OnpropertyChanged() method is a non static.

Is there any way to use OnpropertyChanged method for static properties?

I found solution using Delegates

public static EnableDelegate DelEnable = new EnableDelegate(DelCal);

C#

public delegate void EnableDelegate();
        private void DelCal()
        {
            OnPropertyChanged("IsEnable");
        }

C#

private static Visibility isenable;
       public static Visibility IsEnable
       {
           get
           {
               return isenable;
           }
           set
           {
               if (isenable != value)
               {
                   isenable = value;                   
               }
           }
       }

//Invoking delegate when changing the value

IsEnable = Visibility.Hidden;
DelEnable();
