Itemupdating not

This is true for Share Point 2010 and Share Point 2013 and its present only for custom lists but not for document libraries.

To work around this issue, I implemented the following code: The code looks for the key (the Doc ID) in the property bag and if it is present, skip the creation of the task and remove the property from the bag.A general software development principle is to suspend or temporarily disable events from firing that you may trigger unintentionally from your code.It is particularly difficult to do this yourself in an event receiver in Share Point because you typically don’t have any context to work with.These events could be web events (Web Adding, Web Provisioned, Web Deleting etc), feature events (Feature Activated, Feature Deactivated etc) or most popularly, list item events (Item Updated, Item Updating, Item Added etc).Before Properties and After Properties are available for the different event receiver classes.
