MessageSendingEventArgs.Contexts Property

Returns the collection of AI resources and files attached to the chat message.

Namespace: DevExpress.AIIntegration.Blazor.Chat

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

Declaration

public List<IAIChatMessageContextItem> Contexts { get; }

Property Value

Type	Description
List<IAIChatMessageContextItem>	The collection of resources.

Remarks

Use the Contexts property to access the collection of AI resources and files attached to the chat message.

Note

The Contexts collection is populated only when a user explicitly attaches resources or files to a message. Subsequent messages can access previously provided contexts from the chat history, but their Contexts collection remains empty.

The following code snippet logs each resource attached to the message:

<DxAIChat MessageSending="OnMessageSending"
          FileUploadEnabled="true" />

@code {
    private async Task OnMessageSending(MessageSendingEventArgs args) {
        if(args.Contexts != null) {
            foreach(var resource in args.Contexts)
                Console.WriteLine($"Resource: {resource.Name}");
        }
    }
}
