Ouch, 7 years ago I could barely make myself understood. I hope my English improved since then and I can better explain what I need <g>

What would be a record source for this grid? If I understand you correctly, I need to add new row, when a user hits enter, right? Would be tough to create this class.

As I wrote, I found, that I can't just use simple assign method, because a macro command gives me an error while execution.
