Displaying a Message in Response to Some Action and Then Hiding It on Subsequent Postbacks

(Scott Mitchell) ASP.NET web pages commonly display messages in response to user actions. For instance, a typical CRUD (Create, Read, Update, Delete) web page might display the message, "Record deleted" immediately after deleting a record and the message "Record updated" immediately after updating a record. Likewise, there would be messages displayed for inserting a new record and messages displayed in the event of an error. Such messages are typically displayed using a single Label Web control. This control may be located at the top of the page and have its Text property initially set to empty string. Then, when particular events transpire, the Label's Text property is updated accordingly.
