Format code block using toolbar in Blazor RichTextEditor Component

13 Dec 20211 minute to read

You can configure code block formatting as a separate toolbar button by adding the InsertCode Command within the RichTextEditorToolbarSettings - Items property. The InsertCode button has a toggle state to apply code block formatting to the editor and remove code block formatting from the editor.

The following code will configure the InsertCode button in toolbar and set the background color to “pre” tag for highlighting the code block.
