Setting render mode to auto or lightweight via the web.config does not affect the rendering of RadEditor with markup that is used with FileManager's composite properties. For example, ImageManager-MaxUploadFileSize, ImageManager-ViewPaths, etc. 


For the time being, you can explicitly set the RenderMode property of RadEditor to either Auto or Lightweight in order to resolve the problem. 

When resizing images in RadEditor design mode using the corner-handles the image should retain its aspect ratio. This works very good in Firefox (v. 41.0.2) out-of-the-box because the browser implements that functionality but not in IE (v. 11.0) or Chrome (46.0) in Windows 8.1 (v 6.3, build 9600).

The radeditor is quite a useful control.  It just seems to lack some basic events that you would expect to seen from any input type control.  The control is great for html translation, but if you are using it for user input it could us a few basics. 

Yes, there is a OnClientInlineEditCompleted event that works when you are in InlineEdit mode which is a good start, but InlinEdit mode is not good for all scenarios.  

Take for example when you have a survey with a "time from started" asp:timer.  Each time the timer ticks and you are in InlineEdit mode the menu disappears even when the user is still actively using the radeditor. 

If we are in the same survey.  We can also automatically save the information that was entered by the user if we have either or a on_change or lost_focus event that could be used.  Obviously there are a bunch of menu interactions that could be cause the lost_focus or on_change event to occur, but those could be filtered by the user so they could be caught so you know that you are not actually leaving the radeditor.

Thank you for your consideration.

When creating or updating old areas, the target value always shows either Target or the lastly selected one. It does not update its state.

This feature is available when ContentAreaMode is Iframe.

FileBrowser dialogs cannot upload files greater than 200kb when AsyncUpload is disabled (i.e., the Upload control is used instead). 

ColorPicker inside a RadEditor don't fit inside DropDownBody, the last color jumps down a row. This happens when RadEditor Skin is set MetroTouch and RenderMode to Lightweight.

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:

        <telerik:RadEditor runat="server">

        span a {

        }
    -----------------------------------------------------------------------

            .reContentArea span a {

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.
