How to hold loop progress until an event completes?

i'm trying loop through text in textbox word in order spellcheck it. i've split contents of textbox array, , loop through each word in array , run through spellchecker. when misspelling found, have popup listbox inside display can choose correction.

issue i'm having, loops through whole array , ends showing last correction needs done.

how pause loop waits selection made , resume?

here's code loop:

  foreach(string checkedword in articlewords)
        {
            bool success = _spellchecker.checkword(checkedword);
            list<string> suggest;

            if (!success)
            {
                suggest = _spellchecker.getsuggestions(checkedword);
                spellchecklistbox.items.clear();

                foreach (string s in suggest)
                {

                   spellchecklistbox.items.add(new listboxitem() { content = s });

                }
                spellcheckerpopup.isopen = true;
                spellchecklistbox.items.add(new listboxitem() { content = "          ----------------------" });
                spellchecklistbox.items.add(new listboxitem() { content = "ignore" });
            }


        }

when spellcheckerpopup displays, have event trigger in listbox on selectionchange.

basically, need pause loop somehow, , when selectionchange event it's thing, have loop resume.

in advance!

// set value articlewords here  queue<string> articlewords;            private void dowork()  {      if (articlewords.count() > 0)      {          string checkedwork = articlewords.dequeue();          bool success = _spellchecker.checkword(checkedword);          list<string> suggest;            if (!success)          {              suggest = _spellchecker.getsuggestions(checkedword);              spellchecklistbox.items.clear();                foreach (string s in suggest)              {                  spellchecklistbox.items.add(new listboxitem() { content = s });              }                spellcheckerpopup.isopen = true;              spellchecklistbox.items.add(new listboxitem() { content = "          ----------------------" });              spellchecklistbox.items.add(new listboxitem() { content = "ignore" });          }      }  }            private void listbox1_selectionchanged(object sender, selectionchangedeventargs e)  {      dowork();  }

hope helps!
