Solution 1

You can store the selected value of droplanguage in a session variable on SelectedIndexChanged event like this:

Session["DropLang_Value"] = droplanguage.SelectedValue;

You can then access and fetch value of this session variable on Order.aspx like this:

string dropLangVal = Session["DropLang_Value"].ToString();

Hope this will help you. :)

Ok, so you can give an initial value as "English" to that session variable and change it if user selects some other value from droplanguage, so that its value won't be null at any time.

Why r u setting initial value to drop down list???
Set initial value to Session variable as Session["DropLang_Value"] = "English".
Then, on SelectedIndexChanged event of droplanguage, set the value of that session variable.
