Hello All,

I have a form where i have a dynamic dropdowm box.

On selection of Ist box values the second combobox gets populated.

Everything is fine here. On submit of this page, the form moves to another where the user previews his details.

The problem here is once the user say back/previous, the user moves to the form
where all the fields are populated as the user selected previously but the dynamic box remains blank till the user selects some other values and then the values he requires.

I know on clicking back the form uses history(-1) function, where it is not possible to retrieve the dynamic values.

Could sessions be used here, if yes/or no please help me?


Thank you!!

Hello All,

any help or suggestions?

One way could be to pass the values back to the original page using query strings.

It is a tad draconian but would work.

Cheers

The only way Aspless's solution would work (that I can see) is if the user were to use some sort of on page navigation (a button or link) that would link back to the first form. If the user hits the 'Back' button in the browser there is no way for you to control what is passed in the query string. Furthermore, hitting the back button in your browser pulls the pages from the browser cache thus the page isn't actually reloaded.

What might resolve your problem is to set some sort of Session variable with the value you are interested in and set the first form page to not cache; this would mean every time someone goes to that page it would have to be served up from the Web Server and not pulled from the browser cache. You would merely need to check for the existence of this session value and, if it is present, populate the box otherwise leave it alone.

hth.
