title: ASPxTextbox - masking, prompt always at last or first character
body: <p>I have an aspxtextbox e.g </p>
  
  <pre><code>  &lt;dxe:ASPxTextBox ID="txtZip" runat="server" Width="150"&gt;
                              &lt;MaskSettings Mask="00000" ErrorText="Please input missing symbols" /&gt;
                              &lt;ValidationSettings ErrorDisplayMode="ImageWithTooltip" /&gt;
                          &lt;/dxe:ASPxTextBox&gt;
  </code></pre>
  
  <p>How can I modify it so that when the user goes to the textbox, it will always position the cursor at index 0, or the last entered character?</p>
  
  <p>Thanks,</p>
