It will be helpful to see it of course, If you don't mind. I also don't have much time to play around with it, thats why I posted here because I'm in a hurry.
I did some research and thought about using GroupBy but was not sure whether it will change the order of items after grouping. Also I have a lot more other properties and I don't want to use Select after grouping them. Can you show me how you did it :?
