title: Enter Key Issue In ComboBox with AutoCompleteMode set to Append
body: <p>Pressing <kbd>Enter</kbd> key clears text of <code>ComboBox</code> when drop down is open in a <code>ComboBox</code> with <code>AutoCompleteMode</code> set to <code>Append</code>. </p>
  
  <p>We know in widows forms when the <code>AutocompleteMode</code> property in the <code>ComboBox</code> is set to <code>Append</code> then we get the values before we type the complete text of an item.</p>
  
  <p>Problem is here:</p>
  
  <ul>
  <li>I click the dropdown button and open the drop down</li>
  <li>I try to enter some characters, I get the values as expected and it completes the text.</li>
  <li>But when I press <kbd>Enter</kbd> it deletes the text of combo box.</li>
  </ul>
  
  <p>How can I have <code>Append</code> option and also make pressing <kbd>Enter</kbd> when the Dropdown is open, keep entered text and don't remove it.</p>
  
  <hr>
  
  <p>I tried the None option in the "Auto complete Mode" property it is working fine but there is no append of data....</p>
  
  <p>I dont need the suggest and suggest append options in the "Auto complete Mode" property since it opens another dropdown window....</p>
  
  <p>I need to type data while the data in the dropdown box is listed and when i get the append values just by clicking enter button it should work(without getting deleted)...</p>
  
  <p>Is this possible?</p>
  
  <p>Thanks</p>
