If you wish to modify a property value on the list item during the event, the value should be updated in After Properties property of the properties parameter.Share Point reads these values from the event parameter and modifies the item accordingly when the actual operation runs (e.g.That means that if you register a event receiver Item Adding to your list, every time you add new item to your list, that event will trigger, and custom code that you put in your Event Receiver will be executed.

One major thing 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.

What this means is that you cannot store data in instance-level variables and share that data between event handlers.

Original value means that the correct original value was available.

So, if we go back to our original problem listed above.

As many of you know, event receivers are a great way to hook into various Share Point events.

These can apply to Feature events such as Feature Activated, List events such as Field Added, and many others.New value means that the correct value for the column was available.Changed value means that the correct updated value was available.So the net result of this is that the document is uploaded and the Item Adding and Item Added events have fired, which is pretty much what you would expect.Next, let’s look at what happens when the user adds a document when the Require Check Out option is enabled.The most common set of receivers used, however, are part of SPItem Event Receiver which let you wire your code up to a number of events that can occur to items on a list or library.When working with events, you’ll quickly find that before (synchronous) and after (asynchronous) events exist, and the method suffix such as “ing” (e.g. Item Added) will tell you whether it gets invoked before or after the actual change is made. And, as you get deeper, you’ll even find that you can extract the before and after state of the change.Declare the correlation token for the workflow in the On Workflow Activated activity.Then, for each activity that affects the entire workflow, bind that activity’s correlation token to the correlation token of the On Workflow Activated activity.How can we prevent a user from changing a certain column for an item in a list event?From the list table, you can see if we hook into the Item Updating event, we can compare the current item’s value (properties.
