached in this comment.
