Hi :
I am new to implement design pattern in the application. I would like to implement design pattern to store / get history state of multiple controls in web application
what would be the best desing pattern to achieve this?
e.g would like to store history state of controls like Dropdown / textbox / Grid sorting / Grid Paging / Grid Filter etc.
when the browser back button hits , we also navigate through the history state and restore each and every controls according to its key / value pair .
I am thinking to use Observer pattern . but like to know more idea which is the best pattern that fits here.
