Pass Through Grouping

Pass Through grouping is a great way to take control of data being retrieved from the datasource. The default setting of the GridControl pull all records from the underlying datasource to perform grouping and calculation of summaries.

However, you can override this behavior using "Pass Through Grouping" and retrieve only required records from the datasource. Even when the grid is bound to millions of records Pass Through grouping will retrieve only group information from the datasource. Records of a specific group will be retrieved on-demand as users expand groups.

Pass Through grouping can be implemented against any datasource using any data retrieval technique. The most ideal data retirieval techniques is LINQ, which is elaborated in the next section.
