    ResizableControl is an extender that attaches to any element on a web page and

    allows the user to resize that control with a handle that attaches to lower-right 

    corner of the control. The resize handle lets the user resize the element as 

    if it were a window. The appearance of the resize handle can be specified by the 

    page designer with a CSS style. The content within the element can use 

    CSS styles to automatically resize to fit the new dimensions. Alternatively, 

    ResizableControl exposes two events (onresizing and onresize) that the page 

    designer can attach custom script to in order to enable more complex layout logic.

    Element dimensions are preserved across postbacks to the server and "size"

     properties accessible on both the client and server can be used to enable 

     custom resize behaviors. ResizableControl can optionally limit the maximum and 

     minimum width and height of the target control so that resizing can be constrained 

     by the page author (for example, to limit scrolling to only the horizontal dimension).
