This is an issue in RadCalendar when we use Multiple month view. This problem can be reproduced in the WPF demo examples.
RadCalendar -> Selection range and Constraints
1. Set the radcalendar columns = 3.
2. Select a date in the month of May. For example select May 8th.
3. Click on the next button in navigation to move to next set of months. It should ideally have shown June, July and August after March, April and May. But it skips 2 months and goes directly to August, September and October.
4. If int he same way you select a date in April and navigate to next three months. It skips one month(June) and shows July, August and September
This happens if we have set the columns value to greater than 1. I guess in trying to set the 3 months to show in the calendar the selected date/month depending on if its the 2nd or the 3rd month in the sequence shown causes the calendar to skip 1 or 2 months respectively.
This can be replicated on one your demo projects. Let me know if you need a project from me.
I couldnt find a bug report or a question in the telerik forum on this topic. If its not reported before this should be a simple fix for you guys.
Introduce a mechanism for enabling/disabling the animation executed when changing the views - month, year, etc. Currently, there is an animation executed by default which cannot be turned off.
Available in the 2017 R1 Release (2017.1.117). More information you can find in following help article: http://docs.telerik.com/devtools/wpf/controls/radcalendar/features/globalization
Currently, the maximum that is displayed in the calendar is 1/1/3000 and the minimum is 1/1/1000. However, you can set a value that is bigger or smaller in the SelectedDate property. Introduce an API that allows changing those dates.
Canceling the changing of the value bound to the SelectedDate causes the new clicked date to by highlighted incorrectly. The new selected date should not be highlighted since the bound value has not been changed to that value. The issue can be observed in RadCalendar, RadDatePicker and RadDateTimePicker controls.
You can check the following blog post showing how you can easy add your custom SelectedDates dependency property: http://www.telerik.com/blogs/using-the-multiple-selection-of-the-radcalendar-control-for-silverlight-and-wpf-with-mvvm .
When DateSelectionMode is set to Month and SelectionMode is set to Multiple or Extended selecting multiple months should be available.
RadCalendar should have property which switches between single raise of the SelectionChanged event when multiple items are selected and multiple raises (on each element hover) when multiple items are selected. When the property is in single raise mode, the event should be raised only once on MouseLeftButtonUp. In this case the SelectedItems collection should be also updated at once.
The same goes for the years.
When DayTemplateSelector that sets template with IsEnabled = False is set at runtime, no calendar buttons can be selected - even these that does have IsEnabled = True. Available in LIB version 2016.1.418, it will be also available in the 2016 R2 release.
When clicking fast through days inside RadCalendar the SelectionState does not disappear when another day is selected.The issue is reproduced only in the selection mode. Available in LIB version 2015.3.1123, it will also be available in the 2016 Q1 release.
Available in LIB version 2014.3.1319 as it will be also available in the 2015 Q1.
When ran on 1366x768 resolution and the DPI is set to higher value than the default one, in some cases the control is not rendered correctly.
