    Hello Shahab,

    Thank you for writing.

    The information you have provided is not enough for me to be able to help you accurately. In order to avoid me guessing what you are trying to do and what your setup is, I would kindly ask you to send me a more detailed explanation of your setup and desired goals. This will save both me and you time which would otherwise be lost in communication back and forth. Things like, where do you store your appointments data, what is the format of the stored data, what operations you want to perform on the appointments inside RadScheduler and anything else you think might be relevant to the case.

    Looking forward to your reply.

    Regards,

    Hello Shahab,

    Thank you for writing back.

    I still do not have enough information to help you adequately. I would kindly ask you to send me your project so I can get a clear idea as to what you are trying to achieve what your approach is and then I will be able to accurately help you address any problems you have in the whole scenario.

    Looking forward to your reply.

    I need a complete example to work with SQL Server Database. I want to store appointment information in SQL server Tables. Existed example in online documentation did not work! I'd tested them.

    For examples:
    1. I do not know at least Id is in GUID or Int type. in some example it is in GUID type and in another it is in Int format!!!!??
    2. When I used business object how should I define Insert to database?

    Hi Shahab,

    Thank you for writing back.

    You can find a full working example of binding RadScheduler to Business Objects in our demo application. You should navigate to RadScheduler >> Data Binding. 

    I hope this will be useful. Should you have further questions, I would be glad to help.

    Dear Ivan
    As I mentioned before I check demo and forums about this. I implemented sample step by step but it did not work. In Bussiness Object demo We can not insert, update and delete from database. I do not know how can I use defined Insert, update and delete method from Bussiness Object in scheduler

    Dear Ivan
    At least I could work by business object:

    But now when I want to open CustomEdiftFormDialog as was mentioned in your samples I got this error:
    "Entry point was not found."

    I create appointment Table as attached image. I define ID(int) and UniqueID(UniqueIdentifier) because Scheduler has uniqueID columns.
    I defined business class to do Insert,Update, Delete and select from Database.
    my CustomEditForm is like your sample but Scheduler.cs is like this:

    Hi Shahab,

    Thank you for writing back.

    This exception is usually thrown when there is no Main method in a project. Since this is happening when you try to load other assemblies (probably when you click the button) I would kindly ask you to check all assemblies you are referencing. You should check whether they are all the same version and that they are the appropriate version for your project's target framework. Our controls come in two versions. The first is build targeting .NET Framework 2.0 and the second is build targeting .NET Framework 4.0. You should ensure you are referencing the appropriate assemblies for your project's target framework. Also you must reference assemblies of the same .NET version. To differentiate the two versions you can check the last two digits. They are either 20 or 40 e.g. 2013.2.612.20 or 2013.2.612.40

    I hope this will help. Do not hesitate to write back with further questions.

    Dear Ivan
    I used vesrsion 4.0(). I inheritance AppointmentBOL from Appointment. But I got error:
    Error   6   The type or namespace name 'Telerik' could not be found (are you missing a using directive or an assembly reference?)   D:\Company\Delta System\TFS\Windows\Clinic\BusinessObjectLayer\Scheduler\Patient\AppointmentBOL.cs  2   7   BusinessObjectLayer
    But when i changed it to 2.0. it is ok!
    It is very bad there is no complete sample to work with business object. your sample just select appointment.

    Hello Shahab,

    Thank you for your reply.

    You can determine whether the dialog was open for adding or editing by checking the Appointment property of the dialog that is about to be opened. It will be equal to null if the dialog is about to be opened for adding, otherwise it will be an appointment instance holding the appointment that will be edited.
    private void radScheduler1_AppointmentEditDialogShowing(object sender, AppointmentEditDialogShowingEventArgs e)
    {
        bool add = ((EditAppointmentDialog)e.AppointmentEditDialog).Appointment == null;
    }

    You are allowed to attach only images to a forum post. If you have prepared a full example you can submit it as a CodeLibrary which will allow other members of the community to benefit from your effort and knowledge.

    I hope this will help. Should you need further assistance, I would be glad to provide it.

    FormMode _FormMode = ((EditAppointmentDialog)e.AppointmentEditDialog).Appointment == null ? FormMode.Insert:FormMode.Update;               
                if (this.appointmentDialog == null)               
                    this.appointmentDialog = new CustomAppointmentEditForm();
                ((CustomAppointmentEditForm)this.appointmentDialog)._FormMode = _FormMode;
                e.AppointmentEditDialog = this.appointmentDialog;
    I implemented above code but it does not ok. When i have an appoinment for edit and after that want to insert new appointment it does not work.
    Is there another way to get Insert/Update mode  in CustomAppointmentEditForm.

    Hi Shahab,

    Thank you for writing.

    Indeed, this method does not provide valid identification on whether the dialog is opened for editing or adding. Here is another way to get indication on the purpose for which the dialog is opened:
    private void radScheduler1_AppointmentEditDialogShowing(object sender, AppointmentEditDialogShowingEventArgs e)
    {
        bool add = !this.radScheduler1.Appointments.Contains(e.Appointment);
    }

    I hope this will be useful. If your need further assistance, I would be glad to provide it.
