The TextBlock class is the standard response block used to present textual information generated by an AI service or provided programmatically. Text blocks can be combined with other response block types, such as ThinkingBlock and ToolBlock, to create rich conversational experiences.

This block is rendered according to the text presentation settings of the SfAIAssistView component and supports content returned through UpdateResponseAsync.

The class is lightweight and intended for displaying content only. No additional processing or rendering overhead is introduced beyond standard text rendering.

Examples

The following example demonstrates how to create and display a text response block:

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

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

Constructors

TextBlock()

Declaration

public TextBlock()

Properties

BlockType

Gets or sets the type of the response block.

Declaration

public BlockType BlockType { get; set; }

Property Value

Type	Description
BlockType	A BlockType that identifies the block as a text response. The default value is Text.

Remarks

The AI AssistView uses this property to determine the appropriate rendering behavior for the block.

For instances of TextBlock, this property should typically remain set to Text.

Content

Gets or sets the textual content displayed by the response block.

Declaration

public string Content { get; set; }

Property Value

Type	Description
string	A string containing the text to render in the conversation. The default value is `string.Empty`.

Remarks

The content may include plain text or supported formatting syntax, depending on the configuration and rendering capabilities of the hosting SfAIAssistView.

If an empty string is provided, the block renders without visible text content.

Examples

var textBlock = new TextBlock
{
    Content = "The analysis has completed successfully."
};
