title: RequiredFieldValidator ErrorMessage does not delete itself even though TEXT does?
body: <p>This is some old code that I am not too familiar with : </p>
  
  <pre><code> RequiredFieldValidator vldRequired = new RequiredFieldValidator();
                      vldRequired.Display = ValidatorDisplay.Dynamic;
                      vldRequired.Text = "*";
                      vldRequired.ControlToValidate = "txtSetting";
                      vldRequired.ID = "vldRequired";
                      vldRequired.Enabled = true;
                      vldRequired.ErrorMessage = SettingTitle + " is required";
                      returnCell.Controls.Add(vldRequired);
  </code></pre>
  
  <p>Where, IF you tab passed a required field the * will show up next to it.  THE ErrorMessage only shows up when a Submit is clicked (that is all fine).  </p>
  
  <p>However, once you fill in the required field and tab out of the input, the "*" goes away but the ErrorMessage stays -- I cannot figure out how to make that ErrorMessage go away when the * does.</p>
  
  <p>Help?</p>
