No the query string variables wont differ.
They will be same for each of the 5 URLs passed.
And, Session Variables will have to defined in Global.asax file. Is it?
Or my sender page?? And do i have to code it in Datagrid ItemCommad event?

I m trying using them...

You can code the session variables anywhere in the sending page. I would suggest the Page_Load event.

I have coded the following way in SENDER's Page_Load Event:
Dim compname as string
Dim countryname as string

Session(compname)=cmbcompany.SelectedValue
Session(countryname)=cmbcountry.SelectedValue

And retrieving it in RECEIVER's Page_Load Event the following way:

Dim comp, country as string
comp = Session(compname)
country = Session(countryname)

But here, am getting syntactical error that compname and countryname are not declared.
ie m not able to access the session variables in receiver's page...

Can u tell me whats d prb...
