Event

WebTextArea.TextChanged()

Supported for all project types and targets.

Unlike the desktop, this event does not fire with each change to text. Instead it fires only when the text has changed and the user either pressed the Enter or Return keys or the control loses the focus. If you need to execute code on each keystroke, use the KeyUp event. The keys that trigger TextChanged depend on the browser. Note that this is not supported for WebLabel since the text can’t be changed by the user.
