    I have BindingList<> which is filled from the database. When I edit/delete the record from the grid which shows this list in UI and commit the transaction, it has no effect in database, but BindingList contains all changes. After deleting record I have no object which I can remove from the scope.
    Should I realise event handlers like RecordsDeleting / CellUpdated in my datagrid component for manually removing objects from scope or there is other ways to get the same functionality?

    Hi 1,

    You should handle the RadGridView.DataBindings.CollectionChanged event. There you should just commit the transaction so you can persist the changes to the database:

    protected void DataBindings_CollectionChanged(object sender, CollectionChangeEventArgs e)
        if (scope.Transaction.IsActive)

    Hope that helps.

    Best wishes,
