Insert this code in your button2 click and it should work :

string s = textBox1.Text.ToString();
        string[] values = s.Split(',');
        for (int i = 0; i < values.Length; i++)
        {
            values[i] = values[i].Trim();
        }

        for (int i = 0; i < checkedListBox1.Items.Count; i++)
        {
            checkedListBox1.SetItemChecked(i, false);//First uncheck the old value!
                                                     //
            for (int x = 0; x < values.Length; x++)
            {
                if (checkedListBox1.Items[i].ToString() == values[x].ToString())
                {
                    //Check only if they match! 
                    checkedListBox1.SetItemChecked(i, true);
                }
            }
        }
