Rad Scheduler - Suitability Question

[Mike]

I am wondering whether the RAD Scheduler could be made to work in the scenario below.  The documentation leads me to think that the scheduler is intended primarily to track schedules for one person at a time.  Eg, I can set my schedule up, and you can set yours up, but the two must be viewed separately.

This scenario is for a school which needs to make schedules for students, staff, locations, and groups of the three.

So, for example, the scheduler should drop two students and one staff member into a 45 minute meeting in room A on a given day at 10:45.  On the same day, it should drop different students and staff members into a different room at the same time.  If someone tries to put the same student in different places at overlapping times, it would be rejected.

I cannot tell from skimming the documentation whether this is feasible with the scheduler.  As mentioned above, it looks like a tool for dealing with one individual, not with groups resources.

Thanks

Hi Mike,

I am glad to inform you that RadScheduler supports the functionality which you desire and its implementation is quite simple in fact. Please, check the Resource Grouping example.
 
Also, to limit the number of concurrent appointments, please use the following code:
C#

protected bool ExceedsLimit(Appointment apt)
{
    int appointmentsCount = RadScheduler1.Appointments.GetAppointmentsInRange(apt.Start, apt.End).Count;
    return (appointmentsCount > AppointmentsLimit - 1);
}

protected bool HasSameResource(Appointment apt, RadScheduler scheduler)
{
    foreach (Appointment otherApt in RadScheduler1.Appointments.GetAppointmentsInRange(apt.Start, apt.End)) {
        foreach (Resource otherAptRes in otherApt.Resources.GetResourcesByType(scheduler.GroupBy)) {
            foreach (Resource res in apt.Resources.GetResourcesByType(scheduler.GroupBy)) {
                if (otherAptRes.Key.Equals(res.Key)) {
                    return true;
                }
            }
        }
    }
    return false;
}

protected void RadScheduler1_AppointmentInsert(object sender, Telerik.Web.UI.SchedulerCancelEventArgs e)
{
    if (RadScheduler1.SelectedView == SchedulerViewType.ResourceView) {
        if (ExceedsLimit(e.Appointment) & HasSameResource(e.Appointment, RadScheduler1)) {
            Label1.Text = "Another appointment exists in this time slot.";
            e.Cancel = true;
        }
    }
    else {
        if (ExceedsLimit(e.Appointment)) {
            Label1.Text = "Another appointment exists in this time slot.";
            e.Cancel = true;
        }
    }
}

VB.NET

Protected Function ExceedsLimit(ByVal apt As Appointment) As Boolean
    Dim appointmentsCount As Integer = RadScheduler1.Appointments.GetAppointmentsInRange(apt.Start, apt.[End]).Count
    Return (appointmentsCount > AppointmentsLimit - 1)
End Function

Protected Function HasSameResource(ByVal apt As Appointment, ByVal scheduler As RadScheduler) As Boolean
    For Each otherApt As Appointment In RadScheduler1.Appointments.GetAppointmentsInRange(apt.Start, apt.[End])
        For Each otherAptRes As Resource In otherApt.Resources.GetResourcesByType(scheduler.GroupBy)
            For Each res As Resource In apt.Resources.GetResourcesByType(scheduler.GroupBy)
                If otherAptRes.Key.Equals(res.Key) Then
                    Return True
                End If
            Next
        Next
    Next
    Return False
End Function

Protected Sub RadScheduler1_AppointmentInsert(ByVal sender As Object, ByVal e As Telerik.Web.UI.SchedulerCancelEventArgs)
    If RadScheduler1.SelectedView = SchedulerViewType.ResourceView Then
        If ExceedsLimit(e.Appointment) And HasSameResource(e.Appointment, RadScheduler1) Then
            Label1.Text = "Another appointment exists in this time slot."
            e.Cancel = True
        End If
    Else
        If ExceedsLimit(e.Appointment) Then
            Label1.Text = "Another appointment exists in this time slot."
            e.Cancel = True
        End If
    End If
End Sub
