Pagination

Pagination

In contrast to the OnDemandList and OnDemandGrid modules, the Pagination extension implements classic discrete paging controls. It displays a certain number of results at a given time, and provides a footer area with controls to switch between pages.

require([
	"dojo/_base/declare", "dgrid/Grid", "dgrid/extensions/Pagination"
], function(declare, Grid, Pagination){
	var grid = new (declare([Grid, Pagination]))({
		store: myStore,
		columns: myColumns,
		pagingLinks: 1,
		pagingTextBox: true,
		firstLastArrows: true,
		pageSizeOptions: [10, 15, 25]
	}, "grid");
	// ...
});

Note: the Pagination extension should be mixed into List or Grid, not one of the OnDemand constructors, since those contain their own virtual scrolling logic. Internally, Pagination inherits from the same _StoreMixin module inherited by the OnDemand prototypes for common integration with dojo/store.

API

The Pagination extension supports the following additional instance properties and methods.

In addition, the Pagination extension also inherits properties and methods supported by dgrid/_StoreMixin; for details, see the tables for properties and methods inherited from _StoreMixin in the documentation for OnDemandList and OnDemandGrid.

Property Summary

Property	Description
rowsPerPage	Number of items to show on a given page. Default: 10
previousNextArrows	Whether to show arrows which go to the previous/next pages when clicked. Default: true
firstLastArrows	Whether to show arrows which jump to the first/last pages when clicked. Default: false
pagingLinks	If a positive number is specified, renders a sequence of page numbers around the current page, and for the first and last pages. The number specified indicates how many "neighbors" of the current page are rendered in each direction. If 0 is specified, no page number sequence is rendered. Default: 2
pagingTextBox	Whether to show a textbox in place of the current page indicator, to allow immediately jumping to a specific page. Default: false
pageSizeOptions	An optional array specifying choices to present for the rowsPerPage property in a drop-down. If unspecified or empty, no drop-down is displayed.

Method Summary

Method	Description
gotoPage	Loads the indicated page. Note: Page numbers start at 1.

Events

Like OnDemandList, the Pagination extension will emit a dgrid-error event for any error which occurs while attempting to query the store in response to user interaction.

Internationalization

The Pagination extension retrieves the strings for various parts of its UI from resources in dgrid/extensions/nls, via the dojo/i18n! plugin. These strings are stored in an i18nPagination property on the grid instance, and can be overridden if desired. The optimal point in the lifecycle to override any i18n strings would be in postMixInProperties, or in buildRendering before calling this.inherited(arguments).
