Is there any oprtion to write code foe adding new row to Repeating table?  I dont want to use the default "insert item menu" of the Repeating table. I want to add to the form my own button and to write code on it's OnClick event.

Yes this is possible. Just search the forum, I know that this has been discussed already a several times. I also already posted some threads about it. Just do a little research and you will find what you need.
