If the editor's HTML markup contains inline CSS styles, and a CSS attribute value includes a semicolon (;), it breaks the applied styles and throws an exception.
For example:
<p style= "" ....background-image: url('data:image/png;base64...;""</p>The exception is:
Uncaught TypeError: Cannot read properties of undefined (reading 'trim')
=== ADMIN EDIT ===
The issue can also occur when there is an invalid inline style with two semicolons without a complete style-value pair in-between.
For example:
<p style=""color:red; b ;"">sdf</p>
Clicking the image, and selecting the image button brings up a popup. The "Update" button is not appearing properly (does not occur on other editor popups):

At the moment, the insertHTML command is a block command - meaning, it will wrap your content in a <p> tag if it is an inline tag (such as an anchor).
I would like to be able to insert inline content as well without it getting wrapped in a block parent.

Please review your demo at https://demos.telerik.com/blazor-ui/editor/overview in Safari on MacOS and you'll see that the HTML Editor's height is not showing correctly.
If I click accidentally click on one of the alignment options, I cannot then unselect it.

At the moment bullet lists are lost.

Short version: The editor must implement content filters that transform the HTML MS Word provides into actual HTML (e.g., bullets from Word come as paragraphs, not <ul>).
Long version:
By default, pasting content from an application to another application goes through the OS and the applications can choose what flavor of the content to provide. In the case of pasting to a browser, the browser informs MS Word to provide an HTML version of the content. What Word provides is often pretty bad HTML where a lot of the formatting is gone.
For example, bullet lists become paragraphs that have a span with a dot in it, but this is not a real bullet list.
You can compare that behavior between the Telerik editor and the naked behavior of the browser with markup like this:
<div contenteditable="true" style="min-height: 200px; border: 1px solid red;"></div>
<TelerikEditor></TelerikEditor>An editor component will do some processing that tries to ensure valid HTML and so some content changes are inevitable. The key thing is that we preserve the main HTML structure that Word provides.

A workaround is to initialize the RemoveAttributes list:
<TelerikEditor @bind-Value="@EditorContent">
<EditorSettings>
<EditorPasteSettings
RemoveAttributes="@( new List<string>() )"
>
</EditorPasteSettings>
</EditorSettings>
</TelerikEditor>
@EditorContent
@code{
string EditorContent { get; set; }

When you paste a table in the Editor or insert one through the InsertHTML tool, most of the Editor Table tools don't work on the pasted table. Only Delete Table tool can be used. The rest of the Table tools do not seem to invoke any action with the table.
If you create table using the Create Table tool this behavior is not present, you can accordingly apply the built-in Table tools.
Hi!
When using the Telerik Editor for Blazor, especially the insert HTML function, something seems a little odd.
I reproduced the same behaviour of my application in your demos on your website.
It seems like it is currently not possible to insert a HTML with multiple Lines in it, it only inserts the first line within the given value.
For better understanding, I've attached a video which displays the behaviour.
The HTML i've used:
<p>Test</p><p><br /></p><p>with</p><p><br /></p><p>Line</p><p><br /></p><p>breaks</p><p><br /></p><p><br /></p><p>1</p><p><br /></p><p>2</p><p><br /></p><p>3</p><p><br /></p>
Especially when you are working with HTML-Templates, it is necessary to be able to insert a rich HTML Template with multiple lines, tables, etc..
Thank you for your help in advance!
Best regards,
Stefan
The Editor is missing some CSS styles when the EditMode is Div. As a result, the table resizers are misplaced and table cell borders are missing.
The workaround is to add those styles explicitly, until the issue is fixed.

Hello,
If the Edtor content includes <br /> tags, they will be lost if the user copy-pastes them to a plain text environment such as Notepad or a <textarea>.
Hello,
I expect Shift + Ins to behave like a standard paste (Ctrl + V), but instead, it behaves like a plain text paste (Ctrl + Shift+ V).

The TelerikEditor demos all show bind-Value being used to marshal HTML in and out of the editor:
<TelerikEditor @bind-Value="@TheEditorValue" Width="650px" Height="400px"></TelerikEditor>However, this causes problems - the underlying ProseMirror component emits it's own HTML (e.g. for image drag handles), which is visible in the bound Value property.
We need to be able to export "clean" HTML from the viewer, otherwise we end up saving this superflous HTML as part of our document.
Code
This REPL shows the issue:
https://blazorrepl.telerik.com/mHODmObJ36vZ7ivR09
@page "/editor/tools"
@using Telerik.Blazor.Components.Editor
<TelerikEditor Tools="@EditorToolSets.All"
Height="300px"
@bind-Value="@Value"
EditMode="EditorEditMode.Div"
></TelerikEditor>
<pre style="white-space: pre-wrap;">@Value</pre>
@code {
public string Value { get; set; } =
"<img src=\"img/toolbar-assets/repl-logo.svg\" />";
}Steps to Reproduce
1. Open the REPL and click "Run" - observe that the bound HTML is simply
<img src="img/toolbar-assets/repl-logo.svg" />2. Click on the Telerik logo image inside the editor - observe that the bound HTML is now
<p><img src="img/toolbar-assets/repl-logo.svg" contenteditable="false" draggable="true" class="ProseMirror-selectednode"><div class="k-editor-resize-handles-wrapper ProseMirror-widget" style="width: 857px; height: 78px; top: 8px; left: 8px;" contenteditable="false"><div class="k-editor-resize-handle southeast" data-dir-image-resize="southeast"></div><div class="k-editor-resize-handle east" data-dir-image-resize="east"></div><div class="k-editor-resize-handle south" data-dir-image-resize="south"></div><div class="k-editor-resize-handle north" data-dir-image-resize="north"></div><div class="k-editor-resize-handle west" data-dir-image-resize="west"></div><div class="k-editor-resize-handle southwest" data-dir-image-resize="southwest"></div><div class="k-editor-resize-handle northwest" data-dir-image-resize="northwest"></div><div class="k-editor-resize-handle northeast" data-dir-image-resize="northeast"></div></div><br class="ProseMirror-trailingBreak"></p>
3. Deselect the image - observe that the bound HTML no longer contains the image handles etc, but is still more verbose than when we started
<p><img src="img/toolbar-assets/repl-logo.svg" contenteditable="false" draggable="true" class=""><br class="ProseMirror-trailingBreak"></p>
4. At any point during the above steps, click the "View HTML" button in the Editor toolbar - observe that it is able to present a "clean" structure which contains no ProseMirror markup etc.
Requirements
How do we access this HTML via the TelerikEditor Blazor APIs?
The Editor is not showing its Value in the following scenario:
- Using JSInterop in OnAfterRenderAsync
- Setting the Editor Value in OnAfterRenderAsync and after the JSInterop call
- Blazor Server app (seems to work in WebAssembly)
Possible workarounds are:
- Set the Editor Value and call StateHasChanged() before using JSInterop in OnAfterRenderAsync, or
- Add some small delay (for example, await Task.Delay(100); ) before using JSInterop.
Please allow the user to copy an image from the file system (for example, Windows Explorer) and paste it in the Editor without opening the image first.
Currently this works in the Kendo UI jQuery Editor.
Try running an editor with content like this:
<p>Para 1</p><p><br></p><p>Para 2</p><p><br></p><p>Para 3</p>
Now, open the ViewHtml button from the full toolset and Update the content without modifying anything.
The result is that there are more <br> tags in the the empty paragraphs than what we started with, and they are added every time you repeat this process.
