The RadEditor is posting multiple symbols when you select to insert a symbol. This happen when the RenderMode is set to LightWeight. The problem is reproducible also when inserting code snippets via the "Insert Code snippet" tool.
video - http://screencast.com/t/DfBMWrW4Px7I

Steps to reproduce:
1. Open http://demos.telerik.com/aspnet-ajax/editor/examples/rendermodes/defaultcs.aspx
2. Try to insert a symbol through "Insert Symbol" command
    Result: Two symbols are inserted instead of one

When creating a list or multiple paragraphs, which have links inside text, applying fore color to the whole text, links does not get affected. 

As a side effect, when only the link is selected and the same color is applied, nothing happens.  

To temporarily improve RadEditor by default to style the links according to the span wrapper elements, you can use the following approach:


 ○ When ContentAreaMode is set to Iframe or not configured:

    ASP.NET
    -----------------------------------------------------------------------
        <telerik:RadEditor runat="server">
            <CssFiles>
                <telerik:EditorCssFile Value="Styles.css" />
            </CssFiles>
            <Content>
                <ul>
                    <li>text <a href="#">link</a> text</li>
                    <li>text <a href="#">link</a> text</li>
                    <li>text <a href="#">link</a> text</li>
                </ul>
            </Content>
        </telerik:RadEditor>
    -----------------------------------------------------------------------

    Styles.css
    -----------------------------------------------------------------------
        span a {
            color:inherit;
        }
    -----------------------------------------------------------------------


 ○ When ContentAreaMode is set to Div:
    -----------------------------------------------------------------------
        <style>
            .reContentArea span a {
                color:inherit;
            }
        </style>

        <telerik:RadEditor runat="server" ContentAreaMode="Div">
            <Content>
                <ul>
                    <li>text <a href="#">link</a> text</li>
                    <li>text <a href="#">link</a> text</li>
                    <li>text <a href="#">link</a> text</li>
                </ul>
            </Content>
        </telerik:RadEditor>
    -----------------------------------------------------------------------

In order to support the described situation in your project you need to further implement a custom logic that transforms the img's src's value to base46. 

You can find attached an example which you can follow. 

I think RadEditor is starting to look like a good processor integration, however to make it really good it should support Shapes, Charts.

The issue is that it does not support then now, but more that it strips them out  of an existing document with then in it when loaded. I personally think this will make our customers mad if we can't have "true" docx loading etc.

Love to see this Editor become the De-facto for developers and this is what it will take.

RadTextBox need to include the ability for Columns. right now any docx that has a column gets stripped out when loaded. most business documents we deal with have columns.

I have found this feature in other competitive products so i hope Telerik has on on the roadmap and implements it soon.

Did telerik rich text editor check arabic language with the spell checker ?

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. 

Workaround:

<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>
</telerik:RadEditor>

<script>
    function OnClientLoad(sender, args) {
        sender.add_spellCheckLoaded(spellCheckLoaded)
    }

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

        spell.add_spellCheckEnd(function (sender, args) {
            editor.set_html(editor.get_html(true));
        });
    }
</script>

The click event of the button is not prevented and the native anchor behavior occurs. This causes the page to scroll to the top and a # to appear in the URL. 

You can use the following code snippet to prevent the native click behavior of the anchor element and workaround the issue:

<telerik:RadEditor runat="server" ID="RE1" ToolbarMode="Floating" OnClientLoad="OnClientLoad"></telerik:RadEditor>

<script>
    function OnClientLoad(sender, args) {
        $telerik.$(".RadEditor a[title='Toggle Floating Toolbar']").attr("href", "javascript:void(0);")
    }
</script>

When link is given to any image or text, Unlink command should get enabled. But it gets enabled for text only while remains disabled for images.

The issue has been reproducible since 2015 Q1 release

Another post appears as "Provide ability to paste/insert images from clipboard/local drive directly into RadEditor" and talks about similar but to date a facility does not exis as I envisage.

When I work with for example a web mail facility like Yahoo Mail I am using an editor like RadEditor to create my email. When I say I want to attach a file this editor assumes that the file will come from my local drive (rather than a Yahoo server). This is what I would like to see as an option for Radeditor image handling - something like a button that says "upload". Clicking on it takes you to a dialogue to simply upload from local into the document. I appreciate that uploading from local can be done with existing Radeditor Image manager but this also offers access to server space that in the case of e.g. web mail is irrelevant and confusing.

In an ideal world I would also like the uploaded document to be automatically associated with the document (email) that it has been loaded into although that can of course be handled manually.

When link is given to image or text, Unlink command should get enabled. But it gets enabled for text only while remains disabled for images. 

To get a better understanding, please refer to the following video:

ContentEditable=true attribute is added to the body element of the Editor's content when resizing a table in RadEditor in Chrome.

Hi,
There is a bug with the "Play" parameter while I insert a SWF movie.
If I uncheck this parameter, the movie still play in Chrome/Mozilla.
This bug is  from this parameter that isn't added in the Embed tag although it is in the object tag.

Example :
<object classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" width="150" height="150">
<param name="Movie" value="/aspnet-ajax/Editor/images/UserDir/Marketing/Reporting_banner.swf">
<param name="play" value="false">
<param name="quality" value="high">
<param name="wmode" value="transparent">
<param name="loop" value="false">
<param name="menu" value="false"><embed src="/aspnet-ajax/Editor/images/UserDir/Marketing/Reporting_banner.swf" width="150" height="150" type="application/x-shockwave-flash" pluginspage="http://www.macromedia.com/go/getflashplayer" quality="high" wmode="transparent" loop="false" menu="false"></object>

Thanks a lot
Chris.

This will enable developers to easily change this property without customizing the FileBrowser dialog.

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.

The error causes the editor's content area not to render. 

The following script can be used as a temporary workaround:

<telerik:RadEditor runat="server" ID="RadEdior1" OnClientSelectionChange="OnClientSelectionChange">
</telerik:RadEditor>

<script type="text/javascript">
    function OnClientSelectionChange(editor, args) {
        if (!editor.getSelectedElement()) {
            editor.focusFirstText();
        }
    }
</script>

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>
