Thank you for contacting Syncfusion support,
Can you please explain whether you are asking in WPF platform? If so please find the below solution for your requirement
In our WPF CalendarEdit control, we can change the visibility of next month and previous month dates using the Boolean properties “ShowNextMonthDays” and “ShowPreviousMonthDays” respectively. We have prepared a sample by disabling these two properties and it will display only the current month dates.
If your requirement is different from our solution please provide more information about your requirement.
Please download the sample form the below link.
