How to change property value after open appointment dialog and make it reflect at UI

[Ahmed]

i create my custom appointment to add two more properties like 

      public string Title
        {
            get { return _title; }
            set
            {
                _title = value;
                OnPropertyChanged("Title");
            }
        }
        public string Gender
        {
            get { return _gender; }
            set
            {
                _gender = value;
                OnPropertyChanged("Gender");
            }
        }

Hi

We're in a similar situation, where the appointment dialog UI does not reflect changes in custom appointment VIewModel once the dialog is open.

Can Telerik please provide an answer to this?

Hello,

Please make sure that you're using the Storage method of the AppointmentBase class when setting/getting custom properties. The approach is described in details in the following article:

Hi

Yes we are using it. Here is an extract from our class extension of AppointmentBase

public string PatientName
        {
            get
            {
                return Storage<AppointmentViewModel>()._patientName;
            }
            set
            {
                var storage = Storage<AppointmentViewModel>();
                if (storage._patientName != value)
                {
                    storage._patientName = value;
                    OnPropertyChanged(() => _patientName);
                }
            }
        }

public bool IsHealthPromotion
        {
            get { return Storage<AppointmentViewModel>()._isHealthPromition; }
            set
            {
                var storage = Storage<AppointmentViewModel>();
                if (storage._isHealthPromition != value)
                {
                    storage._isHealthPromition = value;
                    OnPropertyChanged(() => IsHealthPromotion);
                }
            }
        }

protected override void OnPropertyChanged(string propertyName)
        {
            base.OnPropertyChanged(propertyName);

            if (propertyName == "IsHealthPromotion")
            {
                if (IsHealthPromotion)
                    PatientName = "health promotion";
                else if (PatientName != null && PatientName.ToLower().Equals("health promotion"))
                    PatientName = string.Empty;
            }
        }

When we select the checkbox for IsHealthPromotion it should set the PatientName textbox value to "health promotion"

By debugging we see that this does occur in the code, it's even saving to server correctly. However the UI will not update PatientName textbox as we're selecting the checkbox.

Hello Rav,

We've just created a new Code Library which demonstrates how you can update the appointment properties in the EditAppointmentDIalog. Please check it at the following link:
http://www.telerik.com/community/code-library/silverlight/scheduleview/how-to-create-advanced-custom-editapointmentdialog.aspx

If you have any issues with the approach, write to us again.

Hi Yana, 

OK I found the code, and yes it did reflect changes in the UI thanks. However when I saved and opened the dialog again the changes were not persisted (even though they had saved correctly back to server). I removed this part 'ElementName=DialogRoot' and it worked.
