Unselect a selected appointment

[Craig Gamble]

i have a little function that will loop through an active view and unselect any cells that have been selected

        private void UnselectCells()
        {

            SchedulerMonthViewElement monthView = this.schRates.SchedulerElement.ViewElement as SchedulerMonthViewElement;
            Telerik.WinControls.RadElementCollection childrenCollection = monthView.Children[1].Children;

            foreach (MonthCellElement cell in childrenCollection)
            {
                if (cell.Header.Selected == true)
                {
                    cell.Header.Selected = false;
                }

                if (childrenCollection.IndexOf(cell) == 34)
                { break; }
            }
        }

but i would like something similar to unselect any appointments but cant seem to find a way?? something like the following.......

        private void UnselectAppointments()
        {
            foreach (IEvent appointment in this.schRates.ActiveView.Appointments)
            {

                if (appointment.Selected == true)
                {
                    appointment.Selected == false;
                }
            }
        }

Any help is greatly appreciated,

Cheers,
Craig

Hi Craig Gamble,

Here is a method that will unselect all selected appointments in a month view:

private void UnselectAppointments(SchedulerMonthViewElement monthViewElement)
        {
            if (monthViewElement == null)
            {
                return;
            }
            MonthViewAreaElement monthViewAreaElement = monthViewElement.Children[1] as MonthViewAreaElement;
            if (monthViewAreaElement == null)
            {
                return;
            }

            foreach (RadElement element in monthViewAreaElement.Children)
            {
                AppointmentElement appointmentElement = element as AppointmentElement;
                if (appointmentElement != null)
                {
                    if (appointmentElement.Selected)
                    {
                        appointmentElement.Selected = false;
                    }
                }
            }
        }

This method is used like bellow:

SchedulerMonthViewElement monthViewElement = this.radScheduler.SchedulerElement.ViewElement as SchedulerMonthViewElement;
            this.UnselectAppointments(monthViewElement);

However, I have to warn you that this method will break if the element structure is changed.
That is why we will think of an easier way to select / unselect appointments programmatically.

What about in a DayView?

[Dobry Zranchev]

Hello Carlos,

Thank for contacting us.

You could use the following code snippet to unselect all appointments in the DayView:
 

SchedulerDayViewElement dayViewElement = this.radScheduler1.SchedulerElement.ViewElement as SchedulerDayViewElement;

DayViewAppointmentsTable dayViewAppointmentsTable = dayViewElement.Children[2].Children[0].Children[2].Children[3].Children[1] as DayViewAppointmentsTable;
if (dayViewAppointmentsTable == null)
{
    return;
}

foreach (RadElement element in dayViewAppointmentsTable.Children)
{
    AppointmentElement appointmentElement = element as AppointmentElement;
    if (appointmentElement != null)
    {
        if (appointmentElement.Selected)
        {
            appointmentElement.Selected = false;
        }
    }
}

Do not hesitate to contact us for further questions.

All the best,

Hello Pramod,

Thank you for writing. 

We introduced an improved RadScheduler in Q2 2014 (version 2014.2.617). Now, it provides SchedulerSelectionBehavior which performs selection operations and provides information about the current selection of cells and appointments in RadScheduler. You can use the public API for unselecting a specific appointment. Additional information is available here: http://docs.telerik.com/devtools/winforms/scheduler/fundamentals/scheduler-selection

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