How to input data to DataGridview to MS Acess?

I am trying to create an Attendance Monitoring System, I wanna know how to input data from TextBox and dateTimePicker to DataGridView to Database and show the remaining data from database such as EmployeeID and EmployeeName. And also input the time and date. I am using MS Access and I already cready a database named Employee with EmployeeID as number, EmployeeName as text, InTime,OutTime and Date as Data/Time. Consult the file that I uploaded for more details, It's a windows form app.
