Syncfusion Blazor AI AssistView

Build conversational AI interfaces with the Syncfusion Blazor AI AssistView component. This skill provides complete guidance for creating interactive chat applications, AI assistant UIs, and prompt-response systems in Blazor Server, WebAssembly, and Web App projects.

Component Overview

The SfAIAssistView component is a specialized UI control for building AI-powered chat applications. It manages the presentation and interaction model for prompt-response conversations with built-in support for:

• Prompt Management: Input text, suggestions, placeholder text
• Response Handling: Async processing, markdown rendering, streaming support
• Customization: Avatar icons, styling, theme integration
• UX Features: Scroll-to-bottom indicator, conversation history
• Event Integration: PromptRequested events for AI service callbacks

Quick Start

@using Syncfusion.Blazor.InteractiveChat

<div style="height: 400px; width: 600px;">
    <SfAIAssistView 
        Prompt="What is Blazor?" 
        PromptRequested="@OnPromptRequested">
    </SfAIAssistView>
</div>

@code {
    private async Task OnPromptRequested(AssistViewPromptRequestedEventArgs args)
    {
        // Add delay to simulate AI processing
        await Task.Delay(1000);
        
        // Connect to your AI service here (OpenAI, Azure, etc.)
        var response = await GetAIResponse(args.Prompt);
        args.Response = response;
    }
    
    private async Task<string> GetAIResponse(string prompt)
    {
        // Call your AI service API
        // For testing: return a simple response
        return $"<div>Processing your prompt: {prompt}</div>";
    }
}

Common Patterns

Pattern 1: Pre-Initialized Conversation

Load the component with existing conversation history:

<SfAIAssistView 
    Prompts="@conversationHistory" 
    PromptRequested="@OnPromptRequested">
</SfAIAssistView>

@code {
    private List<AssistViewPrompt> conversationHistory = new()
    {
        new AssistViewPrompt { 
            Prompt = "What is C#?", 
            Response = "<div>C# is a modern object-oriented programming language...</div>" 
        }
    };
}

Pattern 2: Guided Suggestions

Use suggestions to help users refine their prompts:

<SfAIAssistView 
    PromptSuggestions="@suggestions"
    PromptSuggestionsHeader="Try asking about:"
    PromptRequested="@OnPromptRequested">
</SfAIAssistView>

@code {
    private List<string> suggestions = new()
    {
        "How does dependency injection work?",
        "Explain async/await patterns",
        "What are Blazor components?"
    };
}

Pattern 3: Custom Avatars

Personalize user and AI identities with custom icons:

<SfAIAssistView 
    PromptIconCss="e-icons e-user"
    ResponseIconCss="e-icons e-bullet-2"
    PromptRequested="@OnPromptRequested">
</SfAIAssistView>
