title: How to make autocomplete on a TextBox show suggestions when empty
body: <p>I am using the AutoComplete properties on a textbox (actually a ToolStripTextBox). This is working fine except it doesn't show until I type at lease one character. How do I make it so the suggestions are shown even if the textbox is empty?</p>
  
  <pre><code>Mode = Suggest
  Source = CustomSource
  </code></pre>
  
  <p>Source set progamatically and limited to 10 items</p>
  
  <p>Alternatively if someone knows how to force the suggestions to show programatically on the OnEnter event that might be a solution</p>
