title: How to add current time in a datetime control if the time is not written
body: <p>I have a <code>GridView</code> and <code>SqlDataSource</code>,</p>
  
  <p>I have a column type: <code>DateTime</code>. If I type only the date in the <code>TextBox</code>, then the time will be <code>00:00:00</code>. Is there any way of auto adding the current time if is not specified?</p>
  
  <p>Thanks</p>
