Introduction to Balloonpopup Controls

The Balloonpopup control can display a pop-up layer, which can contain a lot of content. For example, when a user moves the mouse over a text box, you can use this control to display some help information for the user.

The Balloonpopup control supports three styles (Balloonstyle): Balloon Style (Balloon), rectangular style (Rectangle), and user-defined styles (custom). The size of the pop-up layer also has three models: Small (Small), Medium (Medium), Large (Large). If you set the Balloonstyle attribute to custom, you need to set the Customcssurl property value to the path of the custom style sheet.
