How to properly bind data to ComboBox?

Question

C++ / C#

List<Scenario> scenarios = new List<Scenario>();
List<Map> maps = new List<Map>();

Scenario scenario = new Scenario();
Scenario scenario1 = new Scenario();
Map map = new Map();
Map map1 = new Map();

scenario.ScenarioID = 1;
scenario1.ScenarioID = 2;
map.Name = "Russia";
map1.Name = "USA";

scenario.Map = map;
scenario1.Map = map1;

maps.Add(map);
maps.Add(map1);
scenarios.Add(scenario);
scenarios.Add(scenario1);

BindingSource source = new BindingSource();
BindingSource source1 = new BindingSource();

source.DataSource = scenarios;
source1.DataSource = maps;

comboBox1.DataSource = source;
comboBox1.DisplayMember = "ScenarioID";

comboBox2.DataSource = source1;
comboBox2.DisplayMember = "Name";

I want the first box to display a list of scenarios, and the second box to have the full list of cards, but the card that is linked to the scenario is selected. How to tie it correctly?

Answer 1

for the place of List try ObservableCollection
