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>".

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.

When you paste a table in the Editor or insert one through the InsertHTML tool, the Editor adds two  <tbody> tags making this invalid HTML.

If you include a table in the initially rendered content (not pasting it afterwards), two <tbody> tags appear as well.

If you create table using the Create Table tool this behavior is not present, only one <tbody> tag is added as expected.

I am using the InsertHTML command to insert some HTML content. However, it looks like it inserts only the first element from the value I am providing.

Workaround:  you can wrap the HTML content you want to insert in a container, so the InsertHTML command reads it as one element. The following sample demonstrates how to achieve that.

@using Telerik.Blazor.Components.Editor

<TelerikButton OnClick="@( () => WindowIsVisible = !WindowIsVisible )">Insert Html</TelerikButton>

<TelerikEditor @ref="@TheEditor" @bind-Value="@TheContent"></TelerikEditor>

<TelerikWindow @bind-Visible="@WindowIsVisible">
    <WindowTitle>
        <strong>Insert Html</strong>
    </WindowTitle>
    <WindowContent>
        <TelerikTextArea @bind-Value="@HtmlToInsert"></TelerikTextArea>
        <TelerikButton OnClick="@InsertHtml">Insert</TelerikButton>
    </WindowContent>
</TelerikWindow>

@code{

    public string HtmlToInsert { get; set; }

    bool WindowIsVisible { get; set; }

    TelerikEditor TheEditor { get; set; }

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

    async Task InsertHtml()
    {
        await TheEditor.ExecuteAsync(new HtmlCommandArgs("insertHtml", $"<div>{HtmlToInsert}</div>"));

        WindowIsVisible = !WindowIsVisible;

        HtmlToInsert = "";
    }
}

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; }
}

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; }
    }
}

I'm trying to use the Blazor editor but the "Insert Image" function is very basic. Previously using Webforms & Core the insert image in the editor presented the user with a file management and image upload popup. Is this functionality available with the Blazor component?

=====ADMIN EDIT=====

Possible alternative:

1. Utilize a custom Editor's tool that opens a Window or Dialog containing a FileManager.
2. Use the FileManager's SelectedItemsChanged event to determine which image the user wants to insert into the Editor.
3. Programmatically execute the Editor's insertImage command.

Highlight an existing hyperlink and click the Insert Hyperlink button. The update button is empty

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.

If I click accidentally click on one of the alignment options, I cannot then unselect it.

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.

In fashion similar to the following example for the React editor that's done through the onMount ReactJS-specific event: https://www.telerik.com/kendo-react-ui/components/editor/plugins/#popup-tools

I am passing an HTML table, which, on some elements, has a style attribute. When it renders the style attribute is missing which breaks the layout.

Passed HTML:

<table>
    <tr>
         <td style="width:100px;background-color:#FF0000;">Test</td> 
   </tr>
</table>

Rendered HTML from the Editor (missing style attribute):

<table class="k-table"><tbody><tr><td><p>Test</p></td></tr></tbody></table>
