Other Standard Controls
This section briefly discusses the remainder of the controls in the Standard category of the Toolbox.You see many of them used in the sample application in the rest of the book.
LinkButton and ImageButton
The LinkButton and the ImageButton controls operate similarly to an ordinary Button control.
Both of them cause a postback to the server when they are clicked. The LinkButton presents itself as a simple element, but posts back (using JavaScript) instead of requesting a new page. The ImageButton does the same, but displays an image that the user can click to trigger thepostback.
Image and ImageMap
These controls are pretty similar in that they display an image in the browser. The ImageMap enables
you to define hotspots on the image that, when clicked, either cause a postback to the server or navigate
to a different page.
Calendar
The Calendar control presents a rich interface that enables a user to select a date. You see more of it toward the end of this chapter when the ASP.NET state engine is discussed.
