SharePoint 2013 Before and After Properties ALWAYS null

Question

I'm unable to get properties.AfterProperties and properties.BeforeProperties.

 public override void ItemUpdating(SPItemEventProperties properties)
    {
        Validate(properties);
        base.ItemUpdating(properties);
        Validate(properties);
    }

I've tried on ItemUpdated and ItemUpdating.

I can get to "Before" by using the SPItem, but I can't get the AfterProperties or "New Values"

The ONLY place I can find "New Values" is in VS2013 debug:

• properties {Microsoft.SharePoint.SPItemEventProperties} + base {Microsoft.SharePoint.SPItemEventProperties}

• AfterProperties {Microsoft.SharePoint.SPItemEventDataCollection} + ChangedProperties Count = 0 System.Collections.Hashtable

• Results View Expanding the Results View will enumerate the IEnumerable

[0] {System.Collections.DictionaryEntry} Key "vti_title" object {string} Value "xx" object {string}

I've changed the Synchronization to Sync and Async with no change.

I have code from SharePoint 2010 that works, but doesn't work in 2013.

Both the AfterUrl and BeforeUrl are retrievable.

Answer 1

BeforeProperties have values only ItemUpdating and ItemUpdated for Document library (not for lists).

AfterProperties have values only if you really change the value for that fields. If you don't, you'll obtain a collection of 0 items.

Have you changed the Elements.xml file, while changing ItemUpdated / ItemUpdating in your code?

Hope this help..
