ResumeNotificationProcessing Method

Resumes notification processing after a preceding call to SuspendNotificationProcessing.

Syntax

Visual Basic

'Declaration
 
Public Sub ResumeNotificationProcessing( _
   ByVal dirtyAllFormulas As Boolean _
) 

C#

public void ResumeNotificationProcessing( 
   bool dirtyAllFormulas
)

Parameters

dirtyAllFormulas

Specify true to dirty all formulas so they will all be recalculated.

Example

SuspendNotificationProcessing and ResumeNotificationProcessing can be used to temporarily suspend UltraCalcManager from processing value change notifications. Typical reason for doing this is for better efficiency. Every cell value change will cause a notification to be sent to the UltraCalcManager which in turn will process the notification. When a lot of values need to be changed in an UltraGrid for example, you can use these two methods to suspend this notification processing. ResumeNotificationProcessing method takes in a dirtyAllFormulas parameter. Passing in true here will cause all the formulas to be recalculated. You can pass in true or false based on whether you are modifying cells that are used as source of values in formulas or not. For example if you know that you are modifying cell values of a column that is not used in any formulas then you can pass false for the dirtyAllFormulas.
