Show Password Button

Client-side API

RadTextBox provides a built-in ShowPasswordButton for password fields. When enabled, a toggle icon appears inside the input allowing users to reveal or hide the entered password. This demo shows the feature in a practical sign-in form scenario.

Key Features

  • ShowPasswordButton property — set to true to display the toggle icon. Only applies when TextMode is set to Password.
  • get_passwordVisible() / set_passwordVisible(value) — client-side methods for programmatic control of password visibility.
  • Accessibility — the toggle button has proper role="button" and aria-label attributes that update dynamically.
  • DefaultVB.aspx
  • DefaultVB.aspx.vb
  • styles.css
