Appointment BarColor equivalent | Infragistics Forums

Hi Diyan,

thanks to your suggestions I made it work the way I wanted. Let me point out though, in case someone else stumble in the same obstacle, that at first I was going crazy since I could not see anything but empty timeslots. After some headbanging I found the problem: since I prefer to avoid using literals in the INotifyPropertyChanged implementation I don't use:

this.RaisePropertyChanged("Description");

instead I use


  NotifyPropertyChanged(descriptionChangeArgs);
where descriptionChangeArgs is declared as follows.
  private static PropertyChangedEventArgs descriptionChangeArgs = ObservableHelper.CreateArgs<MyClass>(x => x.Description)
You must have seen many of this implementations around.

I inherit from a base class that implements the INotifyPropertyChanged as follows:
    public abstract class ViewModelBase : INotifyPropertyChanged
    {
        #region INotifyPropertyChanged
 
        public event PropertyChangedEventHandler PropertyChanged;
 
        /// <summary>
        /// Notify using pre-made PropertyChangedEventArgs
        /// </summary>
        /// <param name="args"></param>
        protected void NotifyPropertyChanged(PropertyChangedEventArgs args)
        {
            PropertyChangedEventHandler handler = PropertyChanged;
 
            String propertyName = args.PropertyName;
          
            if (handler != null)
            {
                handler(this, args);
            }
        }
 
        /// <summary>
        /// Notify using String property name
        /// </summary>
        protected void NotifyPropertyChanged(String propertyName)
        {
            PropertyChangedEventHandler handler = PropertyChanged;
 
            if (handler != null)
            {
                handler(this, new PropertyChangedEventArgs(propertyName));
            }
        }
 
        #endregion
 
    }

So my first attempt has been to directly implement INotifyPropertyChanged in MyAppointment Class and continuig to avoid the use of literals, without results.
Finally I used your class with literals and ...it worked.
Is this expected behaviour?
It's not a big issue but gave me headaches for a couple of hours.
Best Regards
