Hi Martin,

Thank you for the listed details.

I have tested the behavior and indeed a row is added and afterward, an exception is thrown. We need to handle this scenario at the beginning of the Add() method and throw an exception that the null parameter can't be added as a row. I will approve the feedback item. As soon as our team starts working on the item to provide a fix, we will update the status so that you can be notified. 

I have updated your Telerik Points for bringing this to our attention.
