Essential Grouping

Essential Grouping allows users to group data, access filtered results and have summary information without the overhead of graphical display code. The Grouping Engine extracts all the data manipulation, handles the data and gives users ways to access the needed results.

The Grouping Engine	UI Independent
How it works

Responsive to Data Changes

If a data source supports IBindingList/ListChanged events, then Essential Grouping listens to these events, responding appropriately. If the datasource does not support IBindingList, the Grouping Engine may refresh itself as appropriate.

Editing Items	Adding New Items
Deleting Items

Sorting

Essential Grouping supports multikey sorting without relying on ADO.NET. It will sort any IList data source.

Multikey sorting	Supports IComparer
Sorting Respects Groups
