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>

Hi,

I tried looking through the docs and api reference for the Blazor Editor, but I can't seem to find any resizable property like the one found in the ASP.NET Core component here: ASP.NET Core Editor - Api Reference | Telerik UI for ASP.NET Core

I just wanted to check that this feature is not included in the editor for Blazor before I submitted a feature request. I tried to search the requests as well and I didn't see this request listed. 

If this feature does not exist, do you know if it is being currently considered for a future release or if there is a workaround?

Thank you,

Frank

When you create or paste a table, you cannot move the cursor outside of it if there is no other content in the Editor.

----------ADMIN EDIT----------

Here is a possible workaround when using InsertTable() tool:

@using Telerik.Blazor.Components.Editor

<TelerikButton OnClick="@InsertTable">Insert Table</TelerikButton>

<TelerikEditor @ref="@TheEditor" Value="@TheContent" ValueChanged="@ValueChangedHandler"></TelerikEditor>

@code {
    TelerikEditor TheEditor { get; set; }

    string TheContent { get; set; } = "<p>Lorem ipsum.</p><p>Dolor sit amet.</p>";

    void ValueChangedHandler(string value)
    {
        var checkEnd = value.EndsWith("</table>");

        TheContent = checkEnd == true ? value + "<p></p>" : value;
    }

    async Task InsertTable()
    {
        await TheEditor.ExecuteAsync(new TableCommandArgs(4, 4));
    }
}

Steps:

• Use the Editor's ValueChanged event.
• See if the value ends with a closing </table> tag.
• Append an empty paragraph to the Editor value - "<p></p>".

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.

Please expose the ability to allow additional HTML attributes in the Editor content.

===ADMIN EDIT===

Provide support for:

• custom attributes for the Editor elements
• custom tags

The Telerik Blazor Telerik Editor Insert Hyperlink functionality is not consistent with other Telerik Editor components and non Telerik Editors. Usually when dealing with Editors and the Insert Hyperlink feature, you can insert a hyperlink without need to select and convert existing text. You can also usually use the ctrl+k keyboard shortcut instead of clicking on the button. This does not work in the Telerik Blazor Editor.

The differences and lack of functionality has been raised as an issue by end users.

Expected Behaviour

1. Ensure no text is selected. The Insert Hyperlink button should be enabled.
2. Click the Insert Hyperlink button or press ctrl+k.
3. Enter values for web address, text, tooltip and "open link in new window".
4. Click insert. An anchor tag with the given text, link, etc. is created.

This can be reproduced on any of the Kendo UI for jQuery demo pages. It can also be reproduced within the editor on this very form.

Actual Behaviour

1. Ensure no text is selected. The Insert Hyperlink button is not enabled and cannot be clicked.
2. You must select existing text to be able to convert it to a hyperlink.

This can be reproduced on any of the demo pages that has the hyperlink button.

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.

I am using the LinkCommandArgs to programmatically create a link. I am adding all the required parameters (string href, string text, string target, string title) but no link is added to the Editor content.

For the time being, you may add a link using the HtmlCommandArgs tool and the "insertHtml" command like so: https://blazorrepl.telerik.com/GyuTmMkt56f3YiM754.

When adding an icon such as <i class="fa-light fa-envelope"></i> (the format which FontAwesome recommends), the icon's HTML disappears upon saving. We figured this was maybe due to the type of tag used (the i tag), so we tried using a div instead (<div class="fa-light fa-envelope"></div>). This div is not stripped from the HTML but the icon is not rendered.

Please allow inserting icons in the Editor content.

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"))

The Editor currently supports only numeric ordered list. I'm looking for an option to add different types of ordered lists - roman and alphabetical.

Please add support for these types of ordered lists similiar to the KendoReact Editor.

When I paste a table from Word or Excel in the Editor, some of the formatting is lost. The Kendo React Editor supports most of the formatting and I would like to see the same behavior for Blazor. 

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:

1. Add a table
2. Toggle the Editor
3. Cells appear taller

Here is a scenario that produces an exception.

1. Go to https://demos.telerik.com/blazor-ui/editor/overview
2. Select the image in the Editor and resize it using the border / resize handles.
3. Keep the image selected and then click the "Insert image" button in the toolbar of the editor. Now the page will crash.

I know the indent option is available.

But it would be great if it would be possible to allow tab presses in the editor control. 

Maybe the option to use @onkeydown or a parameter of AllowTabs.

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?
