| Leadtools Namespace > RasterImage Class : DisableEvents Method |
public void DisableEvents()
'Declaration
Public Sub DisableEvents()
'Usage
Dim instance As RasterImage instance.DisableEvents()
public void DisableEvents()
- (void)disableEvents
public void disableEvents()
function Leadtools.RasterImage.DisableEvents()
public: void DisableEvents();
Calling DisableEvents will increment an internal counter. When the internal counter is 0, the Changed events will be raised for changes to the RasterImage.
When the internal counter is != 0, Changed will not be raised. Therefore, for each call to DisableEvents, there should be a corresponding call to EnableEvents in order to restore the raising of events.
You can temporary disable the Changed event when performing multiple operations on a RasterImage object then re-enabling it once the operations are done. This way, any listeners to the Changed event will be notified only once thus optimizing the performance.
