Nadya,
Cetin answered your other questions, but I have some comments on your object references.

Often you'll have form methods that will refer to data on more than one container. In this case, pass the container as an object to the form method. For example if you wanted to run the same calculation when data is updated in Page1.container1 and Page2.container1 you'd call it from a textbox Valid() with Thisform.MyNextCalc(this.parent) Note that here "this.parent" refers to the container. If you have containers INSIDE containers you might have to adjust that.
