Jui controls are the PRADO port of the standard jQuery UI widgets. They can be used as standard Active Controls, but will automatically load the needed jQuery-UI javascript libraries.
The Options property of PRADO Jui controls is used to pass options to the underlying javascript object. Each subproperty set on Options will be translated to a javascript property added to the object. The complete list of options available for each widget is availble at jQuery-UI's API Documentation.
jQuery-UI's Resizable adds an handle to a target element making it resizable. Its PRADO counterpart is TJuiResizable. Resizable offers an aspectRatio property to constrain the aspect ratio of the target element. The same property can be applied to TJuiResizable as a subproperty of the Options property:

Draggable exposes two useful events: start and stop, that gets triggered respectively when the element starts to move and when the movement stops. TJuiDraggable exposes these same events:
