I have a grid using the GridClientSelectColumn and I also have a button that calls RadGrid.Rebind().
After the call to rebind, when a user tries to click on the grid row's checkbox nothing happens. here is the code (simplified).

Thanks!

Client Binding & DbSchedulerProviderBase

I was playing around with the new bits and wanted to try to use WCF Service using DbSchedulerProviderBase.
I kept getting errors on the DbSchedulerProviderBase method LoadResources when it tries to add a Resource to the appointment.
I thought I must had done something wrong so I open the Quick Start Examples in Visual Studio and altered the example http://demos.telerik.com/aspnet-ajax/scheduler/examples/wcf/defaultcs.aspx to use the MyDbSchedulerProvider instead by passing in the name of provider from web.config:

    
                private WebServiceAppointmentController Controller  
        
                {  
        
                    get 
        
                    {  
        
                        if (_controller == null)  
        
                        {  
        
                            //_controller =  
        
                            //    new WebServiceAppointmentController(  
        
                            //        new XmlSchedulerProvider(HttpContext.Current.Server.MapPath("~/App_Data/Appointments_Outlook.xml"),   
        
                            //            false));  
        
                            _controller = new WebServiceAppointmentController("ReadOnlySchedulerData");  
        
                        }  
        
                        return _controller;  
        
                    }  
        
                }

I then ran the page and got the same error on the method below on line 16:

    
                    private void LoadResources(Appointment apt)  
        
                    {  
        
                        using (DbConnection conn = OpenConnection())  
        
                        {  
        
                            DbCommand cmd = DbFactory.CreateCommand();  
        
                            cmd.Connection = conn;  
        
                            cmd.Parameters.Add(CreateParameter("@ClassID", apt.ID));  
        
                            cmd.CommandText = "SELECT [TeacherID] FROM [DbProvider_Classes] WHERE [ClassID] = @ClassID AND [TeacherID] IS NOT NULL";  
        
                            using (DbDataReader reader = cmd.ExecuteReader())  
        
                            {  
        
                                if (reader.Read())  
        
                                {  
        
                                    Resource teacher = apt.Owner.Resources.GetResource("Teacher", reader["TeacherID"]);  
        
                                    apt.Resources.Add(teacher);  
        
                                }  
        
                            }  
        
                            cmd.Parameters.Clear();  
        
                            cmd.Parameters.Add(CreateParameter("@ClassID", apt.ID));  
        
                            cmd.CommandText = "SELECT [StudentID] FROM [DbProvider_ClassStudents] WHERE [ClassID] = @ClassID";  
        
                            using (DbDataReader reader = cmd.ExecuteReader())  
        
                            {  
        
                                while (reader.Read())  
        
                                {  
        
                                    Resource student = apt.Owner.Resources.GetResource("Student", reader["StudentID"]);  
        
                                    apt.Resources.Add(student);  
        
                                }  
        
                            }  
        
                        }  
        
                    }

The method GetResource returns null.

Can you check it out and let us know how to implement client binding from a database.

BTW I added a check for null and it works but of course there is no resources so it is specifically relating to how to load resources.
We can load resources from XML so I guess we just need to change the implementation of DbSchedulerProviderBase unless I have really missed somthing here.

Overlapping line graphs

Hi,

I have a few line graphs (chartseries) in a single chart and they overlap each other when the values are the same.
Is there any way to position one line graph slightly below another so that both can be seen even if the values are the same.
Thanks for any advice.

Regards,

Advanced drag and drop questions

I have a RadScheduler with a RadGrid, utilizing the drag and drop from the grid to the scheduler. All works great! (Thanks for the good online example)

I am also utilizing resources in the scheduler. Is there a way to map the dropped item to the proper resource it was dropped into? Currently I am mapping the name fields and the time slots are being set by the HandleSchedulerDrop method. I want to do all the above and have it know which resource I dropped it into. Is this possible?

Secondarily I have other fields associated with the scheduler item that are not in the grid item. So I want the user to enter those values when they drop the grid item into the scheduler. To do this, I envision the advanced edit form opening on drop. I have the StartEditingInAdvancedForm set to true, so I assume all I need to do is put the scheduler in edit mode for that item. Is this possible?

Thanks.
