How to place aggregates on top of the Grid

By default, the aggregated values are placed at the bottom of the footer section. It is possible to place the aggregated values at the top of the header. This is achieved by using the dataBound event, getHeaderContent, and getFooterContent methods of the Grid.

In the following sample, the footer element is appended to the header element using the getHeaderContent and getFooterContent methods in the dataBound event.
