AppointmentVisibility Property

Returns or sets a value indicating whether appointments are displayed in the user interface.
Syntax
'Declaration
 
Public Property AppointmentVisibility As TimelineViewAppointmentVisibility
public TimelineViewAppointmentVisibility AppointmentVisibility {get; set;}
Remarks

When appointments are displayed, the placement of each appointment is determined by its ownership in conjunction with the value of the OwnerGroupingStyle property.

Note: When the associated UltraCalendarInfo'sAllowAllDayEvents property returns false, the AppointmentVisibility property resolves to 'HideAllDayEvents' when not explicitly set; if the AllowAllDayEvents property returns true, it resolves to 'Show'.

Example
The following code sample demonstrates how to use the properties of the UltraTimelineView control to customize the appearance and behavior for appointments and holidays:

Imports System.Collections.Generic
Imports Infragistics.Win
Imports Infragistics.Win.UltraWinSchedule
Imports System.Diagnostics

    Public Sub InitActivityProps(ByVal control As UltraTimelineView)

        '  Align activities with the PrimaryInterval, so that the
        '  edges of the elements are flush with the time slot borders
        control.AlignActivityWithPrimaryInterval = DefaultableBoolean.True

        '  Set the height of the bar color indicator, and show it
        control.AppointmentDisplaySettings.BarColorIndicatorHeight = 5
        control.AppointmentDisplaySettings.BarColorIndicatorVisibility = TimelineViewBarColorIndicatorVisibility.ShowOnTop

        '  Show continuation arrows for appointments whose start/end time is not visible
        control.AppointmentDisplaySettings.DateTimeContinuationIndicatorVisibility = TimelineViewDateTimeContinuationIndicatorVisibility.Both

        '  Don't display the resolved appointment appearance image to conserve space
        control.AppointmentDisplaySettings.DisplayAppearanceImage = DefaultableBoolean.False
