Carry Over Field Values

[tekyge]

Is there a way to carry over a field value from one page to the next with asp without using a form? Lets say i have a hidden field called ClientID and I want to carry over its value when I click a hyperlink going to the next page. Any one have a clue it would be grateful.

you can use a session variable...

session("myvar")=value

on the next page you can access session("myvar")

or put the value in the hyperlink using....

http://servername/mypage.asp?myvar=value

then on the next page you can retrieve using...

request.querystring("myvar")

I use the following code to hide query string values. Its a simple way of protecting your data that is passed onto another page. This keeps folks from modifing your query string to gather unathorized data from your db.

First I create a onClick event.

<script language="JavaScript">
function SetVar(strVar)
{
document.cookie = "Var" + "=" + strVar + ";";
}
</script>



Then I stuff the querystring with a value.

<A HREF="somepage.asp?ID=<%= rs("dbValue")%>" onClick="SetVar(<%=rs("dbValue")%>)">Click here</A>


The second page contains the following code.

intVar=Request.Cookies("var")
'now lets clear the contents of the cookie
Response.Cookies("var").expires= Date() - 5
'now lets redirect the user if an attempt to was made to modify query string
If intVar = "" Then
response.redirect("SecurityIssue.asp")
End If

I can't get it to work. I have a hidden field that carries an ID number and I want to carry the value oif this field over to the next page. I also want it to be in vb because some clients my not have java enabled and I would rather it be server side. Thanks guys.

My problem is Im not clear where "session("myvar")=value" goes on the page. I had it like this on the first page <%session("myvar")=value %> and like this on the next page <%= request.querystring("myvar") %> ?

 

[DotNetGnat]

if you have
session("myvar")=somevalue
then on the second page just access it using
session("myvar")

for testing...you can do a response.write on page 2...

response.write session("myvar")

Ok on first page I have:

<%session("ClientID")=value %>

Second Page:

<%= request.querystring("ClientID") %>

On first page all it shows is True

i am sorry to say but i would suggest you reading some basics at

http://www.w3schools.com

all the code i was providing so far is just a pseudo code...you need to replace with your own values and variables...

show us your complete code...

I did post the code, but I found another solution thanks.

Thanks dot For some reason the <%= session("ClientID") %> works now without anything on the first page it pulls the ID over to the hidden field like I wanted. What was confuseing me was it should work but was not responding. Thanks for your help

 

[tekyge]

Just so I don't confuse anyone the code is like Dot said:

Page one:
session("myvar")=blah

Page Two:
Calles session value from page one.
session("myvar")
