Start Formview itemupdating not firing

Formview itemupdating not firing

Sometimes that is the most exciting way to learn, but for those less adventurous I will briefly cover the topic here.

With that in mind, Share Point 2010 is like a sea of icebergs – there is a lot going on under the surface that you may not notice until it’s too late.

Unfortunately, that makes your project like the Titanic.

I can't for the life of me figure out when On Item Updated gets fired. NET trying to learn it, so some of the things you see in this code might be purposely done the hard way (so I can better understand whats going on behind the scenes) Basically, I have a Grid View that is the master control that uses a formview as a detail. I thought I understood that the button would call Command="Update" which would fire Item Updating and then Item Updated.

Am I missing a step somewhere to get this event to fire?

Damon gives just one example of a poisoned dagger in the game of Sharepoint Development: The Item Event Receiver.

I’m usually disappointed when writers employ oft-overused metaphors to describe a situation.

For example, if you define an instance level variable in the class to store data in the Item Updating event, then try to access that data in the Item Updated event, you will find that the data is not there when you go to check it in the Item Updated event.

This is because you have two classes – one that is handling the Item Updating event and in which the instance level variable is set, and one that is handling the Item Updated event in which the instance level variable is not set.

I'm not using datasource controls, so I have to do more of the plumbing myself.

Do I have to call the Change Mode() method in the Mode Changing event handler? I can see the mode in the process of changing, because my Mode Changing handler gets called, but then the Mode Changed handler never gets called.

Item Event Receivers derive from the SPItem Event Receiver class and have a number of methods that can be overridden to respond to various events: As you look through this list, you should notice that events have two types of endings: WARNING: One major gotcha you should know about the SPItem Event Receiver class is that while you can implement multiple list item event handlers in a single class, Share Point instantiates a new instance of that class for each individual event it needs to handle.
