RadSheduler - FindById helper function

[Roman]

Hi!

I'm new in ASP.NET, so excuse me for stupid question, but i really don't understand.
I tried to work with RadSheduler by this tutorial. And everything is ok, but i don't understand, why when i ran an application, it gives me an error "The name 'appointments' does not exist in the current context" =/

Best wishes,
Roman

Hi Roman,

Can you send us a small working demo of the problem which we can test locally? To attach files, you will need to open a support ticket.

Hi Roman,

Thanks for the demo. It helped us find out what the problem is. In the FindById helper function, "appointments" should be with capital A:

 private AppointmentInfo FindById(string ID)
    {
        foreach (AppointmentInfo ai in Appointments)
        {
            if (ai.ID == ID)
            {
                return ai;
            }
        }
        return null;
    }

Appointments is the list defined by this code:

private List<AppointmentInfo> Appointments
        {
            get
            {
                List<AppointmentInfo> sessApts = Session[AppointmentsKey] as List<AppointmentInfo>;
                if (sessApts == null)
                {
                    sessApts = new List<AppointmentInfo>();
                    Session[AppointmentsKey] = sessApts;
                }

                return sessApts;
            }
        }

Thank you very much!

Excuse for my persistence, but only have understood with one problem as I had another. I tried to understand with her, reading lessons and looking through similar errors at a forum, but it has not helped me. Can you help me once more. My error:

Both DataSource and DataSourceID are defined on 'RadScheduler1'.  Remove one definition.

Hi Roman,

The error message describes what the problem is. In Shedulet.ascx you set the DataSourceID:

<telerik:RadScheduler ID="RadScheduler1" runat="server" DataEndField="End"
DataKeyField="ID" DataRecurrenceField="RecurrenceRule"
DataRecurrenceParentKeyField="RecurrenceParentID" DataSourceID="SqlDataSource1"

And in code behind you set: RadScheduler1.DataSource = Appointments;

You should either set the DataSource or the DataSourceID property, but you cannot set both.


Kind regards,
