Description
Occurs when the focus leaves the memo or the user presses ENTER. The event occurs only when the text has changed.
OnChange is raised when the following situations occur:
- Text is cleared in the memo.
- Text is set in the memo.
- The memo loses focus.
- The user presses the ENTER key.
Write an OnChange event handler to check the modified text data.
