The caretPosition is tied to the generated text, meaning it’s relative to the parsed string— it excludes rich text tags. The onValueChanged callback fires after the string is updated, but before the text generation. This timing supports custom validation and isn’t something we can change.

If you don’t need the parsed string (no rich text tags), I’d recommend using inputField.stringPosition instead. If rich text is involved, I’d recommend updating the caret on the next frame like this:

public class SetCaret : MonoBehaviour
{
private TMP_InputField inputField;
private void Start()
{
inputField = GetComponent<TMP_InputField>();
inputField.onValueChanged.AddListener(_ => StartCoroutine(DelayedCaretSet()));
}

private IEnumerator DelayedCaretSet()
{
yield return null; // Wait for next frame
inputField.caretPosition = inputField.stringPosition;
}
}
