TPanel acts as a presentational container for other control. It displays a <div> element on a page. The property Wrap specifies whether the panel's body content should wrap or not, while HorizontalAlign governs how the content is aligned horizontally and Direction indicates the content direction (left to right or right to left). You can set BackImageUrl to give a background image to the panel, and you can set GroupingText so that the panel is displayed as a field set with a legend text. Finally, you can specify a default button to be fired when users press 'return' key within the panel by setting the DefaultButton property.
