Kindly change your code in the following format.
string conn = "Data Source=SACHIN;Initial Catalog=sample;Integrated Security=SSPI;User ID=";
SqlConnection sqlcon = new SqlConnection(conn);
sqlcon.Open();
SqlCommand comm = new SqlCommand("Insert into table1 (User_Name,User_Password) values (@username,@password)", sqlcon);
comm.Parameters.AddWithValue("@username", TextBox1.Text.ToString());
comm.Parameters.AddWithValue("@password", TextBox2.Text.ToString());
comm.ExecuteNonQuery();
