Refresh Data
The ExpressPivotGrid control is automatically updated when the bound data source is modified (for instance, when records are added, deleted or changed). Since the control’s data controller caches the data from the data source, you need to update the control manually only when its data is modified either via a field’s Values property or the pivot grid’s DataController.Values property. In this instance, call the FullRefresh method which will forcedly reload the records from the data source and recalculate all summaries.
