I am using Sitecore 7.0. Visual Studio 2013. I want to create an item's child in Sitecore using event Handler. So whenever an item is created, its child automatically added. For this I wrote an eventHandler on "item:added" event.
But I am getting NullReferenceException exception "Exception Details: System.NullReferenceException: Object reference not set to an instance of an object."
I figure out that Database.GetItem() method is not working in Sitecore Events.
Item entryFolderItem = Sitecore.Context.Database.GetItem("/sitecore/content/Site Config/Configuration/Entry Folders Structure");
The above item exist in sitecore and I have also tried with ID. But still I get the same error.
I also tried the same code on event item:saved but still I get the same error.
Any suggestion for this problem!!
By the way here you can find a nice article on events.
Don't assume you can get a context. Besides, going for context database would be wrong, so would be going for a hardcoded "master" database.
When you extract the Item from EventArgs, use the .Database definition from there to perform your operations.
Item eventItem = eventArgs.Parameters[0] as Item;
Database db = eventItem.Database;
