Why does my program not work on the second page of its movement function and does not give an error?

Question

I need two pages in my program, one for entering and other one for record information and save in the database, both of which I have prepared at designer, but on the second page, the movement function does not work due to the borderless window and the page is fixed, please help me Thank you
