Add PenmanQuill to your service collection

Add a reference to the PenmanQuill services to your Program.cs (Wasm) or Startup.cs (Server)

Blazor Server Startup
 public void ConfigureServices(IServiceCollection services)
            services.AddServerSideBlazor().AddCircuitOptions(options => { 
                options.DetailedErrors = true; 
            services.AddPenmanQuill(); //<-- add this
Blazor Wasm Program
Add CSS and Javascript to your Blazor site

Add the following CSS files to _Host.cshtml if you're using Blazor Server or to index.html if you're using Blazor WASM

    <link href="//" rel="stylesheet" />
    <link href="//" rel="stylesheet" />
    <link href="_content/Penman.Blazor.Quill/penman-blazor-quill.css" rel="stylesheet" />

And then do the same with the Javascript files

    <script src=""></script>
    <script src="_content/Penman.Blazor.Quill/quill-blot-formatter.min.js"></script>
    <script src="_content/Penman.Blazor.Quill/penman-blazor-quill.js"></script>

Optional: If you don't want to keep adding the namespace to pages, just add the following using statement to _Imports.razor.

@using Penman.Blazor.Quill


Setting a Quill Theme

Penman.Blazor.Quill supports the two primary Quill Themes

  • Snow (default)
  • Bubble (more of a Medium-style pop-up toolbar experience)

In order to set the theme, do the following

<TextEditor @ref="@_quillEditor" 

Default Toolbar Example

Building the toolbar is easy. You can state what you wish by passing in the Toolbar object.

@using Penman.Blazor.Quill
    Toolbar="new Toolbar { ShowFullToolbar=true }"
    Placeholder="Enter non HTML format like centering...">
@code { 
	TextEditor MyEditor;

Or you can specify the very toolbar elements you want to use.

@using Penman.Blazor.Quill

<TextEditor @ref="@QuillHtml">
        <select class="ql-header">
            <option selected=""></option>
            <option value="1"></option>
            <option value="2"></option>
            <option value="3"></option>
            <option value="4"></option>
            <option value="5"></option>
        <span class="ql-formats">
            <button class="ql-bold"></button>
            <button class="ql-italic"></button>
            <button class="ql-underline"></button>
            <button class="ql-strike"></button>
        <span class="ql-formats">
            <select class="ql-color"></select>
            <select class="ql-background"></select>
        <span class="ql-formats">
            <button class="ql-list" value="ordered"></button>
            <button class="ql-list" value="bullet"></button>
        <span class="ql-formats">
            <button class="ql-link"></button>
        <h4>This Toolbar works with HTML</h4>
        <a href=""></a>
<br />
<button class="btn btn-primary" 
        @onclick="GetHTML">Get HTML</button>
<button class="btn btn-primary"
        @onclick="SetHTML">Set HTML</button>
<br />
    <br />
<br />

@code {

TextEditor QuillHtml;
string QuillHTMLContent;

    public async void GetHTML()
        QuillHTMLContent = await this.QuillHtml.GetHTML();

    public async void SetHTML()
        string QuillContent =
            @"<a href=''>" +
            "<img src='images/BlazorHelpWebsite.gif' /></a>";

        await this.QuillHtml.LoadHTMLContent(QuillContent);

Add fonts

You can add your own fonts to the editor.

@using Penman.Blazor.Quill

    #TestId {
        font-family: "MS Gothic";
        font-size: 18px;
        height: 375px;

    .ql-font-MSGothic {
        font-family: 'MS Gothic';

    .ql-font-Bahnschrift {
        font-family: 'Bahnschrift'

    .ql-font-Impact {
        font-family: 'Impact';

    .ql-font-Courier {
        font-family: 'Courier';

    .ql-font-Comic {
        font-family: 'Comic Sans MS';

<TextEditor Toolbar="new Toolbar { ShowFullToolbar=true }" EditorContainerId="TestId" @ref="@MyEditor" Fonts="Fonts"
            Placeholder="Enter non HTML format like centering...">

    List<string> Fonts = new List<string> { "MSGothic", "Impact", "Courier", "Comic", "Bahnschrift" }; //be sure to set the default font as the first in the list
    TextEditor MyEditor;

Penman.Blazor.Quill is auto-growing by default

You need only style the height of the editor's parent div #ql-editor-container to an appropriate height, and the editor will automatically fill to the size you've specified.


