The parent function needs the virtual keyword  and the child function needs the override keyword in front of the function definition

Your class has a base class  and this base class also has a property  which is not virtual or abstract  called Events which is being overridden by your class  If you intend to override it put the  new  keyword after the public modifier  E G   public new EventsDataTable Events            If you don t wish to override it change your properties  name to something else

wdavo is correct  The same is also true for functions   If you override a base function  like Update  then in your subclass you need   new void Update         do stufff     Without the new at the start of the function decleration you will get the warning flag

In the code below  Class A implements the interface IShow and implements its method ShowData  Class B inherits Class A  In order to use ShowData method in Class B  we have to use keyword new in the ShowData method in order to hide the base class Class A method and use override keyword in order to extend the method    interface IShow       protected void ShowData       class A   IShow       protected void ShowData                 Console WriteLine  This is Class A             class B   A       protected new void ShowData                 Console WriteLine  This is Class B
