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.

A JavaScript error is thrown when a hidden AccessibleRadEditor is loaded in IE 10. The error message is:

"SCRIPT5007: Unable to get property 'get_element' of undefined or null reference "

Code to reproduce the issue:

        <asp:Button ID="btn1" runat="server" Text="Show Editor" OnClientClick="showEditor(); return false" />
        <div id="div1" style="display: none">
            <telerik:AccessibleRadEditor ID="AccessibleRadEditor1" runat="server" ></telerik:AccessibleRadEditor>
        </div>
        <script>
            function showEditor() {
                $telerik.$("#div1").show();
            }
        </script>

If the content of the editor contains an inline style which starts with - as -webkit-text-... like in:

<h1 style="-webkit-text-stroke-width: 0px;">My Title</h1>

A server error is thrown:

Server Error in '/' Application.
Name cannot begin with the '-' character, hexadecimal value 0x2D.

A proper workaround for this problem is applying this CSS rule:

div.RadEditor .RadRibbonBar .rrbButton img.rrbButtonImage {
    top:-7px;
}

When the tracking feature is enabled some of the existing features don't work properly. For eg:
a. If existing text were bulleted they were not displayed properly.
b. If bulleted content was copied over from a web page and pasted into the RadEditor control formatting was not retained.
c. If text in the editor that was modified previously and not accepted by a user, a change made to the same text after some time does not capture the new username and date time stamp by the same /different user. 

Please fix the tracking feature for SharePoint

The changes applied to a newly uploaded image through the ImageEditor are not taken into account when inserting the image in RadEditor. The issue is reproducible in all browsers.

Currently the " entity is converted to a single quote under Chrome or Firefox, when ConvertToXhtml filter is enabled and the entity is placed in the value of an HTML attribute, for example href.

When a Hyperlink element is set with an onclick handler, after passing through the Preview mode it is being stripped under IE7. Also related problem is that the link in the Preview mode are clickable and the URL set to the href attribute is opened in new tab/window.

Possible solution for both bugs is to override the function responsible for the conversion of such attributes in the Preview mode with this JavaScript code:

Telerik.Web.UI.Editor.Utils.setTargetsForPreview = function (editor) {
	var contentArea = editor.get_contentArea();
	var links = contentArea.getElementsByTagName("A");
	for (var i = 0, l = links.length; i < l; i++) {
		var link = links[i];
		//handle targets
		var target = link.getAttribute("target");
		if (target != null) {
			link.setAttribute("re_target", target);
		}
		if (target != "_blank")
			link.setAttribute("target", "blank");
		//handle ckick event
		var oldOnClick = (link.getAttributeNode('onclick')
			&& link.getAttributeNode('onclick').value)
			|| link.getAttribute("onclick");

		if (oldOnClick != null) {
			link.setAttribute('re_onclick', oldOnClick);
		}

		link.setAttribute('onclick', 'return false;');

		if (typeof link.onclick === "string") {
			link.onclick = function () {
				return false;
			};
		}
	}
};

Telerik.Web.UI.Editor.Utils.restoreTargetsAfterPreview = function (editor) {
	var contentArea = editor.get_contentArea();
	var links = contentArea.getElementsByTagName("A");
	for (var i = 0, l = links.length; i < l; i++) {
		var link = links[i];
		//handle targets
		var oldValue = link.getAttribute("re_target");
		if (oldValue != null && oldValue != "null") {
			link.setAttribute("target", oldValue);
		}
		else {
			link.removeAttribute("target");
		}
		//handle anchors urls
		var oldOnClick = link.getAttribute("re_onclick");
		link.onclick = null;
		if (oldOnClick != null && oldOnClick != "null") {
			link.setAttribute('onclick', oldOnClick);
		}
		else {
			link.removeAttribute("onclick");
		}
		link.removeAttribute("re_onclick");
		link.removeAttribute("re_target");
	}
};


Note that this script must be placed in a script tag right after the RadEditor control.

The Advanced Mode (embed code) textbox in the Insert External Video dialog is always readonly and you cannot put the code in it.

In the meantime you can use the following workaround that will access the textbox and remove the readonly attribute:

	<telerik:RadEditor ID="RadEditor1" runat="server" OnClientCommandExecuted="OnClientCommandExecuted">
		<Tools>
			<telerik:EditorToolGroup>
				<telerik:EditorTool Name="InsertExternalVideo" />
			</telerik:EditorToolGroup>
		</Tools>
	</telerik:RadEditor>
	<script type="text/javascript">
		function OnClientCommandExecuted(sender, args)
		{
			if (args.get_commandName() == "InsertExternalVideo")
			{
				var extVideoDialog = sender.get_dialogOpener()._dialogContainers["InsertExternalVideo"];
				if(extVideoDialog){
					extVideoDialog.add_pageLoad(editTextbox);
				}
			}
		}

		function editTextbox(sender, args)
		{
			sender.get_contentFrame().contentWindow.document.getElementById("embedCode").removeAttribute("readonly");
			sender.remove_pageLoad(editTextbox);
		}
	</script>

The right side of the ImageManager's upload window is truncated in IE7 - http://screencast.com/t/zB2lWaGXdYd

When indenting list items in ordered list, the created nested list type remains the same.

The problem could be described with the following behavior:
·         Cannot insert a link with the Link Manager;
·         If switched to HTML mode cannot return to Design mode, switching to Preview – allows Design mode.
·         A JavaScript error is thrown on focusing and on editing the content area. 

Possible fixes are: 
o   Removing the Modernizr JavaScript file;
o   Setting the RadEditor with ContentAreaMode="Iframe" property;

The Insert Web Part tool in RadEditor for SP 2010 throws JavaScript error (reproducible in all browsers).

Steps to reproduce:
1. Open http://sharepoint.telerik.com/aspnet-ajax/web-parts/Pages/Content-Editor-Web-Part-using-RadEditor.aspx
2. Click over the content of the Editor, so the toolbar will be shown
3. Click over the Insert Web Part Tool

The value set to the EmptyMessage of the editor floats outside the EDitor if its length exceeds the Editor's width - http://screencast.com/t/rPLVwFVfU

The 'Link Text' text box does not always appear in the Link Manager of RadEditor in IE. Behavior is observed when text in an inline element is selected and Link Manager is opened.

When a new anchor is created and an anchor name is set via the Hyperlink Manager tool of RadEditor, the 'name' attribute will not be applied under IE7. Under IE8 the specified anchor name is set to a 'submitname' attribute of the anchor element.

FIX: RadEditor in an iframe on iPad grows infinitely

The following workaround could be used temporarily:
   <script type="text/javascript">
            Sys.Application.add_load(function () {
                var editor = $find("<%=RadEditor1.ClientID%>");
                var viewportWidth = document.documentElement.clientWidth;
                var viewportHeight = document.documentElement.clientHeight;
                editor.setSize(viewportWidth.toString(), viewportHeight.toString());
                    }
        )
        </script>
