Right now the end user can resize the table cells only through the provided interface in the Table Wizard and Properties inspector module. It will be useful this to be enabled as resize handlers directly in the table as it is implemented in the Kendo Editor - https://demos.telerik.com/kendo-ui/editor/index.

Release 2026 Q2
I am currently using the Radeditor "Insert Table" function. I would like this to allow user to auto adjust columns and rows live just like the following demo. https://demos.telerik.com/aspnet-mvc/editor.  I have disable the table wizard and table properties, so user will not be able to mess with this extra stuff. In the Capture.PNG is what I currently have. I would like to have the Want.PNG picture.

When inserting video in Telerik Editor, radEditor by default inserts it using <embed>.
This element is not supported by Edge. Many modern browsers now support/recommend to use of the <video> tag.
So, that it will render video in most of Chromium browsers out there.

Discovered that the screen reader is not announcing the select list options. The previous ticket made these keyboard accessible and selectable.  Right now, the use of a screen reader only announces: 

With JAWS
Paragraph Style button menu
Font Name button menu
Real Font button menu
Zoom button menu

With NVDA
Paragraph Style sub menu
Font Name sub menu
Real Font sub menu
Zoom sub menu

 

Using Alt+down arrow to expand the select option menu, using the arrow keys to navigate down the menu nothing is announced although you can visually see the focus highlight in the menu.

This is the same for the two screen readers JAWS and NVDA. Same result when testing on Edge and Chrome browsers.

Other menu options or expandable sections are having a similar issue for:

Paste Options
Foreground Color
Background Color
Paint Stripper
Insert Symbol
Insert Table
Module Manager this one is empty when it expands

Thank you.

There are some areas within the RADEditor that do not support localization:

1. Alerts for Accept All and Reject All track changes.
2. The Comments user interface.
3. Certain strings in the Undo menu.

See attached.

Hi, 

We need to add an aria-label attribute to the RadEditor toolbar link buttons to match the title attribute text. I have been successful using JQuery on other controls to improve accessibility, but this one is not working. It appears because the link button is not rendered since is a pseudo element using the ::before. I have been unable to inject the attribute on page load. 

The issue is for screen readers the editor buttons are not announced when using the arrow key navigation which is called virtual mode. The buttons do announce when using the tab key which is called forms mode.

If this can be a bug fix it would benefit everyone, otherwise, if you have a code suggestions that is helpful. Image attached. 

Thank you.

The newly introduced StripJavaScriptUris security filter is incorrectly identifying and removing legitimate base64-encoded image data URIs (e.g., data:image/png;base64,...) from RadEditor content. The filter treats these safe image URIs as potential XSS threats and strips them along with dangerous JavaScript URIs.

Following  the bug report Cell Properties - Preview only shows top-left cell styling when applying changes to multiple top-row cells > when we navigate the mouse up and down, in the background, we can see only the top left cell with the border we configured. (while initially we selected the top three) > But if now, in the preview page, we will choose the top three > OK >We will see the top three cells showing the design we configured.

When we edit the widget > click on the table on a random cell > select Table Properties > The table wizard will always default to the top left cell > This is working as expected.
If you click in the table (not the editor) and select Cell Properties > the wizard will display (highlight) the cell you selected in the table is it expected that when selecting table properties it always default to the left side first box but when selecting cell properties it will show the current cell which we are in.

Hello Team,

In Editor, proportional resize of image (by holding Shift and dragging) is not working unlike in Word.

Could you please suggestion for adding the same in Editor.


Thanks.

Release R2 2023
Currently we are in the process of securing our web sites. we are experiencing issue on Xhtml Validator in RadEditor where it is not properly loading due to mixed content issue. There is no way to redirect to HTTPS instead of HTTP site.

We can reproduce this on Rad Editor Demo site by making site as HTTPS and click on XHTML Validator icon.

https://demos.telerik.com/aspnet-ajax/editor/examples/overview/defaultcs.aspx

Could you please add that feature?

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.

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>

Such tools exist in Word 2013 - 'Show Markup' and 'Display for Review' tools.

They are used by the users to be able to see the originally typed text, the final results (as if the track changes were accepted) and some further options for the visual appearance of the tracked text.

Such option would be very useful in the RadEditor, because in a large text where multiple users would add their suggestion, redaction and comments, the text would go quite unordered and difficult to be handled with.

In MS Word, if the entire list item is selected, changing the font-size will change the character's formatting too. While selecting only a text node (e.g., without highlighting) will not apply formatting to the list item.

In the RadEditor there is no option to somehow control the size of the bullet points. The only way is the user to switch to HTML mode and manually add font-size attribute in the <li> element.

It would be nice if there is a possibility to change the formatting similar to the editing experience in MS Word.
