How to access added item values of List Item in ItemAdded event handlers into SharePoint

 

 Code:

 

 

public override void ItemAdded(SPItemEventProperties properties)

        {

            base.ItemAdded(properties);

            string strTitle = string.Empty;

           using (SPSite site = new SPSite(properties.WebUrl))

           {

           using (SPWeb web = site.OpenWeb())

           {

           SPList list = web.Lists[properties.ListTitle ];

           SPListItem item = list.GetItemByIdSelectedFields(properties.ListItemId, "Title");

           strTitle = (String)item.DisplayName ;

            }

            }

 

Working with BeforeProperties and AfterProperties on SPItemEventReceiver

Here are the results for a list:

List	BeforeProperties	AfterProperties	properties.ListItem
ItemAdding	No value	New value	Null
ItemAdded	No value	New value	New value
ItemUpdating	No value	Changed value	Original value
ItemUpdated	No value	Changed value	Changed value
ItemDeleting	No value	No value	Original value
ItemDeleted	No value	No value	Null

No value means that column value in the hash table was not available. 
New value means that the correct value for the column was available. 
Changed value means that the correct updated value was available.
Original value means that the correct original value was available.

Here is the same test against a document library:

Library	BeforeProperties	AfterProperties	properties.ListItem
ItemAdding	No value	No value	Null
ItemAdded	No value	No value	New value
ItemUpdating	Original value	Changed value	Original value
ItemUpdated	Original value	Changed value	Changed value
ItemDeleting	No value	No value	Original value
ItemDeleted	No value	No value	Null

Properties.ListItem refers the the current value for the list item at that point in the event.  Null means that the item is not available.  My analysis yields the following results:

• Not surprisingly, we get null values for for ItemAdding (before item is added) and ItemDeleted (after item is deleted). 
• As correctly documented in the SDK, item events for lists do not expose BeforeProperties.
• ItemAdding and ItemAdded correctly report the value in the AfterProperties for an list item, but not a library item.  This is curious.
