Handler itemupdating

I've created an event receiver to handle the ItemAdded and ItemUpdating events on a document library in SharePoint 2010. I've encountered a problem where when I add a document to the library (e.g. by saving it back from Word) the ItemAdded method is correctly called however this is then followed by two calls to ItemUpdating. This is to summarize the inconsistent behaviors I encountered when working with 'AfterProperties' in 'ItemUpdating' event handler on a custom SharePoint list in SP 2010. 1) AfterProperties will be NULL when ItemUpdating event is called because of a code-update to list: Home > Event handler types, ItemAdding and ItemUpdating, Sharepoint, Sharepoint Event Handler Example, ... How to access fields of List Item in ItemAdding and ItemUpdating event handlers into SharePoint. June 23, 2009 dishashah08. Welcome Reader, I have moved to a new blog site, so you can get same content from below new site URL!! ... You could check the BeforeProperties, ListItem and AfterPropertiesin your ItemUpdating event receiver to check if there is updates being made that you have to take action on. If not, then just return. Here is a guide for when you can use .BeforePropertiesand when you should go in the .ListItem instead. SharePoint List Event Handler Types and Working with AfterProperties and BeforeProperties Scenario: I was having the requirement to execute my custom code when a SharePoint ListItem is updated. This custom code should write some of the updated field values to database. Developing a Sharepoint application would have all the fun of a video game, if only you had infinite lives. Dangers lurk hidden out there which, if you run into them, can be a blow to your project and waste a great deal of time. Damon gives just one example of a poisoned dagger in the game of Sharepoint Development: The Item Event Receiver. I was disabling the event firing on an itemupdating handler, but this handler writes data to another list, that list has workflow associated with it (fires on item create) and it was NOT firing… I had to set EventFiringEnabled = true just before the call to write to the second list, then set it back to its previous value… I was recently developing a list item Event Receiver, implementing the ItemAdded and ItemUpdating events.. The purpose of this event receiver is to populate fields of items of a particular content type, and the fields in question are hidden from the user by setting the ShowInNewForm and ShowInEditForm properties of the FieldRef elements when the fields are provisioned in a content type, as ... In addition to trapping standard list item events (for example, ItemAdding, ItemDeleting, or ItemUpdating), you can trap schema events (such as adding, removing, or updating columns), as well as Web site and site collection deletion. Creating a Basic Event Handler I think, I found the easiest way to check if a particular field was changed inside ItemUpdated handler. Here is what you should do: Add a new hidden field to the list. Register a new EventReceiver for ItemUpdating. It will save previous field values.

Odd Event Reciever behavior

2019.12.11 01:37 StaleCornflake Odd Event Reciever behavior

On prem 2013 Enterprise. We use Nintex 2013. We have an event receiver that uses itemAdded, itemUpdated and ItemDeleted. This stopped working in our QA environment and was resolved by restarting the C2WTS. Now in production, the same thing is happening but recycling the service doesn't resolve it. Here is the odd behavior. While it doesn't fire on item added it does run when the workflow is run manually. The first time the WF runs, or in this case fails to run, the item is being added by input from a third party external app (not a hosted app) that is on our network.
Has anyone encountered this behavior with an event receiver? Thoughts? Logging in the Event Handler shows it isn't firing as there is nothing being submitted to those logs.
