Hello Aditya ,

Suppose you have a resource type with Name="Students". Then you can try the following:

    
             protected void RadScheduler1_FormCreated(object sender, Telerik.Web.UI.SchedulerFormCreatedEventArgs e)  
        
                {  
        
                    if (e.Container.Mode == Telerik.Web.UI.SchedulerFormMode.AdvancedEdit || e.Container.Mode == Telerik.Web.UI.SchedulerFormMode.AdvancedInsert)  
        
                    {  
        
                        Session["CurrentAppointmentID"] = e.Appointment.ID;  
        
                        RadComboBox studentsCB = e.Container.FindControl("ResStudents") as RadComboBox;  
        
                        studentsCB.BackColor = System.Drawing.Color.Red;  
        
                        studentsCB.SelectedIndexChanged += new RadComboBoxSelectedIndexChangedEventHandler(studentsCB_SelectedIndexChanged);  
        
                        studentsCB.AutoPostBack = true;  
        
                    }  
        
                }  
        
                void studentsCB_SelectedIndexChanged(object o, RadComboBoxSelectedIndexChangedEventArgs e)  
        
                {         
        
                    Appointment currentapp = RadScheduler1.Appointments.FindByID(Session["CurrentAppointmentID"]);  
        
                    Appointment appToUpdate = currentapp;  
        
                    appToUpdate.Subject = "modified";  
        
                    foreach (Resource res in RadScheduler1.Resources.GetResourcesByType("Students"))  
        
                    {  
        
                        if (e.Text == res.Text)  
        
                            appToUpdate.Resources.Add(res);  
        
                    }  
        
                    RadScheduler1.UpdateAppointment(appToUpdate, currentapp);  
        
                    RadScheduler1.ShowAdvancedEditForm(currentapp);        
        
                }

Is this what you need?

Its kind tough to build a working version of the project. Here is what I am doing

I have 4 items in the resource collection namely Resources,Type,Patients and Status. However when I do a e.Appointment. only Resources shows up in the intellisense. I am assuming because it treats Resources as a collection. This statement returns a value of 1 e.Appointment.Resources.Count and when I do a ResourceCollection val = e.Appointment.Resources; val contains only Resources. It almost seems as if the resource collection does not know that the other items exist ?

Hope this helps,

Aditya

So that is exactly how I have defined my resources. Now as suggested by you when I try to do the following

Line 1:RadComboBox patientsCB = e.Container.FindControl("ResPatients") as RadComboBox;

Line 2: patientsCB .SelectedIndexChanged += new RadComboBoxSelectedIndexChangedEventHandler(patientsCB _SelectedIndexChanged);

Line 3: patientsCB .AutoPostBack = true;

the patientsCB is null on Line 1 and the application errors on Line 2 with an Object reference not set to an instance of an object exception.

Thanks,
Aditya
