A possible workaround: take the PageProperties.ascx dialog and use it as an external dialog in your project and change the _setClass: function to

_setClass: function (element, cssClassHolder) { element.className = cssClassHolder.get_value(); } 

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>

We've noticed that when editing an Image Map on an image, the <map> tag will always be placed at the end of the HTML. While this not a problem in general, as most Browsers seem able to understand it, it can break the Image Map if such HTML is viewed in Outlook 2005-2010 under certain conditions:

Steps to reproduce, using the Rad Editor demo:

* create a table with 1 column, and 3 rows.

* Insert an image into the middle row

* Right Click Image -> Image Map Editor -> Add a couple of hot areas

* Close Image Map Editor

The editor will generate HTML from this, that has the <IMG> tag properly placed in the middle row column, but the associated <MAP> tag placed AFTER the closing </TABLE>. This will break the image map in Outlook, because it apparently requires the <map> to be in the same block or inline element as the associated <img>.

Is there a way to make the editor always place the <map> tag immediately after the <img> it belongs to, instead if placing it at the end of the current HTML?

I've had some complaints from user on a page with 2 RadEditors.  If they go to a 2nd page and then hit the 'back' button, all the other controls on the page have what they last typed in, but not the 2 radEditors.
