EnableEvents Method

Summary

Enables raising the Changed event.

Syntax

Java

Objective-C

WinRT C#

C++

public void EnableEvents()

Public Sub EnableEvents()

public void EnableEvents()

-(void)enableEvents

public void enableEvents()

 function Leadtools.RasterImage.EnableEvents()

public: 
void EnableEvents();

Remarks

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.

Example

For an example, refer to Changed.
