An Aside Control is a simple container control that is rendered using an <aside> HTML tag. Its primary purpose is to act as a container for other controls which can be laid out according to the selected layout – click here for a general discussion on container controls and layouts.
An Aside Control is functionally identical to a Panel Control and inherits all its properties and behaviour. The only difference is that it uses <aside> instead of <div> as the enclosing HTML tag.
The HTML <aside> element represents a portion of a document whose content is only indirectly related to the document's main content. Asides are frequently presented as sidebars or call-out boxes. Aside Controls map automatically to the complentary ARIA role so there is no need to explicitly provide an ARIA role unless you want to change this.
