I have an issue, with this event. What my purpose is: i want to update one of the properties based on few criterias, so i want do fill a field A if field A is empty and the field B is not empty and field C is also not empty.
How to do it properly because with on ItemUpdating some afterproperties are sometimes null or they dont exist at all etc etc ..
Any good advice?
Just to let you know it is about SharePoint 2007
Update: the problem is that i need to compare if the previous value and the new value: so if someone updates an item.
EX: current Item : title=value1; title2= value1
someone updates accordingly: title=newValue
updated item should have following value: title=newValue; title2 = newValue
next time following update: title2=againANewValue;
updated item should be as follwoing: title=againANewValue; title2=againANewValue;
So basically both of the fields should stay synchronised nno matter which one is updated, so I can't know which one of the fields was updated and then which one i should update ..
