Use the demo at:
 http://demos.telerik.com/aspnet-ajax/editor/examples/overview/defaultcs.aspx  

Select html mode and clear all existing text
Enter some text and format it as bold, italic and underline 
Enter 2 new lines (breaks)  
Insert a 3x3 table using the table button in the editor 

Result: When the table is inserted the text loses its formatting. See attached file.

As Bootstrap is the industry standard for website and app grids, a very powerfull addition for RadEditor would be a Bootstrap grid builder like this one:

https://www.youtube.com/watch?v=WQZ9zcf_ZRo

How cool would that be, building your Bootstrap parts in the Editor itself. Did anyone try this? Any hints on how one could build this functionality.

Let me know if we could collaborate to get something like this.

Thanks,

Marc

If the Track Changes feature is enabled Japanese and Korean languages are not detected as modified. The added text is not highlighted.

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"
    OnClientPasteHtml="OnClientPasteHtml"
    StripFormattingOptions="AllExceptNewLines">
</telerik:RadEditor>

<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/>");

            args.set_value(contentToPaste);
        }
    }
</script>

When multiple paragraphs are set into the content and selected, the font name tool of the StyleBuilder dialog is merging all f them into one span.
This causes unexpected behavior and incorrect text manipulation. 

The contenteditable feature is not working as per the instructions from Editable and Non-Editable Areas

Reproduction

<telerik:RadEditor runat="server" ID="Casenote" EditModes="Design">
    <Content>
        <div style="border: red 1px solid;" contenteditable="false" unselectable="on">
            Non Editable AREA
            <div style="border: green 1px solid;" contenteditable="true" unselectable="off">
                <!--Content name="info" -->
                Editable REGION...
                <!--/Content -->
            </div>
            Non Editable AREA
        </div>
    </Content>
</telerik:RadEditor>

Telerik version 2011.1.614.35
I am facing following two issues with RadEditor on Chrome (version 28.0.1500.95) and Safari (version 5.1.7) -

a. Gray area is seen in the lower part of the RadEditor for Design and Preview modes. When some text is typed, the gray background vanishes for that line of text. 

b. Border of the RadEditor is not complete at the bottom left corner in the HTML mode. This behavior is seen whenever there is some text in it, be it the default text or the text of the field that is bound. 

Please refer the attachment RadEditorIssues.png 

The Paste event is added twice to the Editor's undo stack in IE. The issue is reproducible as of Q3 2013.

Steps to reproduce:
1. Open http://demos.telerik.com/aspnet-ajax/editor/examples/overview/defaultcs.aspx
2. Paste some content

Result: The Paste command is added two time in the Undo stack

Hi,

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,
Anthony

Steps to reproduce:
Run this in IE7 or another IE in IE7 mode:
<telerik:RadEditor ID="RadEditor1" runat="server" EditModes="Preview"></telerik:RadEditor>

Workaround:
<telerik:RadEditor ID="RadEditor1" runat="server" EditModes="Preview"></telerik:RadEditor>

<script type="text/javascript">
	(function ($T) {
		if ($telerik.isIE7) {
			var prototype = $T.Editor.UI.SizerLegacyIE.prototype;
			var setContentElementHeight = prototype.setContentElementHeight;
			$T.Editor.UI.SizerLegacyIE.prototype.setContentElementHeight = function () {
				setContentElementHeight.call(this);
				var editor = this.editor;
				if (editor.get_mode() != $T.EditModes.Html) {
					var iframeParent = this.getIframe().parentNode;
					if (Math.abs(iframeParent.offsetHeight - editor.get_element().offsetHeight) < 5) {
						iframeParent.style.height = "";
					}
				}
			}
		}
	})(Telerik.Web.UI);
</script>

Having the entity in a sentence, and trying to find or find and replace in this sentence, the found word seem to be incorrectly highlighted/selected. Therefore, when trying to replace, incorrect selection is replaced.

A possible fix is adding the entities inside span elements, so that additional inner text nodes are created.

The following code example implements such functionality upon opening and closing the FindAndReplace dialog 
<telerik:RadEditor ID="RadEditor1" runat="server" OnClientCommandExecuted="OnClientCommandExecuted">
    <Content>
        <p>some text.&nbsp; some text.</p>
    </Content>
</telerik:RadEditor>

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

        if ($telerik.isIE && commandName === "FindAndReplace") {
            updateNbspEntities(editor, true);

            var dialog = editor.get_dialogOpener()._dialogContainers[commandName];
            dialog.add_close(function () {
                updateNbspEntities(editor, false);

            });
        }
    };

    function updateNbspEntities(editor, toAddInNodes) {
        var html = editor.get_html(true);

        if (toAddInNodes) {
            // insert all &nbsp; entities inside nodes to fix IE ranges
            html = html.replace(/((&nbsp;)+)/gi, "<span>$1</span>");
        } else {
            // restore them when FindAndReplace dialog is closed
            html = html.replace(/<span>((&nbsp;)+)<\/span>|<font>((&nbsp;)+)<\/font>/gi, "$1");
        }

        editor.set_html(html);
    };
</script>

Rich Text Editor: Un-bolding html elements inside a bolded parent element creates extra html elements.

Process to recreate

1. Add html element inside a bolded html element (via snippet or in html tab), then un-bold inner html element only.

Example html element inside a bolded html element:

<p>

<strong>

Prior Authorization

<span>inner html element</span>

Interceptor

</strong>

</p>

2. Then un-bold the inner html element on the Design Tab.

Result

The resulting html in the html tab has extra html elements in both sections of surrounding still-bolded text.

<p>

<strong>Prior Authorization <span></span></strong>

<span>inner html element</span>

<strong><span></span> Interceptor</strong>

these pages shows the accessibility standards for tables.
https://www.w3.org/WAI/tutorials/tables/
https://www.w3.org/WAI/tutorials/tables/two-headers/
https://www.w3.org/WAI/tutorials/tables/irregular/

For these two sub links "Tables with two headers" & "Tables with irregular headers", they are looking for "scope=col", "scope=row", "scope=colgroup", "scope=rowgroup".

There doesn't seem to be any built in support for "scope" to be added when using the table wizard, having set on the Accessibility tab a Heading for both a Row & Column.

Add support for "scope" be added to tables created in the Rich Text Editor.

Currently, by using ExternalDialogsPath property, developers can extend the built-in dialogs by adding the user controls in a local folder. It would be a nice-to-have feature, if these user controls can be also located in a virtual folder.

RadEditor allows the copy and paste of images directly into the Editor content area. The Editor converts this images to a base 64 string and includes them in the HTML.

What would really be great is if it could instead convert the image to a file, perhaps even from the base 64 string, and save it server side, and instead add an img tag referencing the saved file. This would be very useful for when the editor is being used for sending emails (less space) and even creating content as the file would be able to be cached.

It's already being done in the TeamPulse product when a screenshot or other image is pasted into the editor. Please extend this functionality to be built into the AJAX version.

It will be possible to use Lightweight render mode with AccessibleRadEditor.
