MinimumActivityDuration Property

Returns or sets a value that determines the minimum amount of time that an appointment or holiday must span in order to be displayed by the control.
Syntax
'Declaration
 
Public Property MinimumActivityDuration As TimeSpan
public TimeSpan MinimumActivityDuration {get; set;}
Exceptions
ExceptionDescription
System.ArgumentOutOfRangeExceptionThrown when the value is negative, i.e., less than TimeSpan.Zero.
Remarks

In situations where the cycles generated by the PrimaryInterval are relatively long in duration as compared to the duration of the activities being displayed, it may be desirable to hide activities with short durations from the user; the MinimumActivityDuration property makes this possible. If, for example, the property is set to a value of 30 minutes, appointments whose duration is shorter than 30 minutes do not appear, providing more space in which to display the appointments whose duration is greater than or equal to 30 minutes.

Note: The Seconds and Milliseconds components of the specified value, if any are present, are stripped out at the time of assignment. UltraTimelineView does not recognize units of time that span less than one minute in duration.

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

        '  Display the appointment subject, but not the location
        control.AppointmentDisplaySettings.DisplayLocation = DefaultableBoolean.False
        control.AppointmentDisplaySettings.DisplaySubject = DefaultableBoolean.True

        '  Display the recurrence and reminder indicators on the left
        control.AppointmentDisplaySettings.RecurrenceIndicatorVisibility = TimelineViewRecurrenceIndicatorVisibility.Right
        control.AppointmentDisplaySettings.ReminderIndicatorVisibility = TimelineViewReminderIndicatorVisibility.Left

        '  Display the start and end times, each on either side of the subject
        control.AppointmentDisplaySettings.TimeVisibility = TimelineViewAppointmentTimeVisibility.BothSeparate

        '  Only allow dragging appointments within the same owner
        control.AppointmentDragMode = TimelineViewAppointmentDragMode.WithinSameOwner

        '  Always show appointment tooltips
        control.AppointmentToolTipVisibility = TimelineViewActivityToolTipVisibility.Always

        '  Hide all-day events from the timeline view
        control.AppointmentVisibility = TimelineViewAppointmentVisibility.HideAllDayEvents

        '  Enable automatic creation of appointments when enter key
        '  is pressed on a time slot, and when a time slot is double-clicked
        control.AutoAppointmentCreate = True
        control.AutoAppointmentDialog = True

        '  Only show holidays for the unassigned owner, and never show tooltips for them
        control.HolidayVisibility = TimelineViewHolidayVisibility.ShowForUnassignedOwner
        control.HolidayToolTipVisibility = TimelineViewActivityToolTipVisibility.Never

        '  Only show activities whose duration is at least one hour
        '  allow appointment resizing, but only to a duration of
        '  no less than two hours
        control.AllowAppointmentResize = True
        control.MinimumActivityDuration = TimeSpan.FromHours(1)
        control.MinimumAppointmentResizeDuration = TimeSpan.FromHours(2)
