Hi All,

I have developed a web application and the when user goes back all the entries are expired. I want that when user goes back, all the entries they entered on the last page are viewable.

For example if a user entered like :

first page : User Name,User_ID<br />
Second Page : Q1<br />
Third Page : Q2<br />
Fourth Page : Q3<br />
Fifth Page : Q4<br />
Sixth Page : Complete

In database answer will save according to User ID. Query is like :

Update Q1= "value" where User_ID = @User_ID
Update Q2= "value" where User_ID = @User_ID
Update Q3= "value" where User_ID = @User_ID

So if user want to edit Q2 again then he can go back and edit the last answer but in my case when user go back then his last answer will save in database but not on the page. So i want whenever he want to review or edit the previous answers before complete he can go and edit it.

Any help is appreciated.

Thanks.

To restore those values when revisiting a page, you need to load them from the database and populate the fields in the output with the values you retrieved.

If user hits back button of browser, then he can see the values, but I think that you may have one back button in all pages which redirects it to the previous page.

As a button is clicked, always a post back happens; so the page again reloads with no values.

For your problem, you can store all the values in session variables when you move to next page.
And when back button is pressed(i.e. the previous page loads), you have to check for the existence of the session values in previous page and if they exist, then give their values to appropriate controls in your pages.

It's actually browser dependent whether it will reload values into a page you go 'back' to. I think Chrome and Firefox will only re-fill the form if it retrieves the page from cache, so if it's marked as non-cachable by the server then it will reload it and not re-fill. The questioner may have to update his template or ASP config to make these pages cachable (i.e. don't send the Pragma: no-cache and set the cache expiry to at least a few minutes in the future).

Ok I will do. But do you need it urgently????

If you can send me your codes, then I can do it fast. Otherwise it will take some time....

ok here I can tell you how to do it.
I think you must have written - Response.Redirect("Next_Page.aspx"); somewhere after getting the values of the controls.

Just before this line add the codes for the conrol values u want to store like below -

Session["UserName"] = txtUserName.Text;
Session["UserID"] = UserID;
and so on.....

And then in previous page load check whether these value are in session or not, then fill values to appropriate controls as below...

Inside Page_Load() ----
if(Session["UserName"] != NULL)
{
txtUserName.Text = Session["UserName"].ToString();
}
if(Session["UserID"] != NULL)
{
txtUserID.Text = Session["UserID"].ToString();
}
and so on.....
