    Hello,

     According to your code you've not specified SourceField for the SumFunction.

    I have tested that, even after specifying SourceField same exception occurs.

    Demostration? It's a production code which I can not share (not even snaps). Collection binded to Grid has 6 rows and none of the value is null.
    Still when for Collection Property PropertyChanged event raised, Exception listed with StackTrace mentioned above occurs. Version I mentioned in initial post.

    Hello Vikas,

    We are not aware of such issue and we cannot provide you with any further assistance without reproducing the problem on our side. I understand your position that your project may have some sensitive data. You can follow the steps described in this blog post on how to prepare a dummy project which demonstrates the problem without any sensitive data in it.

    All the best,
