How to read a string from an ObservableCollection with given parameters?

Question

SQL

There is an ObservableCollection (with fields id, name, date) that works with combobox1 in which only name is displayed.
When changing the value on click in combobox1, you need to get id and date from ObservableCollection, how to do this?

Answer 1

In combobox1.SelectedItem you will have a selected object of type CreditsList.
In the simplest case:

public void CreditsList_SelectionChanged(object sender, SelectionChangedEventArgs args)
        {
            if(combobox1.SelectedItem != null)
                MessageBox.Show((combobox1.SelectedItem as CreditsList).credit_id);
        }
