Blazor LLM Kit Checkpoint

Updated on Aug 13, 2026

The Checkpoint component marks a recoverable point in an agent conversation. It lets users restart the workflow from that point without losing prior context. Use the component alongside AI-generated responses to give users a clear way to go back and try a different path.

Creating Blazor Checkpoint

To use the Checkpoint component:

1. Add the <TelerikCheckpoint> tag.
2. Set the State parameter to a CheckpointState value.
3. Subscribe to the OnClick event to handle the user action, for example resetting the workflow.
4. (optional) Set Visible="true" to keep the checkpoint always visible. Otherwise, it appears on hover.

<TelerikCheckpoint State="@CheckpointState"
                   Visible="true"
                   OnClick="@OnCheckpointClick" />
