Step1:

class Employee

    {

        public string ID{ get; set; }

        public string Name{ get; set; }

    }

Step2: Place a checkedListBox on Form.

Step3:

public void bind()

        {

            List<Employee> lis = new List<Employee>();

            for (int i = 0; i < 10; i++)

            {

                Employee obj = new Employee();

                obj.ID = i.ToString();

                obj.Name = "Name:" + i;

                lis.Add(obj);

            }

            checkedListBox1.DataSource = lis.ToList<Employee>();

            checkedListBox1.DisplayMember = "Name";

            checkedListBox1.ValueMember = "ID";

        }

Above method call in Form_Load.

Find the Item checked or not.

checkedListBox1.SetItemChecked(5, true);

Find the checkedList Items:

  foreach (var item in checkedListBox1.CheckedItems)

            {

                var Emp = (Employee)item;

                MessageBox.Show(Emp.ID + ": " + Emp.Name);

            }
