Combobox dropDown selected

I have a ComboBox which also gets controlled by two buttons. But I would like to separate the execution from using the ComboBox dropdown and the buttons.

comboBox3.DropDownClosed += (b, f) =>
{
    week = Convert.ToInt16(comboBox3.Text);
    Console.WriteLine(week);
};

I tried this approach but it seems to be not updating the week when the dropdown gets closed and selecting another value.

If you want to do something when user changes the selected index of the ComboBox, you need to handle SelectionChangeCommitted event (and not SelectedIndexChanged):

The SelectionChangeCommitted event is raised only when the user changes the combo box selection, and you can create a handler for this event to provide special handling for the ComboBox when the user changes the selected item in the list.

In the other hand, SelectedIndexChanged will raise whenever the user or code changes the selected index.

So, instead of handling SelectedIndexChanged, you should write different methods to do different things, for example, handle Button1.Click and call Action1, handle Button2.Click and call Action2 and handle ComboBox.SelectionChangeCommitted to detect when user changes the selected index and call Action3.
