I am looking for a solution where I can set the bit when field value changes in Item Updating.
Check this bit if set do the processing in Item Updated.
To prevent users from changing the name of the planet, you can develop a Item Updating event receiver.
This event occurs before the data is saved to the Share Point list.
SPItem Event Receiver has a property called Event Firing Enabled, which simply indicates whether event firing is enabled.
We can turn this off to prevent our loop from occuring.
Now you may ask, why not just set it to false in the constructor and set it to true in the Dispose.You could think that the current values are stored in the Before Properties of the item but that’s not true: the Before Properties are unreliable at this point. When the name of the planet is changed, the update is canceled and an error message is returned to the user.If the name isn’t changed, the changes are saved to the Share Point list.For 5 successive years I’ve been rewarded as Share Point Server MVP for my contribution to the Share Point community: I developed the U2U CAML Query Builder and its successor the CAML Designer, which I develop together with Andy Van Steenbergen.In the many years I worked for U2U, I worked as technical assistant for Patrick Tisseghem who unfortunately died on 3th September 2008. The processing includes few jobs and sending e-mails after completion. I cann't do comparision here because before properties does not provide old values in the list item.Before you can deploy the event receiver you have to change the file to bind the Update Adding event receiver to all custom lists.Remember that if you want to develop event receivers for specific lists, you will have to work with content types.Together with Patrick we developed the alfa and beta versions of the Silverlight Blue Print for Share Point which contains several samples on how to integrate Silverlight with Share Point.
