Solution 1

YOU can navigate by button click to any direction like prev and nest like this for previous

HTML

<input action="action" type="button" value="Back"  önclick="history.go(-1);" />

ASP.NET

<head  runat="server">
    <title></title>
    <script type="text/javascript">
        function Navigate() {
            alert('hi');
            history.go(-1);
        }
    </script>
</head>
<body>
    <form id="form1"  runat="server">
    
    <input action="action" type="button" value="Back"   önclick="Navigate();" />
    
    </form>
</body>
</html>

Try this:

In page load:

what is the previousPage here ?is a string variable ?

Tom Marvolo Riddle 2-Apr-14 7:12am

Yes.Name it as Static String

Member 10273293 2-Apr-14 7:23am

this is also not working

Tom Marvolo Riddle 2-Apr-14 7:30am

Not Working------Not at all informative.Please don't just say not working.This is the working code i had used in many projects

Do one thing for me
In page 1: -------Redirect to page 2//Response.Redirect("page2.aspx");
In page 2:
1.In page load:
previousPage = Request.UrlReferrer.ToString();

Place a button in page2
in button click event post this:
Response.Redirect(previousPage);

Try it

I get confused with this:

if user select a radio button and go to the next page but suddenly click the previous page all the checked show as it is as he/she has done . what does it mean?

will you explain?

Member 10273293 2-Apr-14 8:19am

if user choose the second radiobutton on default2.aspx page and than go to the next page default3.aspx but if he she press previous button on default3.aspx page so again redirect to default2.aspx page but now on default2.aspx page all readiobutton are unchecked i just wanted that all previous page maintain their value as user choosed

Tom Marvolo Riddle 2-Apr-14 8:26am

Then this i wanted to code previous button coding as like chrome browser back button part has no connection with next part.Make the question clear as much as possible.

Both 1,2 solutions are totally irrelevant to your explained part.we gave solution to this i wanted to code previous button coding as like chrome browser back button

let come to the current issue