    #ql-editor-container {
    height: 500px;

Advanced functionality

Sticky Snow Toolbar

On longer documents, it becomes tedious and unusable to have the snow toolbar lodged up the top, so instead you can configure the snow editor to have the toolbar follow along as you edit. Simply pass the EditorTheme.Snow for the Theme and StickyToolBar="true"

Note: The bubble editor is not impacted by this at all

<TextEditor @ref="@_quillHtml" 

Wrap Images in Figure elements

While adding images in Quill normally adds an <img src="whatever.jpg"> to the HTML in the final document, it's often useful to wrap img tags in a figure with a caption as in

        <img alt="what to show if no image" src="whatever.jpg">
        <figcaption>This is a caption for our image</figcaption>

Penman.Blazor.Quill creates a figure and figcaption automatically for you around your images.

If you wish to disable this on the editor, simply pass the WrapImagesInFigures="false" on the TextEditor when you create it. This will trigger the default Quill behaviour of simply inserting an <img src="whatever.jpg"> when you add an image to the editor.

<TextEditor @ref="@_quillHtml" 

Detecting user input as the user types

You can hook into the TextEditor's OnTextChanged event handler which will fire whenever the user makes changes inside Quill.

<TextEditor @ref="@_quillHtml" 

Saving Quill Text automatically to your API

To make it possible to auto-save text changes to an API as the user edits the TextEditor content, you simply need to add the TextEditor property TextSavePostUrl which is a string of the URL to POST the text.

<TextEditor @ref="@_quillHtml" 

If Penman.Blazor.Quill detects you've set this URL, it will automatically attempt to post to this URL the contents of the editor. It waits x seconds after the user has stopped typing before firing this so as to not DOS your API endpoint with unnecessary POSTs.

If the POST is successful, you can subscribe to the TextEditor's OnTextSaved event handler to perform whatver actions you want after the API has successfully handled the POST.

<TextEditor @ref="@_quillHtml" 

In addition, you can pass the TextEditor the id to an html element (say a div or span or whatnot) which will show the status of the saving and saved states. Penman.Blazor.Quill will update the inner text of this node with the status as the content is saving or saved.

<div id="my-status-node">
<TextEditor @ref="@_quillHtml"

Quill Server-Uploaded Images

Quill natively uploads images as 64bit encoded embedded images. This is fine in most situations, but for some scenarios, having the image file uploaded like this is unacceptable.

You might want to upload the image to a separate server or API, or even process the file inside your Blazor page. Quill Server-Uploaded Images support the image upload button and drag-and-drop image uploads.

Penman.Blazor.Quill supports two modes for handling server-side image processing.

  • ImageServerUploadType.ApiPost Have javascript perform a fetch POST of the image data to a given url.
  • ImageServerUploadType.BlazorMethod Have javascript send the image data to a delegated Function inside your Blazor page so you can process it yourself.


You can configure API Posting by setting up the TextEditor like this:

<TextEditor @ref="@_quillHtml"

A fetch POST will be called, passing the image as formData attached to the 'imageFile' parameter

const formData = new FormData();
.append('imageFile', file);

It's expected that the configured ImageServerUploadUrl will -- afer processing the image -- return a URL (string) of the image's saved location so Penman.Blazor.Quill can display this in the TextEditor.

Note: For security reasons, Penman.Blazor.Quill passes no http headers of any kind, so if your ImageServerUploadUrl requires such headers, it's recommended that you use a proxy server to receive such a request and add the required headers from the POST before passing it along to the actual image processing server.


You can configure Blazor method uploading in your page by configuring your TextEditor as so:

<TextEditor @ref="@_quillHtml"

Where UploadImageToBlazor is a Func delegate of type Func<string, string, Stream, Task<string>>


private async Task<string> UploadImageToBlazor(string imageName, string imageContentType, Stream imageData)
        //process the image stream and return a string to its url on the interwebs
