UseId(string?)

Returns a stable unique ID string tied to the component instance and slot position. Re-renders of the same component return the same ID; different instances or different slots receive different IDs. Use as a unique key for label-to-field association or aria attributes.

public static string UseId(string? prefix = null)

Parameters

prefix string

Optional prefix to prepend (omitted when null/empty). Only the first render reflects this in the generated ID; changes on subsequent renders are ignored (same convention as the initial value of UseState).

Returns

string

Format is :r{hex}: (no prefix) or {prefix}:r{hex}: (with prefix).
