            da = new SqlCommand("INSERT INTO tblBooks VALUES(@Book_ID, @Title, @ISBN_No, @Author, @Publisher, @Date_Published, @Available, @Price)", cs);
            da.Parameters.Add("@Book_ID", SqlDbType.Int).Value = textBox1.Text;
            da.Parameters.Add("@Title", SqlDbType.VarChar).Value = textBox2.Text;
            da.Parameters.Add("@ISBN_No", SqlDbType.NChar).Value = textBox3.Text;
            da.Parameters.Add("@Author", SqlDbType.VarChar).Value = textBox4.Text;
            da.Parameters.Add("@Publisher", SqlDbType.VarChar).Value = textBox5.Text;
            da.Parameters.Add("@Date_Published", SqlDbType.DateTime).Value = DateTime.Parse(textBox6.Text);
            da.Parameters.Add("@Available", SqlDbType.Bit).Value = textBox7.Text;
            da.Parameters.Add("@Price", SqlDbType.Money).Value = textBox8.Text;

            cs.Open();
            da.ExecuteNonQuery();

This is the parameter you have issues, right?:

da.Parameters.Add("@Available", SqlDbType.Bit).Value = textBox7.Text;

Bit can only have "true" or "false" values in th database.
What is your value in textBox7?

Its you have 1 or 0 do a conversation to true or false.

EDIT:
and instead of textBox6, in which you have date, you better use dateTimePicker ot monthCalendar. In this case there will never come to any inconveniances in capturing the right date value.

This error might occur becuase you attempted to insert a row containing a specific identity value into a table that contains an identity column.

Now, you must specify the column list of the Product column when u use the IDENTITY_INSERT ON.

Check for the colution here:http://www.sql-server-helper.com/error-messages/msg-8101.aspx
