推荐答案

Hello Hazem，

查看ComboBox的事件SelectedIndexChanged，SelectedValueChanged和属性SelectedItem.因此，当CBA进行选择更改时，您
适当地填充CBB.

填充CB B:

Hello Hazem,

look at ComboBox''s events SelectedIndexChanged, SelectedValueChanged and the property SelectedItem. So when CB A has a selection change you
populate CB B appropriately.

Populating CB B:

comboBox1.Items.Clear();
comboBox1.Items.Add(new Item("Blue", 1));
...
...

干杯
