Fires after the AI provider returns a response, before the chat displays the message.

Namespace: DevExpress.AIIntegration.WinForms.Chat

Assembly: DevExpress.AIIntegration.WinForms.Chat.v26.1.dll

NuGet Package: DevExpress.AIIntegration.WinForms.Chat

Declaration

C#

[DXCategory("Events")]
public event EventHandler<AIChatControlResponseReceivedEventArgs> ResponseReceived

VB.NET

<DXCategory("Events")>
Public Event ResponseReceived As EventHandler(Of AIChatControlResponseReceivedEventArgs)

Event Data

The ResponseReceived event's data class is DevExpress.AIIntegration.Blazor.Chat.WebView.AIChatControlResponseReceivedEventArgs.

Remarks

Handle the ResponseReceived event to inspect or modify AI responses after the provider returns them. This event is useful for logging, filtering, and post-processing multi-part responses. You can also use the event to modify metadata about invoked tools or functions before the chat UI displays the response.

Example

The following example outputs the text of every received message:

C#

using DevExpress.AIIntegration.Blazor.Chat.WebView;

public Chat() {
    InitializeComponent();
    aiChatControl1.ResponseReceived += AiChatControl1_ResponseReceived;
}

void AiChatControl1_ResponseReceived(object sender, AIChatControlResponseReceivedEventArgs e) {
    foreach (var message in e.Messages) {
        Console.WriteLine(message.Text);
    }
}

VB.NET

Imports DevExpress.AIIntegration.Blazor.Chat.WebView

Public Sub New()
    InitializeComponent()
    AddHandler aiChatControl1.ResponseReceived, AddressOf AiChatControl1_ResponseReceived
End Sub

Private Sub AiChatControl1_ResponseReceived(sender As Object, e As AIChatControlResponseReceivedEventArgs)
    For Each message In e.Messages
        Console.WriteLine(message.Text)
    Next
End Sub
