Rad Scheduler - how to set only current appointment height and width and all other appointment height and width as it is ?

[John]

I was not able to set custom appointment height and width at runtime So, I was used TimelineAppointmentsPresenter class and ResolveOverlappingAppointments method using possible to display manually height and width at runtime.But I was faced one problem our appointment data is 10,00,000 When I was  create new appointment and set only new appointment height and width set. then all other appointment height and width default set(Not  Consider when previously set).So,every time set all appointment height and width.So,how to set only current appointment height and width and all other appointment  are as it is ?

Because it's decrease performance.

----Code

 Protected Overrides Sub ResolveOverlappingAppointments(availableSize As SizeF)
        
Dim arrangedAppointments As New List(Of AppointmentElement)()
  
        AppointmentElements.AsEnumerable().Where(Function(e) e.Visibility <> ElementVisibility.Collapsed).
            All(Function(o)
                  
    End Sub

End Class

Hello John, 

Thank you for writing.  
 
By design, RadScheduler's appointments are sized according to the time slot they take. In timeline/month view, for example, the AppointmentHeight property is purposed to control the height. It is not expected to have appointments with different height and width. However, you can handle the AppointmentFormatting event and specify the height. As to the width, it depends on the width of the column to which the appointment belong:

public RadForm1()
{
    InitializeComponent();

    this.radScheduler1.ActiveViewType = Telerik.WinControls.UI.SchedulerViewType.Timeline;
    this.radScheduler1.AutoSizeAppointments = true;

    this.radScheduler1.AppointmentFormatting+=radScheduler1_AppointmentFormatting;
    for (int i = 0; i < 10; i++)
    {
        this.radScheduler1.Appointments.Add(new Appointment(DateTime.Now.AddDays(i),TimeSpan.FromDays(1),"Event" + i));
    }

}

private void radScheduler1_AppointmentFormatting(object sender, SchedulerAppointmentEventArgs e)
{
    if (e.Appointment.Summary.Contains("3"))
    {
         e.AppointmentElement.MinSize = new Size(0,100);
    }
}
