  Hi,
  
  Baed on http://demos.telerik.com/aspnet-ajax/editor/examples/validators/defaultcs.aspx, how can I hide the required filed validator of RadEditor immediately after filling the content and clicking out of it, without clicking on the "Submit" button? exactly like the required filed validators of other controls in the form.
  
  Regards,
  Bader

  Hello Bader,
  
  You can attach to the blur event of the content area of RadEditor and execute your own validation code. You can see how to attach to the editor's content area events in this article: attachEventHandler.
  
  For example:
  

  <telerik:RadEditor ID="RadEditor1" runat="server" OnClientLoad="checkLength"></telerik:RadEditor>

  <script type="text/javascript">

      var limitNum = 50;

   

      function checkLength(editor, args) {

           

          var element = document.all ? editor.get_document().body : editor.get_document();

          $telerik.addExternalHandler(element, "blur", function (e) {

              if (editor.get_text().length > limitNum) {

                  alert("The text length should not exceed " + limitNum + " symbols.");

                  editor.setFocus();

              }

          });

      } 

  </script>

  Hi, I use too the RadEditor control. In my case this is my control code
  
  <telerik:RadEditor ID="RadEditorSumario" runat="server" Skin="Office2007" SpellCheckSettings-DictionaryLanguage="es-ES"
  Width="400px" ContentFilters="None" NewLineBr="true">
  <Tools>
  <telerik:EditorToolGroup>
  <telerik:EditorTool Name="Bold" />
  <telerik:EditorTool Name="Italic" />
  <telerik:EditorTool Name="Underline" />
  <telerik:EditorTool Name="LinkManager" />
  <telerik:EditorTool Name="StrikeThrough" />
  <telerik:EditorTool Name="Undo" />
  <telerik:EditorTool Name="Redo" />
  <telerik:EditorTool Name="InsertOrderedList" />
  <telerik:EditorTool Name="InsertUnorderedList" />
  <telerik:EditorTool Name="JustifyLeft" />
  <telerik:EditorTool Name="JustifyCenter" />
  <telerik:EditorTool Name="JustifyRight" />
  <telerik:EditorTool Name="JustifyFull" />
  <telerik:EditorTool Name="PastePlainText" />
  <telerik:EditorTool Name="PasteAsHtml" />
  <telerik:EditorTool Name="AjaxSpellCheck" />
  </telerik:EditorToolGroup>
  </Tools>
  </telerik:RadEditor>
  <asp:CustomValidator ID="cvSumario2" runat="server" ControlToValidate="RadEditorSumario"
  Text="(*)" ErrorMessage="Debe ingresar el sumario o descripción del pillate la foto"
  ForeColor="Red" ClientValidationFunction="ValidarCampoObligatorioRegEx" />
  
  
  I resolved the problem with this javascript
  
  function ValidarCampoObligatorioRegEx(source, args) {
  var pattern = "^(<br>|<br/>|<BR>|<BR/>|&nbsp;|\\s)*$";
  var regex = new RegExp(pattern);
  var text = args.Value;
  var doMatch = text.match(regex);
  args.IsValid = !(doMatch);
  }
