Cast Observable Collection from base Class to inherited class My real issue is how to remove the repeated code which needs to reference the GridData observable collection (But is only interested in the MessageParentBase class fields) in the base class of the ViewModel while still being able to initiate the observable collection as a ChatMessage one. I thought I could declare the field in the base viewmodel and then Declare the property in the derived ViewModel but I'm being told I cannot implicity convert from one ObservableCollection to another even though one class inherits from the other. |

Cast Observable Collection from base Class to inherited class I've tried this approach but as the GridData is declared as ObservableCollection<MessageParentBase>() it still does not display the fields from the derived class. |

Cast Observable Collection from base Class to inherited class Ah I was thinking this was the case. Is there someway I can have some reference in base class as a lot of the functionality I was hoping to move to this class is not looking for specific of the ChatMessage class and this observable collection. Otherwise I'm going to have a lot of repeated code for each viewmodel which uses a different derived class from MessageParentBase. |
