Answer 1

Try with such a loop

 string str = "";
            for (int i = 0; i <= 29; i++)
            {
                if (CheckBoxList1.Items[i].Selected)
                {
                    string b = CheckBoxList1.Items[i].Value;
                    str += b + " , ";
                }

            }

than make an insert statement and you are putting all the checkbox values into a column. than just call select statement call the column

You are doing a very bad thing storing lists of values in a single MSSQL column. I know it may be convenient now, but it is always eventually bad news. Why not store booked seats in their own table, one seat per row? When you store a list of values in a column, you restrict access to the information stored in that column to only the code that can split the list. It isn't available to database queries or to other code as a list, merely as a string. You will end up replicating the code to split this string to other places that need the list data.
