title: Refresh TextBox text?
body: <p>I will explain the situation:</p>
  
  <ol>
  <li><p>My form have a listview, a textbox, and a label.</p></li>
  <li><p>The Textbox is to write a directory path to add that directory to the listview.</p></li>
  <li><p>With the event OnTextchanged of the textbox I check if the listview contains the textbox text before adding it, if yes then the label says "<strong>Directory is already in the listview</strong>" if not then the label says otherwise.</p></li>
  <li><p>Now, after adding the directory path from the textbox to the listview, like I don't modified the textbox text after adding the text to the listview then the OnTextChanged event of the textbox is not processed so the label is still saying that the directory <strong>IS NOT</strong> inside the listview (because the OnTextchanged event is not processed).</p></li>
  </ol>
  
  <p>Then to solve this little issue I refresh the text of the textbox after adding the text to the listviewx, I did it with a little snippet I've made for this:</p>
  
  <pre><code>Private Sub Refresh_Textbox_Text(ByVal TextBox As TextBox)
      Dim TempText As String = TextBox.Text
      TextBox.Clear()
      TextBox.Text = TempText
  End Sub
  </code></pre>
  
  <p>But I think that's a noob way to do it, I wonder if exists a native method to do refresh in the way I need the text of a textbox like seen in that snippet, I've tried with some methods as "refresh", "invalidate", etc... but none does the same.</p>
