in first page use like this.

page1.aspx:
--------------
string usr = "user";
int i = 15;
Response.Redirect("Default.aspx?name="+usr+"&value="+i.ToString());

Explain:
here i passed two values one string that is user, and second one integer is just 15;

you can access this value in second page like below code..

Default.aspx:
----------------
int i;
string user;
protected void Page_Load(object sender, EventArgs e)
{
user = Request.Params["name"];
i = Convert.ToInt32(Request.QueryString["value"]);
}
button click time access get your value in label.
protected void btnSubmit_Click(object sender, EventArgs e)
{
lable1.Text=user.Tostring();
lable2.Text=i.Tostring();
}

i hope this is useful to you...
take care bye....
