AIChatControl.ChatResponseProviderServiceKey Property

Associates the chat control with the specific AI service.

Namespace: DevExpress.AIIntegration.WinForms.Chat

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

NuGet Package: DevExpress.AIIntegration.WinForms.Chat

Declaration

C#

[DefaultValue(null)]
public string ChatResponseProviderServiceKey { get; set; }

VB.NET

<DefaultValue(Nothing)>
Public Property ChatResponseProviderServiceKey As String

Property Value

Type	Default	Description
String	null	The unique identifier of the IChatResponseProvider service.

Remarks

Use the ChatResponseProviderServiceKey property to dynamically bind the DevExpress WinForms AI Chat Control to a specific AI service at runtime. You can allow users to choose an AI model or programmatically select the most appropriate model for a task. For example, use a powerful “thinking” model for complex queries and a faster, more cost-effective model for simpler interactions.

Example

The following example creates two chat controls and binds each control to its own AI service:

C#

using DevExpress.AIIntegration.WinForms.Chat;

AIChatControl azureChat = new AIChatControl() {
    ChatResponseProviderServiceKey = "azureAiProviderServiceKey",
    Dock = DockStyle.Right
};
AIChatControl ollamaChat = new AIChatControl() {
    ChatResponseProviderServiceKey = "ollamaAiProviderServiceKey",
    Dock = DockStyle.Left
};
this.Controls.AddRange(new Control[] { azureChat, ollamaChat });

VB.NET

Imports DevExpress.AIIntegration.WinForms.Chat

Dim azureChat As New AIChatControl() With {
    .ChatResponseProviderServiceKey = "azureAiProviderServiceKey",
    .Dock = DockStyle.Right
}
Dim ollamaChat As New AIChatControl() With {
    .ChatResponseProviderServiceKey = "ollamaAiProviderServiceKey",
    .Dock = DockStyle.Left
}
Me.Controls.AddRange(New Control() { azureChat, ollamaChat })
