The event is triggered individually for each feature that is deleted. Is there any way I can know how many features are deleted together (say, user chose 10 feature on ArcMap and click "Delete"). I want to let the event handler behave differently when people choose different number of features to delete.</SPAN><BR /><SPAN>&nbsp;&nbsp; Thank you!</SPAN></BODY></HTML> Wed, 06 Nov 2013 21:03:38 GMT https://community.esri.com/t5/arcobjects-sdk-questions/how-to-know-the-number-of-features-being-deleted/m-p/435176#M11785 SuiHuang 2013-11-06T21:03:38Z Re: How to know the number of features being deleted together in an event handler? https://community.esri.com/t5/arcobjects-sdk-questions/how-to-know-the-number-of-features-being-deleted/m-p/435177#M11786 <HTML><HEAD></HEAD><BODY><SPAN>I've not tried this, so it may not work as you intend? </SPAN><BR /><BR /><SPAN>Why not listen out to the IEditEvents.OnSelectionChanged Event?

However, this is not always consistent with the number of feature being deleted.</SPAN><BR /><SPAN>&nbsp;&nbsp;&nbsp; For example, I can select 100 features, then open the Attribute Window, and then right click on one of the features in the Attribute Window and select "Delete".
