Hi,
I have a masterdetail program. The datagrid is bound to the Rows property which is an observable collection and the detail is bound to the CurrentRow property which is a class from the entity framework.
First i was using ef4 with Code Generation Strategy Legacy ObjectContext. And i addes partial classes which implemented IDataErrorInfo. Now i made a new project with the same mvvm and with ef6.
My problems are that i can't change the Code Generation Strategy from T4 to something else (because it's disabled) and i can't create new partial classes with the name of the entity because ef already generated them. This made me think that maybe i am doing something wrong.
My questions are:
Where do i have to put validation?
How do i notify the viewmodel of changes in the model (For example when the value of a column in CurrentRow changes how can i respond to that in the view model).
I am searching for days now so i hope someone can help me with this.
