When I try to call GetApointmentsInRange() I get no results back even though my datasource contains appointments. When I call DataBind() explicitly in Page_Load on my RadScheduler, I get results back... Am I supposed to be calling DataBind() explicitly? I don't call it for RadGrid so I wasn't sure. Any idea why I'm getting no results back in my AppointmentInsert() event?
void
RadScheduler1_AppointmentInsert(
object
sender, Telerik.Web.UI.SchedulerCancelEventArgs e)
{
//Returns no records
var aps = RadScheduler1.Appointments.GetAppointmentsInRange(e.Appointment.Start, e.Appointment.End);
}

Hi Michael Malone,
Are you trying to make a similar project as the "Occupied Timeslots" Demo. You can see how it works.
If you still need help - could you send me your project so I can inspect it and help you?
Thank you!
Kind regards,

I was indeed following that demo except my datasource is created and set in the code-behind from a List of IQuerable objects. It looks like I have to explicitly call DataBind() once my DataSource is set.
void
LoadDataSource()
{
DrAppointment app =
new
DrAppointment();
switch
(RadScheduler1.SelectedView)
{
case
SchedulerViewType.DayView:
DBAppointments = app.GetAll(RadScheduler1.SelectedDate).ToList();
break
;
case
SchedulerViewType.WeekView:
DBAppointments = app.GetAll().ToList();
break
;
case
SchedulerViewType.MonthView:
DBAppointments = app.GetAll().ToList();
break
;
}
RadScheduler1.DataSource = DBAppointments;
RadScheduler1.DataBind();
}

Hello Michael Malone,
Yes, you should call DataBind method of the control after setting DataSource or DataSourceID properties. This is a part of the ASP.NET binding mechanism.

Thanks you... one question though. Why don't I have to call DataBind() with RadGrid?

Hello Michael Malone,
DataBind() method is not called when you are binding to declarative data sources or advanced data binding (NeedDataSource). RadGrid could be binded also with simple data binding.
Please note that it is important not to mix both ways.
