Again guys this is also about web pages, do you ever wanted to pass a value from a page to another , this is the most fundamental way of doing it .So lets say you have a textBox accepting name of the user , and you want to set that value to a label in next page .
this is the simple way....
// hfCode is a hiddenField and txtLogin is my textbox, and Login ,code are my parameters.
Response.Redirect("URladdress.aspx?Login=" + txtLogin.Text + "&Code=" + hfCode.Value);
So in the receiving end or the page all you have to do is ,
if (Request.QueryString["Login"] != null && Request.QueryString["Code"])
lblWelcome.Text = "Welcome "+ Request.QueryString["Login"]
}+" "+ Request.QueryString["Code"];
P.S. make sure to check that parameters are not null before accessing
