You can use the event’s ItemCheckEventArgs:

private void checkedListBox1_ItemCheck(object sender, ItemCheckEventArgs e)
    {
        //Note: MessageBox is for demo use only 
        MessageBox.Show("Selected Index: " + e.Index.ToString());
        MessageBox.Show("Current Value: " + e.CurrentValue.ToString());
        MessageBox.Show("New Value: " + e.NewValue.ToString());
        //Getting the item would be:
        string currentItem = (string)this.checkedListBox1.Items[e.Index];
        MessageBox.Show("Current Item: " + currentItem);
    }
