Thank you. I'm glad I could point you in the right direction.
Additionally, and perhaps related, I get some weird behavior when I have a locked cell with a dropdown editor. I don't have a need to have a dropdown editor in a locked column, so its not a concern for me. However, while experimenting, I noticed that the k-grid-edit-row class won't disappear from the non-locked columns.
Let me know if you would like more info.
