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.
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
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.

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.

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.
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 :)

I cannot clear the content area of the TelerikEditor when the component is placed in the Form Item Template.
<AdminEdit>
Below, you can find a workaround solution:
@using System.ComponentModel.DataAnnotations;
@using Telerik.Blazor.Components.Editor
<TelerikForm Model="@Model" OnSubmit="@OnSubmitHandler">
<FormValidation>
<DataAnnotationsValidator />
<ValidationSummary />
</FormValidation>
<FormItems>
<FormItem>
<Template>
<TelerikEditor @bind-Value="@Model.Name" @ref="@EditorRef" />
</Template>
</FormItem>
</FormItems>
</TelerikForm>
@code {
public SampleData Model { get; set; } = new SampleData();
public TelerikEditor EditorRef { get; set; }
private async Task OnSubmitHandler(EditContext editContext)
{
bool isFormValid = editContext.Validate();
if (isFormValid)
{
//some logic here
}
else
{
await EditorRef.ExecuteAsync(new HtmlCommandArgs("setHtml", "")); //workaround
//clear the content of the editor to let the user type anew
Model.Name = String.Empty;
}
}
public class SampleData
{
[Required]
[MinLength(30, ErrorMessage = "The content should be minimum 30 characters long.")]
public string Name { get; set; }
}
}</AdminEdit>
Highlight an existing hyperlink and click the Insert Hyperlink button. The update button is empty
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).
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>.
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.

I upgraded my Blazor UI package to 3.3.0 to try and get rid of the multiple tbody issue with adding a table. Now there is an even weirder problem. Adding a table with two columns via setting the Editor's value in the code block is causing several table cells to get inserted in between and around the desired ones.
This is my long html string:

This is the result:
At this point I am having to downgrade to 3.2.0 in order for it to look anything near what I need it to.

Thanks.
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.
Steps to reproduce:
https://demos.telerik.com/blazor-ui/editor/overview
1. Clean content
2. Insert sentence
3. Center it and press Enter
4. Type new sentence and select whole content (Ctrl + A)
5. Align not possible, because is selected
Expected: All paragraphs in the editors receive center alignment
Actual: Align is possible
