EndUpdate Method

Restores painting and events to the state they were in before the last call to BeginUpdate, releases the lock acquired by BeginUpdate, and starts background calculation if appropriate.

[Visual Basic]
Overridable Sub EndUpdate()

[C#]
virtual void EndUpdate();

[C++]
virtual void EndUpdate();

[C++/CLI]
virtual void EndUpdate();

Remarks

This method is thread safe.

EndUpdate releases the lock which was acquired by BeginUpdate by calling GetLock.

See GetLock and ReleaseLock for more information about acquiring and releasing locks and the effect this has on background calculation.

Example

[C#] Demonstrate using a workbook set in a thread safe manner when accessing the SpreadsheetGear API many times.

void DoSomeThreadSafeWorkQuickly(IWorkbookSet workbookSet) 
        { 
            // Interrupt background calculation if necessary, acquire an 
            // exclusive lock on the workbook set and suspend events and 
            // painting. 
            workbookSet.BeginUpdate(); 
  
            try { 
                // Do a lot of work... 
            } 
            finally { 
                // Release the lock on the workbook set, start background 
                // calculation if appropriate and repaint controls. 
                workbookSet.EndUpdate(); 
            } 
        }
