The Grid component supports data paging. You can specify the page size and switch pages programmatically or via the Paging Panel's UI controls. The paging state management, Paging Panel rendering, and built-in paging logic are implemented in the corresponding plugins. You can also configure the Grid to use server-side paging if your data service supports it.
The following plugins implement filtering features:
Note that the plugin order is important.
Use the PagingState, IntegratedPaging (or CustomPaging), and PagingPanel plugins to set up a Grid with paging.
In uncontrolled mode, specify the initial active page index in the PagingState plugin's defaultCurrentPage property.
In the following example, the page size is specified using the PagingState plugin's pageSize property, which is usual for the controlled mode. However, the onPageSizeChange event handler is not specified because the page size is not supposed to be changed internally as the Page Size Selector is not available.
Assign an array of available page sizes to the PagingPanel plugin's pageSizes property to enable page size selection via the UI. The Page Size Selector displays the 'All' item if the specified array contains an item whose value is 0. You can specify custom text for this Page Size Selector item using the messages.showAll property.
The example below demonstrates a basic configuration for the uncontrolled mode. The PagingState plugin's defaultPageSize property defines the initial page size.
In controlled mode, specify the following PagingState plugin property pairs to set a state value and handle its changes:
currentPage and onCurrentPageChange - the currently displayed page's indexpageSize and onPageSizeChange - the page sizeNote that the onPageSizeChange handler makes sense only if the pageSizes option is specified. Otherwise, a user is not able to change the page size.
You can handle the Grid's paging state changes to request page data from the server according to the current page index and the page size if your data service supports paging.
Paging options are updated once an end-user interacts with Paging Panel controls. Handle paging option changes using the PagingState plugin's onCurrentPageChange and onPageSizeChange events, and request data from the server using the applied paging options. Once the page data is received from the server, pass it to the Grid component's rows property.
For remote paging, use the CustomPaging plugin instead of the IntegratedPaging plugin.
When you use paging features with sorting, grouping, or filtering, take note of the order in which the plugins appear in the Grid's container. You need to choose whether to paginate filtered rows or filter the current page. In the former case, put the IntegratedFiltering plugin before the IntegratedPaging one. Otherwise, inverse the plugins' order.
