Syncfusion Essential Grouping is a data technology that allows you to easily access, manipulate and display your data in a variety of configurations. Your data source can be any IList object whose items have public properties. You can easily sort the items on one or several of these public properties; you can display and retrieve items based on the grouping that is produced through these sorts; you can include caption information or summary information on these groups; you can impose filters on the items, retrieving only items that specify your filter conditions, and you can also add expression properties to display calculated values depending upon other properties in the item. Grouping also supports nested tables and hierarchies in the form of related tables.
