jQuery Grid Plugin - jqGrid

Hi. I want to create an attendance sheet.

In it, It will display the first name and the last name from a database (MemberInfo), and then will give me some empty fields for the days of the week, where i would write 1 if the person was on time, and 2 if the person was late. 

The data would have to be saved in a database table (Attendance) if the field was filled up and when I pull up the attendance sheet again, the fields that were filled up before should be filled.

So far I have been able to add the columns for the days of the week and to save the data with cellEdit, the only think that I'm having problem is how to load the data in the first place.

I've been trying to get this done but have no idea how to. Any ideas? Thanks!
