Solution 1

You should modify your code like this:

C#

 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])
           {
               //Check only if they match! 
               checkedListBox1.SetItemChecked(i, true); 
           }
  }
}

You answered only to my first question. So you have the label with some text and the world from your label text are the items of your checkboxlist, right?
And big question is what do you want to happen when you select one ore more items in your checkboxlist?
