Hil,
I'm using Telerik.Web.UI, Version=2008.2.826.35, .NET 3.5 1, component radmenu. I got weird error reproducing
on production after few hours of running (I wasn't able to reproduce it on dev environment).

Inherit from Appointment and use AdvancedEditForm

Hello,

I try to implement a custom RadScheduler within my webapplication. The problem is I don't want to use direkt DB Binding or Objectbinding.
My own appointment objects look like this. And there is the Problem. Each of myAppointments has a List<int> AttachedFiles which I need to populate to the edit form.

    
            public class myAppointment 
        
                { 
        
                    private object m_id; 
        
                    public object ID 
        
                    { 
        
                        get { return m_id; } 
        
                        set { m_id = value; } 
        
                    } 
        
                    ... 
        
                    private DateTime m_start; 
        
                    public DateTime StartsOn 
        
                    { 
        
                        get { return m_start; } 
        
                        set { m_start = value; } 
        
                    } 
        
                    ... 
        
                    private myAppointmentFilter m_type = myAppointmentFilter.none; 
        
                    public myAppointmentFilter Type 
        
                    { 
        
                        get { return m_type; } 
        
                        set { m_type = value; } 
        
                    } 
        
                    ... 
        
                    private List<int> m_attachedFiles = null; 
        
                    public List<int> AttachedFiles 
        
                    { 
        
                        get { return m_attachedFiles; } 
        
                        set { m_attachedFiles = value; } 
        
                    } 
        
                }

Therefore I have some "DB Wrapper Classes" which load / save / delete my appointments.
This classes return a List of my own DB Appointments. This Method only loads appointments of type p_appFilter and between start and end.

    
            public enum myAppointmentFilter {none, globalFollowUps, personalFollowUps, freeAppointments }

            public class DBWrapper

            {

                public List<myAppointment> LoadAppointments(int p_userID, myAppointmentFilter p_appFilter, DateTime p_start, DateTime p_end)

                    {

                        List<myAppointment> appointments = new List<myAppointment>();

                        switch (p_appFilter)

                        {

                            case myAppointmentFilter.freeAppointments:

                                appointments.AddRange(LoadFreeAppointments(p_userID, p_start,p_end));

                                break;

                            case myAppointmentFilter.personalFollowUps:

                                appointments.AddRange(LoadFollowUps(p_start, p_end, true, p_userID));

                                break;

                            case myAppointmentFilter.globalFollowUps:

                                appointments.AddRange(LoadFollowUps(p_start, p_end, false, -1));

                                break;

                        }

                        return appointments;

                    }

                    private List<myAppointment> LoadFreeAppointments(int p_userID, DateTime p_start, DateTime p_end)

                    {...}

                    private List<myAppointment> LoadFollowUps(DateTime p_start, DateTime p_end, bool p_personal, int p_userID)

                    {...}

            }

after that I create "GUI Objects" out of my DB Appointments.
These "ExtAppointment" inherit from Telerik.Web.UI.Appoinment and add some additonal Properties. e.g. a string name, but also a List<int> fileIds.

This Inherited ExtAppointmenst will be added by the following code:

    
            public partial class scheduler : System.Web.UI.Page

                {

                    protected void Page_Load(object sender, EventArgs e)

                    {            

                        m_currentAppointments = new List<myAppointment>();

                            //Nur Appointments der ausgewählten Filter laden

                            foreach (int key in m_filterIDs.Keys)

                            {

                                CheckBox cb = PanelBar.Items[0].Items[0].FindControl(m_filterIDs[key]) as CheckBox;

                                if (cb.Checked)

                                {

                                    switch (m_filterIDs[key])

                                    {

                                        case "cbFollowUps":

                                            m_currentAppointments.AddRange(m_schedulerDBDataProvider.LoadAppointments(1, myAppointmentFilter.globalFollowUps, DateTime.Today.AddDays(-3), DateTime.Today.AddDays(3)));

                                            break;

                                        case "cbPersonalFollowUps":

                                            m_currentAppointments.AddRange(m_schedulerDBDataProvider.LoadAppointments(1, myAppointmentFilter.personalFollowUps, DateTime.Today.AddDays(-3), DateTime.Today.AddDays(3)));

                                            break;

                                        case "cbFreeAppointments":

                                            m_currentAppointments.AddRange(m_schedulerDBDataProvider.LoadAppointments(1, myAppointmentFilter.freeAppointments, DateTime.Today.AddDays(-3), DateTime.Today.AddDays(3)));

                                            break;

                                    }

                                }

                            }

                            CreateAppointments();

                        }

                        ...

                    private void CreateAppointments()

                    {

                        int id = 0;

                        foreach (myAppointment app in m_currentAppointments)

                        {

                            //ExtAppointment inherits of Telerik.Web.UI.Appointment

                            ExtAppointment telerikApp = new ExtAppointment();

                            telerikApp.ID = id;

                            telerikApp.DBID = app.DBID;

                            telerikApp.Title = app.Title;

                            telerikApp.Start = app.StartsOn.ToUniversalTime();

                            telerikApp.End = app.EndsOn.ToUniversalTime();

                            telerikApp.Description = app.Description;

                            telerikApp.UserID = app.UserID;

                            telerikApp.Type = app.Type;

                            switch (app.Type)

                            {

                                case myAppointmentFilter.globalFollowUps:

                                    telerikApp.CssClass = "rsCategoryRed";

                                    telerikApp.AllowDelete = false;

                                    break;

                                case myAppointmentFilter.personalFollowUps:

                                    telerikApp.CssClass = "rsCategoryOrange";

                                    telerikApp.AllowDelete = false;

                                    break;

                                case myAppointmentFilter.freeAppointments:

                                    telerikApp.CssClass = "rsCategoryGreen";

                                    break;

                            }

                            RadScheduler1.InsertAppointment(telerikApp);

                            id++;

                        }

                    }    

                }

So far so good, that works fine. But as soon as it comes to Load the AdvancedEditForm I get into trouble receiving my ExtAppointment. There is no problem for the base class properties. These are all loaded correctly. My problem is that my added properties do not have a value asigned.
I tried to receive the appointment like you did in some examples: (but added a cast)

    
            protected ExtAppointment Appointment  
        
            { 
        
            get 
        
            { 
        
                SchedulerFormContainer container = SchedulerFormContainer)BindingContainer; 
        
                return container.Appointment as ExtAppointment; 
        
            } 
        
            }

So finally my question comes donw to one point. How do I populate this List<int> to my advancedEditForm?
I was looking at Resources, but I guess this is not the correct way as each appointment has it's own different List. That's why I tried to inherit of Telerik.Web.UI.Appointment in order to extend the properties and manipulate them within the editform.

many thanks in advance!

grouping by just the date of a date/time value

Hello

Is is possible to set up the grid grouping expressions so that they group the rows in a grid based on just the date (and not the time) of a column of type Date?

I presume one option will be to solve the problem at the actual data source by creating a view which returned an extra column containing only the date part of the date/time data. I could then group on this field.

Is there any way I can achieve this with the grid itself?

thanks
