You can configure a string constant, control, or indicator so that the control updates the block diagram as the user enters characters instead of waiting until the user presses Enter. Use this option to check the correctness of the input or to provide user feedback.

Update Value while Typing is disabled by default.

Toggle the setting to update while typing either interactively or programmatically.
  • Interactive: Right-click a string constant, control, or indicator and select Update Value while Typing.
  • Programmatic: Use the Update While Typing? property.
