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?
Hello,
after selecting a block of text in your editor and perform some block operation (for instance - change font size, name, ..) the original selection is lost. Would it be possible to keep that selection please?
Very thanks.

I would like to use the Editor in a more compact matter in my application. The buttons and button groups must be small, and the margins and the paddings must be smaller as well.
The overall goal is to make the Editor take less amount of space in the UI.
Description :
When you click before the content in the Editor, the cursor should show up before the text. But, if a text was added programmatically, the cursor shows up after the added text instead.
To reproduce the problem :
1. Open this REPL example: https://blazorrepl.telerik.com/cdYpPabd37jvK9jt23
2. Click the "Insert Inline Text" button.
3. Try to place the cursor in front of the editor content.
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.
I have the following command
await _editorRef.ExecuteAsync(new HtmlCommandArgs("insertHtml", "<hr class='donotremove' />", false));
Currently, the <hr/> element is added but its class is stripped. This is not the case with other elements.
Reproduction: https://blazorrepl.telerik.com/GRYyGUbH492QNMki44.
Please allow adding class to <hr/> elements, too.
Currently, our Editor component does not support a placeholder parameter. Having a placeholder parameter, similar to the Kendo UI Editor, would prove to be beneficial.
It seems that texts/options in the Format tool dropdown are not part of the localization (Paragraph, Heading 1..6).

ADMIN EDIT

A possible workaround for the time being is to customize the built-in Format tool to add your desired labels for the format options.
Hello,
We've come across a bug. It seems as whatever tool button(s) that should be selected is not shown correctly. It appears to show the previously selected.
Repro steps:
- Write two different formatted texts on separate lines in your Editor component.
- Move the cursor to the first line
- Move the cursor to the second line that has a different formatted text. Note that the tool button for the formatted text on the first line is shown as selected.
This should happen:
Is this an intended behaviour? Our users are confused :)

Hello,
We are adding references to other documents via a drag an drop over the text as a superscript hyperlinks. Our users are complaining that when we drag and drop onto the Blazor editor control, it is hard to see exactly where the drop is going to be.
The Kendo UI Editor supports this.
Please add built-in toolbar tools (buttons) for Cut, Copy and Paste.
The request from our customer is to have similar behavior as typical toolbars in most applications where there is a cut and paste along with the regular keyboard shortcuts.
As the toolbar options typically show the options that are available then one might presume that because cut and paste icons are not present then such a shortcut might not be available either.
Here is a scenario that produces an exception.
- Go to https://demos.telerik.com/blazor-ui/editor/overview
- Select the image in the Editor and resize it using the border / resize handles.
- Keep the image selected and then click the "Insert image" button in the toolbar of the editor. Now the page will crash.
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).

Telerik edit: This was a ProseMirror issue, which was fixed on their side. Changes took effect in Telerik UI for Blazor 5.0.0.
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>.
In Editors that use the ProseMirror engine (including non-Telerik), when you click Enter twice in the middle of formatted text and go back (with an up arrow) to write, the new text format is back to default.
This enhancement will allow you to keep the text format after pressing Enter and creating new block elements.
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.

When I add table to Editor, dispose the component and initialize it again with the same content, the table cells appear taller. It looks like an additional <br class="ProseMirror-trailingBreak"> appears in every cell.
Reproduction: https://blazorrepl.telerik.com/cwaqcSuV12myl9ok47.
Steps to reproduce:
- Add a table
- Toggle the Editor
- Cells appear taller
