How to: Customize Calendar Web Server Control Appearance
Because the Calendar control is a complex control made up of many individual elements, it offers you a wide variety of options for customizing its appearance.
Changing General Calendar Appearance
The Calendar control establishes a default look for the calendar on the page, but you can change the calendar's overall appearance. If you set appearance properties for individual calendar elements, such as today's date, the selected date, and so on, the individual settings are based on the default settings you make for the calendar as a whole. You can also select from predefined formats.
Note
By default, there is no special formatting to indicate today's date on the Calendar control. For details about how to set this format, see Formatting Web Calendar Elements Using Styles.
