Ajax back button problem

[binilprasad]

Hi friends
Am working on an ASP.NET project that uses ajax for filling the dropdown lists.Its a search page and user have to select some search criteria.Dropdowns are filled with data using ajax.After a search if user presses back button the dropdowns that are filled in client side is not maintaining the data.
How can i store the previous state to deal with the back button.?

Plz help.

The back button is completely controlled by the browser. It relies upon what the browser thinks is the correct cache for that page. I don't believe that there is a solution for this.

hi

Ya back button is browser's own thing.we cannot access that.I know that.
I found something in net.This article uses javascript to override the back button problem.I couldnt understand this fully but i am going through it.They are using IFrames for it.

There is also a javascript toolkit DOJO which is said to have solved back button problem.

Those who have problems with back button just go through it.

i thought the window's onload event is fired when you hit the "back" button. have you tried to run your "ajax" there? think it will work.

yes the onload event is fired.I need to call the binding functions again to show the previous data in dropdown.

But i stored all html containing the dropdowns in an hidden field and i am showing it again
