Add PropertyChanged to inheritable class

[Andrei Alfritovich Bilalov]

Hello.

My class inherits from the class KanbanViewModel.

It has the variable property "BackgroundColor". How can I hang on him "PropertyChanged"?

public class KanbanViewModel : KanbanModel
{
    private Brush _backgroundColor;
    public Brush BackgroundColor
    {
        get { return _backgroundColor; }
        set
        {
 
           ???
        }
 
    }
}

My problem - I can't use INotifyProperyChanged, because KanbanModel already implement this interface.

Hi Andrei, 

Thanks for contacting Syncfusion Support. 

We can notify the property changed for the property in the class which inherits the KanbanModel class. Please refer the below code sample to notify the property changed. 

Code sample: 

[C#] 

 

public class KanbanViewModel : KanbanModel 

{ 

       private MethodInfo _methodInfo; 

 

       private Brush _backgroundColor; 

 

       public Brush BackgroundColor 

       { 

              get { return _backgroundColor; } 

              set 

              { 

                     _backgroundColor = value; 

                     if (_methodInfo != null) 

                           _methodInfo.Invoke(this, new object[] { "BackgroundColor" }); 

              } 

       } 

               

       public KanbanViewModel() 

       { 

              //Reflected the NotifyPropertyChanged method.  

              _methodInfo = this.GetType().GetMethod("NotifyPropertyChanged", BindingFlags.NonPublic | BindingFlags.Instance); 

       } 

} 

Thanks, 

Satheesh
