Interface IResponseBlock

Represents a response block that can be rendered within the SfAIAssistView component.

Namespace: Syncfusion.Blazor.InteractiveChat

Assembly: Syncfusion.Blazor.InteractiveChat.dll

Syntax

public interface IResponseBlock

Remarks

The IResponseBlock interface serves as the base contract for all AI response block types displayed in the AI AssistView conversation. Implementations define the structure and metadata required to render specific content such as text, reasoning traces, charts, grids, weather cards, and other generative UI elements.

The rendering behavior of a response block is determined by the value of the BlockType property. The AI AssistView uses this value to resolve the appropriate UI template and presentation logic for the response.

Built-in implementations typically include text-based responses, thinking/reasoning blocks, and tool-based blocks that can host custom interactive UI elements.

Examples

The following example demonstrates creating a text response block:

List<IResponseBlock> responseBlocks = new()
{
    new TextBlock
    {
        BlockType = BlockType.Text
        Content = "Hello! How can I assist you today?"
    }
};

await aiAssistView.UpdateResponseAsync(string.Empty, responseBlocks);

Properties

BlockType

Gets the type of the response block.

Declaration

BlockType BlockType { get; }

Property Value

Type	Description
BlockType	A BlockType value that identifies the category of content represented by the current response block. No default value is defined by the interface and must be provided by the implementing type.

Remarks

This property is used by the SfAIAssistView component to determine how the response block should be rendered in the conversation view.

Implementations should return a valid and consistent BlockType value throughout the lifetime of the block instance.

Common block types include text content, reasoning or thinking content, and tool-driven generative UI content.
