Installing

You can install from NuGet using the following command:

Install-Package Blazox.RichTextEditor

Or via the Visual Studio package manger.

Setup

Blazor Server applications will need to include the following CSS and JS files in their Pages\_Host.cshtml (or Pages/_Layout.cshtml if using .Net 6).

In the head tag add the following CSS.

    <link href="//cdn.quilljs.com/1.3.6/quill.snow.css" rel="stylesheet">
    <link href="//cdn.quilljs.com/1.3.6/quill.bubble.css" rel="stylesheet">

Then add the JS script at the bottom of the page using the following script tag.

    <script src="https://cdn.quilljs.com/1.3.6/quill.js"></script>
    <script src="_content/Blazox.RichTextEditor/quill-blot-formatter.min.js"></script>
    <script src="_content/Blazox.RichTextEditor/Blazox-BlazorQuill.js"></script>

NOTE If you're using Blazor WebAssembly then these need to be added to your wwwroot\index.html.

You can add the following using statement to your main _Imports.razor to make referencing the component a bit easier.

@using Blazox.RichTextEditor

Usage

Below is a list of all the options available on the Text Editor.

Templates

• ToolbarContent (optional) - Allows the user to define the Toolbar (above the editor control, or in-line when using the bubble theme, and a user highlights text in the editor).
• EditorContent (optional) - Allows the user to define the initial content

Parameters

• ReadOnly (Optional - Default: false) - Determines if the editor will load in read-only mode. This mode can be toggled.
• Placeholder (Optional - Default: Compose an epic...) - The text to show when editor is empty.
• Theme (Optional - Default: snow) - Use snow to show the Toolbar on top of the editor, and bubble for inline editing.
• DebugLevel (Optional - Default: info) - Determines the level of debug information returned to the web browser console window. Options are error, warn, log, or info.
• MaxLength (Optional) - Determines the max length of the text content of the editor if it is specified.

Methods

• GetText - Gets the content of the editor as Text.
• GetHTML - Gets the content of the editor as HTML.
• GetContent - Gets the content of the editor in the native Quill JSON Delta format.
• LoadContent (json) - Allows the content of the editor to be programmatically set.
• LoadHTMLContent (string) - Allows the content of the editor to be programmatically set.

• InsertText (string) - Inserts text at the current point in the editor.

Events
