c# - 在绑定(bind)到数据源的组合框上设置 SelectedItem

Question

List<Customer> _customers = getCustomers().ToList();
BindingSource bsCustomers = new BindingSource();
bsCustomers.DataSource = _customers;
comboBox.DataSource = bsCustomers.DataSource;
comboBox.DisplayMember = "name";
comboBox.ValueMember = "id";

现在如何将组合框的项目设置为列表中第一个以外的项目？尝试过comboBox.SelectedItem = someCustomer;...还有很多其他的东西，但到目前为止还没有运气...

Answer 1

你应该这样做

comboBox.SelectedValue = "valueToSelect";

或

comboBox.SelectedIndex = n;

或

comboBox.Items[n].Selected = true;
