Below are shown the results only for the events that have this problem.
Note: - The list I am attaching this to does NOT have version history turned on. So the question is: What is a good technique that can be implemented such that I can check whether a specific column in a list changed in the The blog post James's colleague wrote is wrong.

And where it reallygets tough, it also depends on the type of list, whether the current list is a list or library.During these actions, we can know the field values and sometimes the previous value of the field. Given this number of possibilities a little summary table seemed necessary, here it is.For this we must add the synchronization parameter to our xml definition.
object will be used for both the updating and updated events, and that instance won't be reused in the context of a separate update.
This will allow us to pre-fill the data in our forms before the user does not grasp anything!

Ok, so inside the Item Updating, you might use the following code: This may seem fine, but if the tested column wasn't filled in it's not part of the After Properties collection, and trying .
