    public async Task OnContentChanged()
        contentAsHtml = await richTextEditRef.GetHtmlAsync();
        contentAsDeltaJson = await richTextEditRef.GetDeltaAsync();
        contentAsText = await richTextEditRef.GetTextAsync();

    public async Task OnSave()
        savedContent = await richTextEditRef.GetHtmlAsync();
        await richTextEditRef.ClearAsync();

Editor customization


The RichTextEdit comes default with 2 themes Snow and Bubble. The Snow theme is a simple flat toolbar theme and the Bubble theme is a tooltip based theme where the toolbar will be displayed in the tooltip.
See QuillJS Themes for more information.


The RichTextEdit toolbar can be completely customized. QuillJS defines a number of default actions that can be used through the RichTextEditToolbarButton and RichTextEditToolbarSelect components
See QuillJS Toolbar module for more information.

QuillJS Configuration

The RichTextEdit has the option to inject additional QuillJS configuration logic or load additional modules. Use the ConfigureQuillJSMethod property to indicate which javascript method needs to be called during initialization. If you for example want to change the way how links are sanitized you can use the following logic. Default all user typed url’s are relative to your pages base url. So when a user types this will result in something like https://baseurl/, but if you would probably like then use the following configuration routine.
<RichTextEdit ConfigureQuillJsMethod="myComponent.configureQuillJs" />

@* Define this configuration in a javascript file
    window.myComponent = {
        configureQuillJs: () => {
            var link = Quill.import("formats/link");

            link.sanitize = url => {
                let newUrl = window.decodeURIComponent(url);
                newUrl = newUrl.trim().replace(/\s/g, "");

                if (/^(:\/\/)/.test(newUrl)) {
                    return `http${newUrl}`;

                if (!/^(f|ht)tps?:\/\//i.test(newUrl)) {
                    return `http://${newUrl}`;

                return newUrl;
