Quick Start Example

Here's a minimal working example to verify your setup:

@using Syncfusion.Blazor.InteractiveChat
@using Syncfusion.Blazor.Buttons

<div style="height: 350px; width: 650px;">
    <SfButton id="aiButton" IsPrimary="true" @onclick="OnButtonClick">
        Ask AI
    </SfButton>
    <div id="editableText" contenteditable="true" style="border: 1px solid #ddd; padding: 10px; margin-top: 10px;">
        <p>Enter your text here for AI processing...</p>
    </div>
    <SfInlineAIAssist @ref="inlineAssist" 
                      RelateTo="#aiButton" 
                      PromptRequested="OnPromptRequested">
        <ResponseActions ItemSelect="OnResponseItemSelect"></ResponseActions>
    </SfInlineAIAssist>
</div>

@code {
    private SfInlineAIAssist inlineAssist = new();

    private async Task OnButtonClick()
    {
        await inlineAssist.ShowPopupAsync();
    }

    private async Task OnPromptRequested(PromptRequestedEventArgs args)
    {
        // Connect to your AI provider here (Azure OpenAI, OpenAI, etc.)
        // For this example, return a simple response
        string response = $"Processing your request: {args.Prompt}";
        await inlineAssist.UpdateResponseAsync(response, true);
    }

    private async Task OnResponseItemSelect(ResponseItemSelectEventArgs args)
    {
        if (args.Item.Label == "Accept")
        {
            await inlineAssist.HidePopupAsync();
        }
        else if (args.Item.Label == "Discard")
        {
            await inlineAssist.HidePopupAsync();
        }
    }
}

Common Patterns

Pattern 1: Content Summarization

<SfButton id="summarizeButton" @onclick="OnSummarizeClick">
    Summarize
</SfButton>

<SfInlineAIAssist @ref="inlineAssist" 
                  RelateTo="#summarizeButton"
                  PromptRequested="OnSummarizeRequest">
</SfInlineAIAssist>

@code {
    private async Task OnSummarizeClick()
    {
        await inlineAssist.ShowPopupAsync();
    }

    private async Task OnSummarizeRequest(PromptRequestedEventArgs args)
    {
        // Send to AI provider with system prompt:
        // "Summarize the following text in 2-3 sentences: " + selectedText
        await inlineAssist.UpdateResponseAsync(summaryResult, true);
    }
}

Pattern 2: Custom Commands

<SfInlineAIAssist @ref="inlineAssist" PromptRequested="OnPromptRequested">
    <CommandMenu Commands="commandItems"></CommandMenu>
</SfInlineAIAssist>

@code {
    private List<CommandItem> commandItems = new List<CommandItem>
    {
        new CommandItem { Label = "Summarize", Prompt = "Summarize this text", IconCss = "e-icons e-collapse-2" },
        new CommandItem { Label = "Translate", Prompt = "Translate to Spanish", IconCss = "e-icons e-translate" },
        new CommandItem { Label = "Rewrite", Prompt = "Rewrite in professional tone", IconCss = "e-icons e-edit" }
    };
}

Pattern 3: Response Management

<SfInlineAIAssist @ref="inlineAssist" PromptRequested="OnPromptRequested">
    <ResponseActions Items="customResponseItems" ItemSelect="OnResponseAction">
    </ResponseActions>
</SfInlineAIAssist>

@code {
    private List<ResponseItem> customResponseItems = new()
    {
        new ResponseItem { Label = "Regenerate", IconCss = "e-icons e-refresh", Tooltip = "Generate new response" },
        new ResponseItem { Label = "Copy", IconCss = "e-icons e-copy", Tooltip = "Copy to clipboard" },
        new ResponseItem { Label = "Insert", IconCss = "e-icons e-insert", Tooltip = "Insert into document" }
    };
}

Key Props

Programmatic Methods

The Inline AI Assist component provides async methods for programmatic control:

ShowPopupAsync()

Opens the AI Assist popup at the RelatedTo element position:

@ref="inlineAssist"

private SfInlineAIAssist inlineAssist;

private async Task OpenAIAssist()
{
    await inlineAssist.ShowPopupAsync();
}

HidePopupAsync()

Closes the AI Assist popup:

private async Task CloseAIAssist()
{
    await inlineAssist.HidePopupAsync();
}

UpdateResponseAsync(string response, bool isFinal)

Sets or streams the AI response content:

private async Task OnPromptRequested(PromptRequestedEventArgs args)
{
    // Non-streaming response
    await inlineAssist.UpdateResponseAsync("Generated response", true);
    
    // Streaming response (call multiple times)
    foreach (var chunk in streamedResponse)
    {
        await inlineAssist.UpdateResponseAsync(chunk, false);
    }
    // Final call with isFinal=true
    await inlineAssist.UpdateResponseAsync(lastChunk, true);
}

ExecutePromptAsync(string prompt)

Programmatically execute a prompt without user input:

private async Task ExecuteSamplePrompt()
{
    await inlineAssist.ExecutePromptAsync("Summarize the selected text in 2 sentences");
}

ShowCommandPopupAsync()

Opens the command menu popup programmatically. The main popup should be open first.

private async Task OpenCommands()
{
    await inlineAssist.ShowPopupAsync();
    await inlineAssist.ShowCommandPopupAsync();
}

HideCommandPopupAsync()

Closes the command menu popup programmatically.

private async Task CloseCommands()
{
    await inlineAssist.HideCommandPopupAsync();
}
