title: set combobox text from textbox
body: <p>I have user submitted content that is loaded into c# winform in our office for processing before officially added to database. The user can submit a 'Referrer' as two text fields-first and last name. In the office I want to have a combobox will all existing referrers loaded in, then the first couple letters of the name to advance the combobox down to the area it needs to be at. I want to do something like this, taking the first two letters of the name and use that to initialize the combobox.</p>
  
  <pre><code>if (txtrefFirstName.TextLength &gt; 2)
  {
     string firstStart = "" + txtrefFirstName.Text[0] + txtrefFirstName.Text[1];
     firstStart = firstStart.ToUpper();
     ddlReferring.SelectedText.StartsWith(firstStart);
  }
  else
     ddlReferring.Text = "";
  </code></pre>
  
  <p>Any ideas or suggestions to get this to work?</p>
  
  <p>Thanks</p>
