The UXDataPager control provides a configurable user interface for paging through a data collection. Similar to the other ClientUI data controls, UXDataPager supports both server side and client side operation.
Client data operation means that the data operation, in this case data paging, is executed in the client side against the data source provided to the UXDataPager. To use this operation, you set the QueryOperation property to Client.
You typically use a collection that implements IPagedCollectionView as the data source. The IPagedCollectionView provides paging support to the underlying collection. You can bind the UXDataPager to any IEnumerable collection; however, the UXDataPager will behave as if the data is all on a single page. To provide paging functionality for an IEnumerable collection, you can wrap the collection in a PagedCollectionView instance.
Server data operation means that data operation in this case data paging is processed in the server. This means that UXDataPager does not handle the paging operation by its own. Instead, UXDataPager provides the query information allowing you to process it further.
To use this mode, you set the QueryOperation property to Server. When this mode is selected, UXDataPager will not attempt to perform the data operation on the given data source. Instead, it will store and distribute the query information on certain properties such as PageIndex, PageSize and TotalItemCount which are defined in the PageDescriptor property. When one of these properties change, the QueryChanged event of the associated QueryDescriptor will be raised. This allows you to streamline the query processing in a centralized function, which is one of the strong benefits of QueryDescriptor. For more information about QueryDescriptor, see QueryDescriptor Overview.
