Button Clicked and Post button clicked

What is the difference between Button clicked and POst button clicked controls in form design.

Also can anybody provide with a documentation on Controls and Event rules in Form design.

Thanks in Advance

Hi,
As a general rule there is only difference in case of buttons that have some automatic functionality (e.g. OK, Find). Button Clicked is before this automation runs and Post Button Clicked is after.
In the rest of the cases these are just two events after each other.
