Server-Side Pagination, Sort, Filter

Data in this demo is loaded on demand when you change Page, Sort, Filter or expand a Group. This is achieved by using the Grid's Data Virtualization in combination with DataAdapter's "virtualDataSource".

• Paging is enabled by setting the pager: { visible: true } and paging: { enabled: true } properties.
• Filtering is enabled by setting the filtering: { enabled: true } property.
• Sorting is enabled by setting the sorting: { enabled: true } property.
• The number of rows returned per request is set to 10, which is equal to the pageSize.
• The 'first' and 'last' properties in the data request are used by the server to perform paging.
• The 'query' in the data request is used by the server to perform sorting and filtering.
