When there are words highlighted as wrong and triggering the Finish Spellchecking without correcting any words, subsequent editing of words inside the sentence causes random cursor replacement. 


<telerik:RadEditor ID="RadEditor1" runat="server" OnClientLoad="OnClientLoad">
    <Content>Whether you need a mere Textbox with Google-like spellchecker, or a Word-like content authoring environment, the result is the same: clean <strong>XHTML</strong></Content>

    function OnClientLoad(sender, args) {

    function spellCheckLoaded(sender) {
        var editor = sender;
        var spell = editor.get_ajaxSpellCheck();

        spell.add_spellCheckEnd(function (sender, args) {

When a parent control is disabled by setting Enabled to false, all children controls should inherit the behavior and act as disabled. RadEditor does not follow this logic and stays enabled.

Browser : IE11
Telerik version : 2013.3.1114.40 - Q3 2013 release

Steps to reproduce the issue :
1 . Copy ordered list from MS WORD 2010
2.  Paste it in RadEditor
3.  View html markup in radeditor

Each text within LI tag is wrapped by P tag and this issue occurs only in IE11 browser.

Ideally ,p tags should be stripped off.

Looking forward to your response.

Thanks in advance,

When two RadEditors with different TrackChanges mode are defined on the page, a JavaScript error is thrown when inserting a list. The issue is reproducible only when the firstly declared RadEditor has EnabledTrackChanges set to false (the default value), while the second one has EnabledTrackChanges set to false.

Temporary workarounds:

Variant 1: Declare the not tracked RadEditors after the tracked ones, so there scripts will be loaded properly.

Variant2: Set the EnabledTrackChanges of all RadEditors on the page to true.

Steps to reproduce
1. Run the following code:

    <telerik:RadEditor ID="RadEditor1" runat="server">
        <telerik:RadEditor ID="HiddenRadEditor" runat="server" EnableTrackChanges="true">

2. Write something and press Enter

3. Click on the "Unordered List" tool

Result: A JavaScript error is thrown

When paragraphs are pasted from e.g., MS Word, multiple BR tags are pasted instead of the corresponding amount needed.

The flowing custom handler shows how this can be handled as per to the specific requirements:

<telerik:RadEditor runat="server" ID="RadEditor1"

<script type="text/javascript">
    function OnClientPasteHtml(editor, args) {
        var commandName = args.get_commandName();
        var contentToPaste = args.get_value();

        if (commandName === "Paste") {
            contentToPaste = contentToPaste.replace(/(<br\/>)+/gi, "<br/>");

A div element is considered as a new line and can be transformed to a list item, although the reverse logic does not work. When NewLineMode is set to Div, the list item is transformed to paragraph instead div element.

The RadEditor's Media Manager dialog uses pasteHtml functionality to insert Object elements in the contentArea. The pasteHtml functionality do not position the cursor correctly for this case (pasted content ends with a object).

The issue can be workarounded by appending a character after the object. Then using a content filter the additional characters will be removed.

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

<script type="text/javascript">
	function OnClientPasteHtml(editor, args) {
		if ($telerik.isChrome && args.get_commandName() == "MediaManager") {
			args.set_value(args.get_value() + String.fromCharCode(8203));

	function OnClientLoad(editor, args) {
		if ($telerik.isChrome) {
			editor.get_filtersManager().add(new MyFilter());

	MyFilter = function() {
		this.set_name("RadEditor filter");
		this.set_description("RadEditor filter description");
	MyFilter.prototype =
		getHtmlContent: function(content) {
			return content.replace(/(object>)[\u200b]/gm, "$1"); // or content.replace(/[\u200b]/gm, "")
		getDesignContent: function(content) {
			return content;
	MyFilter.registerClass('MyFilter', Telerik.Web.UI.Editor.Filter);

Create a page as below and assign a limited toolset to each editor in the code behind:

 <telerik:RadEditor  ID="RadEditor1" Skin="Default"  ContentAreaMode="Div"   runat="server"      Width="265px" Height="120px"  ToolsWidth="265px">
       <Content><p>A Word</p> </Content>
 <telerik:RadEditor  ID="RadEditor2" Skin="Default"  ContentAreaMode="Div"   runat="server"     Width="265px" Height="120px"  ToolsWidth="265px">
       <Content><p>A Word</p> </Content>
[Continue with this until ...]

 <telerik:RadEditor  ID="RadEditor10" Skin="Default"  ContentAreaMode="Div"   runat="server"     Width="265px" Height="120px"  ToolsWidth="265px">
       <Content><p>A Word</p> </Content>
Now display this page and right click for the top editor's Context Sensitive popup menu. Now scroll down to the bottom menu and right click for that menu's context sensitive menu. My experience is that this will erroneously produce the popup at the top of the browser. This is the most extreme example of a general behaviour where the vertical placement of popups is typically off the mark when working with multiple editors and ContentAreaMode="Div". Get rid of the ContentAreaMode="Div" and the problem disappears.

When a document is deleted from the DocumentManager, its selection remains and it could be inserted into the Editor.

The problem is reproducible when the selected element has a CSS property applied that enables the hasLayout feature of the element under IE.

When an anchor hasLayout we cannot properly select it. The hyperlink manager shows the text, but modifying it is not carried to the actual markup. 

CSS properties that trigger hasLayout in IE:

CSS property	Value
display	inline-block
height	any value
float	left or right
position	absolute
width	any value
-ms-writing-mode	tb-rl
zoom	any value
