title: c# Possibilities after userinput (textbox)
body: <p>I'm not sure how to ask this so I will use an example:</p>
  
  <p><strong>Words:</strong> Soccer, Swimming, Swordfighting Tennis, Baseball, Basketball, Formule1, Fishing, Cycling, ...</p>
  
  <p><strong>Control:</strong> txtSports</p>
  
  <p>When the user inputs the letter "s" in the TextBox i would like to get the possibilities that starts with an "s". (Soccer, Swimming, Swordfighting) If the user then inputs "w" (Swimming, Swordfighting) and so on.</p>
  
  <p>How can I do this? I'm doing this in c# (Windows 8 Application)</p>
