    Is it possible to change the height of appointments in the schedulers timeline view?

    Either a fixed size or a "fill" option - where the appointment would fill the day/resource cell- would be great. In the case of the fill option, multiple appointments would divide available space between them until such time as the text becomes unreadable, then they scroll.

    If either of these options are possible, can someone please point me in the right direction so I can implement it on my control?

    Hello Karl,

    Thank you for your question.

    There is an AppointmentHeight property in the SchedulerTimelineViewElement which you can use to set fixed height for all appointments. You can set this property in the VisualStyleBuilder as it is demonstrated on the attached screenshot. In case you want to dynamically calculate the value of this property, you can also set it via the following code:
    SchedulerTimelineViewElement timeline = this.radScheduler1.SchedulerElement.ViewElement as SchedulerTimelineViewElement;
    if (timeline != null)
        timeline.AppointmentHeight = value;

    I hope you find this useful. Feel free to ask if you have any additional questions.

    Kind regards,

    Is there a way to set the AppointmentHeight in GroupedByResource mode when in TimeLineView ?

    Because when using the code above, SchedulerTimelineViewElement returns null.

    Here's the code I'm using :


    01.For i = 0 To pDataSetRessources.Count - 1
    02.   Dim lMachine As New Resource()
    03.   lMachine.Id = New EventId(pDataSetRessources.Item(i).Id)
    04.   lMachine.Name = pDataSetRessources.Item(i).Nom
    05.   lMachine.Color = If(i Mod 2 = 0, Color.White, Color.Gray)
    07.   Me.RadScheduler_PlanningOf.Resources.Add(lMachine)
    10.RadScheduler_PlanningOf.GroupType = GroupType.Resource
    14.Me.RadScheduler_PlanningOf.ActiveViewType = SchedulerViewType.Timeline
    17.           Dim timelineViewElement As SchedulerTimelineViewElement = _
    18.              TryCast(Me.RadScheduler_PlanningOf.SchedulerElement.ViewElement, _
    19.                  SchedulerTimelineViewElement)
    21.           If Not IsNothing(timelineViewElement) Then ' Returns nothing :'(
    22.               'No Way
    23.               timelineViewElement.AppointmentHeight = 200
    24.               'If Only ...
    25.               timelineViewElement.Presenter.AppointmentHeight = 200
    26.           End If



    P.S. I've seen there's classes dedicated to GroupedByResource that might help like
    SchedulerDayViewGroupedByResourceElement > SchedulerDayViewElement
    But no such class for TimeLineView

    Hello David,

    Thank you for writing.

    Here is a sample code snippet demonstrating how to specify the AppointmentHeight property for each SchedulerTimelineViewElement associated with a resource: 
    Sub New()
        Dim colors() As Color = {Color.LightBlue, Color.LightGreen, Color.LightYellow, Color.Red, Color.Orange}
        Dim names() As String = {"Alan Smith", "Anne Dodsworth", "Boyan Mastoni", "Richard Duncan", "Maria Shnaider"}
        For i As Integer = 0 To names.Length - 1
            Dim resource As New Telerik.WinControls.UI.Resource()
            resource.Id = New EventId(i)
            resource.Name = names(i)
            resource.Color = colors(i)
        Next i
        Me.RadScheduler1.GroupType = GroupType.Resource
        Me.RadScheduler1.ActiveView.ResourcesPerView = Me.RadScheduler1.Resources.Count
        Me.RadScheduler1.ActiveViewType = SchedulerViewType.Timeline
        Dim rand As New Random
        For index = 1 To 10
            Dim a As New Appointment(DateTime.Now.AddHours(index), TimeSpan.FromHours(2), "A" & index)
            a.ResourceId = Me.RadScheduler1.Resources(rand.Next(0, Me.RadScheduler1.Resources.Count)).Id
        Dim timelineElement As TimelineGroupingByResourcesElement = TryCast(Me.RadScheduler1.SchedulerElement.ViewElement, TimelineGroupingByResourcesElement)
        For Each el As RadElement In timelineElement.Children
            Dim t As SchedulerTimelineViewElement = TryCast(el, SchedulerTimelineViewElement)
            If t IsNot Nothing Then
                t.AppointmentHeight = 50
            End If
    End Sub

    I hope this information helps. Should you have further questions I would be glad to help.
