            da.SelectCommand = new SqlCommand("select * from guestinfo");
            return "done";

        public void add()
            guests gus = new guests();

            string ConString = @"Data Source=USER-PC\SQLEXPRESS;Initial Catalog=htm;Integrated Security=True";

            guests gst = new guests();
            gst.Guest_id = Convert.ToInt32(guest_id.Text.ToString());
            gst.First_name = first_name.Text.ToString();
            gst.Last_name = last_name.Text.ToString();

Do you see any paramters in your stored procedure? No you do not. Then why are you providing them in lines 87-93?

then what i write in code...can u plzz tell me?

yeah i correct it but when i again debug then there is error in line number 69.....??

You didn't add a connection to the SqlDataAdapter. Change line 68 to

da.SelectCommand = new SqlCommand("select * from guestinfo", con);

but when i click add and view button then any inforamtion not show and add in gridview

and in sql database which i add a entry in guesttable this entry not view in gridview when i click vew button????

can u tell me plz

In line 70, right after you fill the dataset, you clear it, so there is nothing in it.

so what i wirte????

plzz anyone tell me???? =(

simple, now comment line 70.

yes i commented but not add info

your method named displaydata() returns a string and you are binding a string to the datasource of a grid, which can never happen.
change your return type from string to datatable or dataset and then bind the result to the gridview. it will work.
i suppose there is a problem with the basics.
