When an event message is transmitted to the server, it checks whether the Click event has an associated event handler, and if it has, the event handler is executed.

Request Object Instance of the class. 6 Over View Response Object The Response object represents the server's response to the client request. Instance of class. 7 TODAY’S LESSON Contents - Server Controls Web Controls Properties of Server Controls Methods of Server Controls - HTML Server Controls - HTML Client Side Client Side Scripts Client Side Source Code - Basic Controls 9 Server Controls Controls are small building blocks of the graphical user interface, which includes Text boxes Buttons Check boxes List boxes Labels and numerous other tools. Using these control users can enter data, make selections and indicate their preferences. 10 Server Controls Controls are also used for structural jobs like Validation Data Access Security Creating master pages Data manipulation 11 Server Controls. uses 5 types of web controls HTML controls HTML Server controls Server controls Ajax Server controls User .
