Is it possible to have the RadCalendar inside the RadDatePicker and RadDateRangePicker to have a different theme than the RadDatePicker and the RadDateRangePicker?

I tried setting this within the RadDatePicker control's xaml:

<telerik:RadDateTimePicker.CalendarStyle>
    <Style TargetType="telerik:RadCalendar">
        <Setter Property="telerik:StyleManager.Theme"
                Value="Windows11" />
    </Style>
</telerik:RadDateTimePicker.CalendarStyle>

...but it has no effect.

https://docs.telerik.com/devtools/wpf/controls/raddatetimepicker/styles-and-templates/styling-raddatetimepicker

After extracting the default style for RadDateTimePicker to the resource file to my application (as mentioned in the above page.), RadDateTimePicker is not working as expected.

For current month it picks up the correct date that is selected in the calendar. But for previous months and next months, it is picking up different date than selected.

Hi all!

I have an event which triggers an async loading task in which I change data which is bound to the RadCalendar.

In my development environment I never had any issues but users on RDS-Server have. This is the stack-trace from there log:

Do I have to take care some how of the binding or how can I catch this to prevent app crash?

Thanks for help!!!!!!

     Hi,

I'm facing an issue with RadCalendar placed inside a RadDocking control. The DisplayDateChanged event is called whenever I dock or undock the calendar from the docking control. I've bound a data refresh command to the said event, but dock/undock causes the command to be fired without being needed.

Here is the Xaml:

<telerik:RadCalendar>

<behaviors:EventTrigger EventName="DisplayDateChanged">
       <behaviors:InvokeCommandAction Command="{Binding Path=RefreshDataCommand}" CommandParameter="{Binding                        ElementName=ctrlCalendarView, Path=DisplayDate}">
</behaviors:InvokeCommandAction>
</telerik:RadCalendar>

RefreshDataCommand is coming from ViewModel.

What the issue is this, please look into the matter.

Thanks.

Hi Progress Team,

I added a RadCalendar component to my project but when changing the base week of this 2x2 grid calendar the weeknumbers stay the same all the time. Have I missed something here? How do they update? I used the following code for the XAML definition:
