This sample demonstrates the frequent updates that occur in random cells across the Grid Grouping Control while keeping CPU usage to a minimum level.
Features:
A timer changes cells in short intervals and inserts and removes rows.
Features the implementation of very simple summaries that can be updated by applying a delta between old and new values when a record is changed.
This allows even faster updates for specific summaries.
When you run the sample, you should also open the task manager in order to see CPU usage. You should be able to start multiple instances without slowing down your machine.
