DXGrid can operate on any in-memory IEnumerable data sources using Parallel LINQ (PLINQ), improving performance for data-intensive operations (e.g. sorting, grouping, filtering, summary calculation, etc.) by making full use of all the available processors/cores on the system.
To support Parallel LINQ, you should specify the source collection for a PLINQ data source and bind it to the grid. The source collection must implement IEnumerable<T>. You should not provide the exact type of its elements, because the type is automatically evaluated at runtime.
When using PLinqInstantFeedbackDataSource, the source collection can be dynamically populated by the IListSource.GetList() method or within the PLinqInstantFeedbackDataSource.GetEnumerable event handler. Data objects are loaded in a separate thread, allowing you to perform time-consuming operations (e.g. dynamically create large volumes of data) without UI freezing. In these instances, you need to ensure thread safety yourself.
