CanDelete?

Hi,

I'm coding some lists again, and I'm coming across this issue again. Sometimes, items in the list cannot be deleted, for whatever reason. So I'm trying to work out a good way for the UI to determine this.

In this case, an instance that is saved into the database can't be removed, but if a user addes a new row they should be able to delete it.

So whats would be the "proper" way to handle this? Add a CanDelete property to the instance? Add a CanDelete method to the list? (The list already overrides RemoveItem to prevent removing instances).

Should there be some standard way to ask if an item can be deleted?

Hi,

I will point to my answer to another similar question:

I prefer to use the methods that Rocky has already provided in Csla and add my own custom checks in overrides.
