WiceGrid Examples

View helpers to access records on the current page and all pages

Method current_page_records sent to the grid object returns a list of all ActiveRecord objects currently displayed on the page.

Method all_pages_records returns a list of all ActiveRecord objects throughout all pages of the current selection. all_pages_records causes an additional SQL query to be executed and has to be used with care.

Both methods can be used after the grid definition only.
