Ok so this question has most probably asked ad nauseum and I have searched for a solution for far too long now.

please can someone point me to an article or some code examples of how to do the following.

I have a WPF page with a datagrid (it has two manually created columns) on it. I have a ViewModel which gets my data from a table in my database and populates the datagrid (through an ObservableCollection).

all i want to do is to edit\add\delete items on the datagrid and submit the changes back to the database. my observable collection does edit\add\delete items, but how the heck do I get notified of these changes?

thanks in advance.

If you want to get notified about the ObservableCollection changes, you can register to the CollectionChanged event of it.

please could you show me how I would go about to do this?

would it be something like: MyCollection.CollectionChanged += OnCollectionChangedMethod

Yes. You have to create a method like the following: void OnCollectionChangedMethod(object sender, System.Collections.Specialized.NotifyCollectionChangedEventArgs e) { // ... } and, register to the CollectionChanged event like the following: MyCollection.CollectionChanged += OnCollectionChangedMethod;
