I have discovered a bug that appears when a RadScheduleView is used with the ScheduleViewStyleSelector to style the appointments and the theme is changed.

Steps to reproduce:

1. Setup a WPF project.
2. Use implicit styles with a theme (e.g. Office_Black).
3. Create a possibility to change the theme on runtime (e.g. to Fluent). (https://docs.telerik.com/devtools/wpf/styling-and-appearance/how-to/styling-apperance-themes-runtime)
4. Create a dialog with a RadScheduleView that uses a custom ScheduleViewStyleSelector as AppointmentStyleSelector. (https://docs.telerik.com/devtools/wpf/controls/radscheduleview/styles-and-templates/appointment-style)
5. Create at least one appointment.
6. Start application.
7. Change theme at runtime.

Result: The "old" appearance of the appointments stays after changing the theme.

Expected behavior: The appearance of the appointments changes according to the new theme.

 

I have attached a solution with the described behavior and an image of the outcome.

A XamlParseException is raised when binding to the ShowAppointmentDeleteButton property of the RadScheduleView. 

 

Current, there is no public API that let you know when the active view definition is changed. Expose an event for this.

Now, you can listen for changes in the active view definition by overriding the OnActiveViewDefinitionChanged method of RadScheduleView.

I need an overview of the appointments in the range of multiple days of several resources (let's say, employees).

For this, the agenda view would be perfect if it shows the days as rows but the grouped resources as columns.

In the current version it as possible to group by resources in the agenda view, but the single resources can be displayed only as rows along with the days. This way an overview is not possible. At now, I have to put several ScheduleView controls side by side, each displaying a single resource, to achieve the desired view.

Therefore I want to engage a feature request:

Please, in the agenda view, allow a grouping of resources with arranging them in a horizontal way, while the days stay arranged in a vertical manner.

 

We can create an SDK example that demonstrates how RadScheduleView can be populated from PostgreSQL DataBase.

 

There is a fixed value of 16px set for the Height of the GroupHeader. Thus, when a FontSize bigger than 16px is set, the Text is cut off as the GroupHeader is not resized. The workaround is to predefine the GroupHeaderContentTemplateSelector and remove the fixed Height that is set through it. 

<telerik:GroupHeaderTemplateSelector x:Key="GroupHeaderContentTemplateSelector">
                <telerik:GroupHeaderTemplateSelector.HorizontalTemplate>
                    <DataTemplate>
                        <ContentPresenter Content="{Binding FormattedName}"  Margin="4" />
                    </DataTemplate>
                </telerik:GroupHeaderTemplateSelector.HorizontalTemplate>

                <telerik:GroupHeaderTemplateSelector.VerticalTemplate>
                    <DataTemplate> 
                            <ContentPresenter Content="{Binding FormattedName}" Margin="4" VerticalAlignment="Top">
                                <ContentPresenter.LayoutTransform>
                                    <RotateTransform Angle="-90" />
                                </ContentPresenter.LayoutTransform>
                            </ContentPresenter> 
                    </DataTemplate>
                </telerik:GroupHeaderTemplateSelector.VerticalTemplate>
 </telerik:GroupHeaderTemplateSelector>

When the RecurrenceFrequency is set to Year. The GetOccurrences() method of the RecurrencePattern does not respect the Interval property.

The direction of EditAppointmentDialog, RecurrenceChoiceDialogStyle etc. is always LeftToRight even if the ScheduleView itself is RightToLeft.

Currently, separate calendars are created for each time zone.

Currently when the RadScheduleView is grouped by some resources, all of them are displayed at once and each is in a separate calendar. We should consider introducing an option for the users to switch between the resource that is visible.

Add an API similar to the SlotSelectionBehavior that allows you to customize the highlighted slot. This is the slot that is colored (usually in gray) when you mouse over the timeline of the RadScheduleView control.

Currently, if the ShowAllDayArea property of the ViewDefinition is True, appointments longer than 24 hours are shown in the AllDayArea. We should add an option for such appointments to be shown in the normal slots. 

Here is the link to the example in the XAML SDK Repository:

https://github.com/telerik/xaml-sdk/tree/master/ScheduleView/Database

When an appointment is double clicked, the edit appointment dialog is shown. When the escape button is clicked, the edit appointment dialog is closed. When the above 2 actions are performed in quick succession, the appointment disappears.
