The Rad Editor control removes unformatted spaces between differently-formatted words when the user presses Enter key for the first time in IE

Steps to reproduce:
    1. Go to and clear all the pre-existing text.
    2. In the empty editing area, type two words separated by a space.
    3. Select the first word but not the space after it, and apply either italics, boldness, or underlining.
    4. Select the second word but not the space before it, and apply a different one of those formatting options.
    5. Position the cursor at the end of the line, and press Enter

Result: The space between the words will vanish. Firefox users will see underlining indicating that the browser considers the new, merged word to be misspelled.

Subsequent showing of an Paste HTML dialogs updates the title with some delay. 

A possible workaround is using the code from this example:

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

<script type="text/javascript">
    function OnClientCommandExecuted(editor, args) {
        var command = args.get_commandName();
        var dialogContainer = editor.get_dialogOpener()._dialogContainers;
        var dialogName = "";

        switch (command) {
            case "PasteFromWord":
            case "PasteFromWordNoFontsNoSizes":
            case "PasteAsHtml":
                dialogName = "CleanPasteHtmlContent";


    function updateTitle(sender, args) {
        var clientParameters = sender.ClientParameters;

        if (clientParameters && clientParameters.dialogTitle)

If you try to re-format a paragraph with a link inside to a heading, the final result will be multiple headings split by the link.

In Firefox, 38.0.1, some text inputs cannot be typed into. They can be focused and the cursor appears to be in the input, but you cannot type.

Entering two consecutive spaces in the middle of a paragraph causes the cursor to jump to the end of the paragraph.

The issue is reproducible with version 2015.1.401 (and not reproducible with Q3 2014)

Steps to reproduce:
1. Open the following url in IE11, setting the compatibility mode to IE8 (or in real IE8)
2. Type in a short sentence into the Editor
3. Place the cursor in the middle sentence and hit the space bar (or other char inserting button)  twice

Result: The cursor will jumps to the end of the sentence.

If the content contains html, head and body tags (Full HTML editing), and switching to Design mode causes a slightly slower rendering.

If the same HTML is used directly in the, the design mode renders as expected.

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.

Issue: The value of the href property of a link is changed while modifying the content of the link.


This is a IE's feature and can be prevented by executing "AutoUrlDetect" browser command

<telerik:RadEditor runat="server" ID="RadEditor1" OnClientLoad="OnClientLoad">
<script type="text/javascript">
    function OnClientLoad(editor, args) {
        editor.executeBrowserCommand("AutoUrlDetect", false, false);
