'Declaration Public Sub ResumeSummaryUpdates( _ ByVal recalculateSummaries As Boolean _ )
public void ResumeSummaryUpdates( bool recalculateSummaries )
SuspendSummaryUpdates and ResumeSummaryUpdates methods can be used to temporarily prevent the UltraGrid from responding to cell change notifications and marking the summaries dirty. Summaries are re-calculated lazily however this method is useful when you are modifying a lots of cells and for efficiency reasons you want to prevent UltraGrid from responding to every cell change notification. In that case you can call SuspendSummaryUpdates and change the cell values and call ResumeSummaryUpdates. ResumeSummaryUpdates method takes in recalculateSummaries parameter that you can use to specify whether the UltraGrid should recalculate all the summaries or not. You would specify that parameter as false if you know that none of the changes you made affected the summaries. Otherwise you would specifiy that parameter as true.
