Hi Alejandroha,

Thank you for report.
Javascript support for validators was not implemented for several reasons. One of the them, that visible content in design view may not represent actual html, and it is not possible to guess if application will consider empty object as a valid content. For example, default-empty-content in Firefox appears as "<br>". After cut/remove or change color/font, etc. the html-content may appear as "<font some-attributes></font>" or "<span some-attributes></span>". Also html-content may have invisible objects like <script>, <style>, etc.

Support for validators on client was reviewed and validation for most actions will be implemented.
For now application may implement that by something like below.
Underlined are key-statements and the rest is optional.

<script type="text/javascript">
function editorChange(oEditor)
{
 // perform validation with (10ms) delay,
 // because actual change may happen not at processed event, but slightly later
 setTimeout(function ()
 {
  var elem = oEditor._elem0;
  //or
  //var elem = document.getElementById(oEditor.ID);
  // short-cut for element which holds validators created by server
  var validator = oEditor._validator;
  if(!validator)
  {
   // try to find element which holds validators created by server
   var inputs = elem.getElementsByTagName('INPUT');
   // ensure that ValidatorOnChange function is available
   var i = window.ValidatorOnChange ? inputs.length : 0;
   while(i-- > 0 && !validator)
    if(inputs[i].Validators)
     validator = inputs[i];
   // create a short-cut for element which holds validators
   oEditor._validator = validator = validator || 'none';
  }
  if(validator == 'none')
   return;
  // get current text in editor
  var text = oEditor.getText().toLowerCase();
  // optional: remove empty <font> object
  if(text.indexOf('<font') == 0)
  {
   text = text.substring(text.indexOf('>') + 1);
   if(text.indexOf('</font>') == 0)
    text = text.substring(7);
  }
  // optional: remove empty <span> object
  if(text.indexOf('<span') == 0)
  {
   text = text.substring(text.indexOf('>') + 1);
   if(text.indexOf('</span>') == 0)
    text = text.substring(7);
  }
  // optional: remove empty <br>, <p> objects
  if(text == '<br>' || text == '<br/>' || text == '<br />' || text == '<p></p>' || text == '<p>&nbsp;</p>')
   text = '';
  // set property for target-element expected by server-validators
  elem.value = text;
  // trigger validation
  window.ValidatorOnChange({ srcElement: validator });
 }, 10);
}
</script>

Hi Maya,

I'm using the same version you mention. I've made a little change to the files you attached to make easier to explain the scenario I'm facing. Here is what I'm doing:

1. Leave the fields empty.

2. Click on the button so the validator message appears.

3. Start writing some text in the html editor.

4. Move to the other field.

After step 4, I would expect the validation message to disappear.

I've solved this adding some javascript, but I was expecting a way to get the same behavior that for other controls.

Thanks
