Example

The following example enables Markdown message rendering. The example uses the Markdig Markdown processing library to convert Markdown text into HTML.

XAML

<dxaichat:AIChatControl
    x:Name="aiChatControl"
    UseStreaming="True"
    ContentFormat="Markdown"
    MarkdownConvert="AiChatControl_MarkdownConvert"
    HorizontalAlignment="Stretch" 
    VerticalAlignment="Stretch" 
    Margin="10">
</dxaichat:AIChatControl>

C#

using DevExpress.Xpf.Core;
using DevExpress.AIIntegration.Blazor.Chat.WebView;
using Microsoft.AspNetCore.Components;
using Ganss.Xss;
using Markdig;

namespace DXApplication {
    var sanitizer;

    public partial class MainWindow : ThemedWindow {
        public MainWindow() {
            InitializeComponent();
            sanitizer = new HtmlSanitizer();
        }

        void AiChatControl_MarkdownConvert(object sender, AIChatControlMarkdownConvertEventArgs e) {
            // Convert Markdown to HTML.
            string html = Markdown.ToHtml(e.MarkdownText);

            // WARNING: The AI agent's content may be untrusted. 
            // Developers must sanitize all HTML before rendering to prevent XSS attacks.
            string safeHtml = sanitizer.Sanitize(html);

            // Assign sanitized HTML for rendering.
            e.HtmlText = (MarkupString)safeHtml;
        }
    }
}
