Hi
I have developed a web page with some controls. I put all of them in
session variables. I passed this values in the page. When an user
enter some data in form fields and click the buttton , these values
are displaying in next page.after displaying in next page, when click
back button to see my entered values for change , no values are in the
form fields. the fields are empty .I tried with enable view state=true
in controls and at the top of the page.but it doesn't work.
any one help would be appriciated.
Here is the code in two pages.
