Quick Start Example

Basic Chat Interface

using Syncfusion.WinForms.AIAssistView;
using System.ComponentModel;
using System.Collections.ObjectModel;

namespace AIAssistViewDemo
{
    public partial class Form1 : Form
    {
        ViewModel viewModel;
        
        public Form1()
        {
            InitializeComponent();
            viewModel = new ViewModel();
            
            // Create AI AssistView
            SfAIAssistView sfAIAssistView1 = new SfAIAssistView();
            sfAIAssistView1.Dock = DockStyle.Fill;
            this.Controls.Add(sfAIAssistView1);
            
            // Bind messages
            sfAIAssistView1.DataBindings.Add("Messages", viewModel, "Chats", 
                true, DataSourceUpdateMode.OnPropertyChanged);
        }
    }
    
    // ViewModel
    public class ViewModel : INotifyPropertyChanged
    {
        private ObservableCollection<object> chats;
        private Author currentUser;
        
        public ViewModel()
        {
            this.Chats = new ObservableCollection<object>();
            this.CurrentUser = new Author { Name = "John" };
            this.GenerateMessages();
        }
        
        private async void GenerateMessages()
        {
            // User message
            this.Chats.Add(new TextMessage 
            { 
                Author = CurrentUser, 
                Text = "What is Windows Forms?" 
            });
            
            await Task.Delay(1000);
            
            // Bot response
            this.Chats.Add(new TextMessage 
            { 
                Author = new Author { Name = "Bot" }, 
                Text = "Windows Forms is a GUI framework for building Windows desktop applications." 
            });
        }
        
        public ObservableCollection<object> Chats
        {
            get => this.chats;
            set
            {
                this.chats = value;
                RaisePropertyChanged("Chats");
            }
        }
        
        public Author CurrentUser
        {
            get => this.currentUser;
            set
            {
                this.currentUser = value;
                RaisePropertyChanged("CurrentUser");
            }
        }
        
        public event PropertyChangedEventHandler PropertyChanged;
        
        public void RaisePropertyChanged(string propName)
        {
            PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(propName));
        }
    }
}

Common Patterns

Pattern 1: Chat with Suggestions

// In ViewModel
private IEnumerable<string> suggestion;

public IEnumerable<string> Suggestion
{
    get => this.suggestion;
    set
    {
        this.suggestion = value;
        RaisePropertyChanged("Suggestion");
    }
}

// Set suggestions after bot response
Suggestion = new ObservableCollection<string> 
{ 
    "Tell me more", 
    "What are alternatives?" 
};

// In Form
sfAIAssistView1.DataBindings.Add("Suggestions", viewModel, "Suggestion", 
    true, DataSourceUpdateMode.OnPropertyChanged);

Pattern 2: Typing Indicator During AI Processing

// In ViewModel
private bool showTypingIndicator;

public bool ShowTypingIndicator
{
    get => this.showTypingIndicator;
    set
    {
        this.showTypingIndicator = value;
        RaisePropertyChanged("ShowTypingIndicator");
    }
}

// Usage
ShowTypingIndicator = true;
var response = await GetAIResponse(userMessage);
Chats.Add(new TextMessage { Author = botAuthor, Text = response });
ShowTypingIndicator = false;

// In Form
sfAIAssistView1.DataBindings.Add("ShowTypingIndicator", viewModel, 
    "ShowTypingIndicator", true, DataSourceUpdateMode.OnPropertyChanged);
    
sfAIAssistView1.TypingIndicator.Author = new Author 
{ 
    Name = "Bot", 
    AvatarImage = Image.FromFile(@"Assets\bot.png") 
};
sfAIAssistView1.TypingIndicator.DisplayText = "Typing";

Pattern 3: Custom Banner

BannerStyle customStyle = new BannerStyle
{
    TitleFont = new Font("Segoe UI", 14F, FontStyle.Bold),
    SubTitleFont = new Font("Segoe UI", 12F, FontStyle.Italic),
    ImageSize = AvatarSize.Medium,
    SubTitleColor = Color.Gray,
    TitleColor = Color.DarkBlue
};

string title = "AI Assistant";
string subTitle = "Powered by OpenAI";
sfAIAssistView1.SetBannerView(title, subTitle, 
    Image.FromFile(@"Assets\ai-icon.png"), customStyle);

Pattern 4: Prompt Validation

sfAIAssistView1.PromptRequest += (sender, e) =>
{
    var message = e.Message as TextMessage;
    if (message == null) return;
    
    // Validate input
    if (string.IsNullOrWhiteSpace(message.Text))
    {
        e.Handled = true; // Prevent adding to messages
        MessageBox.Show("Please enter a message.");
        return;
    }
    
    // Custom processing
    LogUserInput(message.Text);
};

Installation

Install-Package Syncfusion.SfAIAssistView.WinForms

For OpenAI integration:

Install-Package Microsoft.SemanticKernel

Troubleshooting

Messages not displaying:

• Verify data binding is set correctly
• Ensure ObservableCollection is used (not List)
• Check that RaisePropertyChanged is called on collection updates

Typing indicator not showing:

• Set ShowTypingIndicator = true before async operation
• Configure TypingIndicator.Author property
• Ensure binding is established for ShowTypingIndicator

Suggestions not appearing:

• Bind Suggestions property to ViewModel
• Use IEnumerable type
• Update suggestions after bot responses

OpenAI connection issues:

• Verify API key is valid and not expired
• Check API endpoint URL is correct
• Ensure Microsoft.SemanticKernel NuGet is installed
• Confirm network connectivity
