When pulling html from a database into the editor it alters the html. 

For example: 
<table>
    <tr>
         <td style="width:100px;background-color:#FF0000;">Test</td> 
   </tr>
</table>
Is modified to..
<table class="k-table"><tbody><tr><td><p>Test</p></td></tr></tbody></table>

Losing the style attributes and adding classes and paragraph tags breaking our current formatting requirements.

Ideally we would just modify our html data to fit the new formatting but with years of data that's just not feasible.

Release 3.0.0
Add a TelerikEditor to your page with a Link as one of the tools. Open the link dialog and inspect the element for the "Title:" label. It has the call "k-form-field" instead of "k-form-label". This is causing alignment issues with the web address field, and is possible to fix in client code, but requires overriding a lot of built-in styles and would be a much easier fix in Telerik directly

Previously if content in HTML view of Editor exceeded height a scroll bar would appear like below (v2.29).

Now there is no scroll bar and you have to press the down arrow to get further in the content (v.3.0.1) .

to fix this locally I added CSS overflow: auto to .k-textarea

Hi,

We are using the Blazor Editor for a feature in one of our web apps, and created a custom tool for the editor that allows the user to modify the raw HTML.

If an IFrame is added to the HTML with an empty or missing "src" attribute like so:

<iframe src=""></iframe>

OR

<iframe></iframe>

The editor will throw a JS Interop exception:

No value supplied for attribute src
      OP@https://[redacted]/_content/Telerik.UI.for.Blazor/js/telerik-blazor.js:6:830821
      PP.prototype.computeAttrs

Would you guys consider this a bug with the editor? Since they are technically valid elements, mganss' HtmlSanitizer does not remove sourceless IFrames and unfortunately there does not seem to be a way to make it do so.

Thanks in advance for the assistance!

We have a survey page that has multiple editor fields in it.  They need to accept rich text from a paste or other keyboard commands, but we do not want to waste the vertical space for the toolbar appearing in each editor field.

Please update the editor to hide the toolbar if the List<IEditorTool> collection is empty.

This change would make it much easier and less fragile than removing the toolbar to through Css.

It would be nice to have an ability to group CustomTool / icons much like we can do EditorButtonGroup(s) - e.g.

new CustomToolGroup (new CustomTool("Save"),  new CustomTool("Import"), new CustomTool("Export"))

Release 2026 Q1 (Feb)

Description

Regression introduced in v9.0.0.

Initial binding to a property works, but when either the RemoveAttributes or the StripTags parameter is set, on changing the Editor value, two-way binding does not work and the new Editor value is not reflected in the property value.

Potentially related to #3887

Steps To Reproduce

  1. Run the following example:
<p role="status">Current Editor value: @CurrentEditorText</p>

<TelerikEditor @bind-Value="@CurrentEditorText">
    <EditorSettings>
        <EditorPasteSettings ConvertMsLists="@true"
                             RemoveAllAttributes="@true"
                             RemoveAttributes="@(new List<string> { "lang" })"
                             RemoveHtmlComments="@true"
                             RemoveMsClasses="@true"
                             RemoveMsStyles="@true"
                             StripTags="@( new List<string> { "h1" })">
        </EditorPasteSettings>
    </EditorSettings>
</TelerikEditor>


@code {
    private string CurrentEditorText { get; set; } = @"<strong>initial</strong><span>value</span>";

    public List<string> RemoveAttributes { get; set; } = new List<string>() { "data-id" };

    public List<string> StripTags { get; set; } = new List<string>() { "font" };
}
  1. Type in the Editor's content area

Actual Behavior

The CurrentEditorText property value is not updated.

Expected Behavior

The CurrentEditorText property value is updated.

Even if setting ReadOnly="true", tables in the Editor can be resized...

This only happens in Iframe mode!


<TelerikEditor Height="300px" @bind-Value="@Value" EditMode="Telerik.Blazor.EditorEditMode.Iframe" ReadOnly="true">
</TelerikEditor>

@code {
    public string Value { get; set; } =
            @"
<table>
    <tbody>
        <tr>
            <td>
               Some text
            </td>
        </tr>
        <tr style=""height: 24px"">
        </tr>
        <tr>
            <td>
                Some text
            </td>
        </tr>
    </tbody>
</table>
    ";
}
