Display all row from Databse into GridView using C# in ASP.Net

hi

I want bind gridview so I used belwo code:

  using (SqlConnection conn = General.GetConnection())
        {
            using (SqlCommand _cmd = General.GetCommand("ViewUserInfo", conn))
            {
                string ipAddress;
                ipAddress = Request.ServerVariables["HTTP_X_FORWARDED_FOR"];
                if (ipAddress == "" || ipAddress == null)
                    ipAddress = Request.ServerVariables["REMOTE_ADDR"];

                _cmd.Parameters.AddWithValue("@IPAddress", ipAddress);
                conn.Open();
                SqlDataReader _dr = _cmd.ExecuteReader();
                while (_dr.Read())
                {
                    LblMob.Text = _dr["Mobile"].ToString();
                
                    LblUsername.Text = _dr["Name"].ToString();
                    LblEmail.Text = _dr["Email"].ToString();
                    if (_dr["OrderType"].ToString() == "لینک دانلود")
                    {
                        if (_dr.HasRows)
                        {
                            GridView1.DataSource = _dr;
                            GridView1.DataBind();
                        }
                        createTemporaryLink();
                    }

                }
            }
        }

but it doesn't show data from first row of table...

AND SP:

ALTER procedure [dbo].[ViewUserInfo]
@IPAddress VARCHAR(50)
as 
begin

select *
from Temp_users
where IPAddress=@IPAddress
end

Best Regards
